Hair & Nails

Hair loss is an exceedingly common chief concern in outpatient dermatology clinics. An estimated 50% of males and females will experience androgenetic alopecia.¹ Approximately 2% of new dermatology outpatient visits in the United States and the United Kingdom are for alopecia areata, the second most common type of hair loss.² As access to dermatology appointments remains an issue with some studies citing wait times ranging from 2 to 25 days for a dermatologic consultation, the ease of accessibility of medical information on social media continues to grow,³ which leaves many of our patients turning to social media as a first-line source of information. As dermatology resident physicians, it is essential to be aware of popular dermatologic therapies on social media so that we may provide evidence-based opinions to our patients.

Remedies for Hair Loss on Social Media

Many trends on hair loss therapies found on TikTok focus on natural remedies that are produced by ingredients accessible to patients at home and over the counter, which may increase the appeal due to ease of treatment.

Rosemary Oil—The top trends in hair loss remedies I have come across are rosemary oil and rosemary water. Rosemary (Rosmarinus officinalis) has been known to possess antimicrobial and antioxidant properties but also has shown enhancement of microcapillary perfusion, which could explain its role in the prevention of hair loss and aiding hair growth in a similar mechanism to minoxidil.^4,5 Unlike many other natural hair loss remedies, there are randomized controlled trials that assess the efficacy of rosemary oil for the treatment of hair loss. In a 2015 study of 100 patients with androgenetic alopecia,there was no statistically significant difference in mean hair count measured by microphotographic assessment after 6 months of treatment in 2 groups treated with either minoxidil solution 2% or rosemary oil, and both groups experienced a significant increase in hair count at 6 months (P<.05) compared with baseline and 3 months.⁶ Additionally, essential oils, including a mixture of thyme, rosemary, lavender, and cedarwood oils for alopecia were superior to placebo carrier oils in a posttreatment photographic assessment of their efficacy.⁷

Rice Water—The use of rice water and rice bran extract is a common hair care practice in Asia. Rice bran extract preparations have been shown in vivo to increase the number of anagen hair follicles as well as the number of anagen-related molecules in the dermal papillae.^8,9 However, there are limited clinical data to support the use of rice water for hair growth.¹⁰

Onion Juice—Sharquie and Al-Obaidi¹¹ conducted a study comparing crude onion juice to tap water in 38 patients with alopecia areata. They found that onion juice produced hair regrowth in significantly more patients than tap water (P<.0001).¹¹ The mechanism of crude onion juice in hair growth is unknown; however, the induction of irritant or allergic contact dermatitis to components in crude onion juice may stimulate antigenic competition.¹²

Garlic Gel—Garlic gel, which is in the genus Allium, produces organosulfur compounds that provide antimicrobial and anti-inflammatory benefits.¹² Additionally, in a double-blind randomized controlled trial, garlic powder was shown to increase cutaneous capillary perfusion.⁵ One study in 40 patients with alopecia areata demonstrated garlic gel 5% added to betamethasone valerate cream 0.1% was statistically superior to betamethasone alone in stimulating terminal hair growth (P=.001).¹³

Limitations and Downsides to Hair Loss Remedies on Social Media

Social media continues to be a prominent source of medical information for our patients, but most sources of hair content on social media are not board-certified dermatologists. A recent review of alopecia-related content found only 4% and 10% of posts were created by medical professionals on Instagram and TikTok, respectively, making misinformation extremely likely.¹⁴ Natural hair loss remedies contrived by TikTok have little clinical evidence to support their claims. Few data are available that compare these treatments to gold-standard hair loss therapies. Additionally, while some of these agents may be beneficial, the lack of standardized dosing may counteract these benefits. For example, videos on rosemary water advise the viewer to boil fresh rosemary sprigs in water and apply the solution to the hair daily with a spray bottle or apply cloves of garlic directly to the scalp, as opposed to a measured and standardized percentage. Some preparations may even induce harm to patients. Over-the-counter oils with added fragrances and natural compounds in onion and garlic may cause contact dermatitis. Finally, by using these products, patients may delay consultation with a board-certified dermatologist, leading to delays in applying evidence-based therapies targeted to specific hair loss subtypes while also incurring unnecessary expenses for these preparations.

Final Thoughts

Hair loss affects a notable portion of the population and is a common chief concern in dermatology clinics. Misinformation on social media continues to grow in prevalence. It is important to be aware of the hair loss remedies that are commonly touted to patients online and the evidence behind them.

HONOLULU – Nearly every day, Candrice R. Heath, MD, spends time during office visits dispelling myths about hair care practices in patients with skin of color. One myth is the idea that not washing hair helps it to grow.

“This is false,” Dr. Heath, director of pediatric dermatology at Temple University, Philadelphia, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! With little manipulation, length may be retained, since tightly coiled hair has a higher likelihood of breakage, she said. “But washing the scalp and hair is recommended for tightly coiled hair weekly or every other week. Exclusively co-washing – a technique where hair conditioner is used instead of shampooing – is also not advised due to scalp build-up.”

Other myths she addressed include the following:

“I have a weak spot (or stress spot) on the top of my scalp.” These terms may be used to describe hair on a spot that goes through cycles of breaking off and re-growing. This is false. “If someone were to say that, and we see short hairs on the top of a patient’s scalp, with or without tenderness, pruritus, or pain, we want to recognize that as possibly an early sign of central centrifugal cicatricial alopecia [CCCA],” she said. “We want to pick up cases of CCCA forme fruste [central hair breakage] early.”

Medicated shampoos are helpful for all patients with seborrheic dermatitis. This notion is more complicated. “In theory, medicated shampoos like ketoconazole should be helpful, but if the shampoos are too drying for the hair and they cause further hair breakage, that’s going to be a problem as well,” explained Dr. Heath, who was the senior author of an article on how to address common conditions affecting pediatric and adolescent patients with skin of color. For patients with tightly coiled hair, she recommends applying antifungal shampoos to the scalp only, waiting 5-10 minutes, rinsing, and shampooing the scalp and hair with a moisturizing shampoo and rinsing. They can then condition with a moisturizing conditioner and style their hair as desired.

The often-delayed diagnosis of isolated nail psoriasis (NP), along with the possibility of a “reciprocal relationship” with psoriatic arthritis, “should serve as an impetus for dermatologists to improve their diagnostic accuracy,” investigators said in a research letter.

Diagnosis of isolated NP was delayed by almost 3 years among the 87 cases recorded and “arthritis was most often diagnosed concurrently with NP,” at a major nail referral center between Jan. 1, 2001, and Dec. 21, 2022, Michelle J. Chang of Drexel University, Philadelphia, and associates reported.

In what the authors say is, “the largest study documenting clinical and histologic features in patients with isolated NP,” the two most common clinical features were onycholysis and nail plate pitting, seen in 79% and 70% of cases, respectively. No other single feature had a prevalence higher than 28%.

The most frequent clinical dyad was onycholysis and pitting in 66% of patients, followed by onycholysis/nail thickening in 33% and onycholysis/splinter hemorrhage in 32%. The most common histologic features were parakeratosis in 79% and neutrophil infiltration in 48%, the investigators said.

Psoriatic arthritis (PsA), a focus of the study, occurred in 10 (11%) of the 87 individuals with isolated NP. Considering this finding, and “the close proximity between the nail apparatus and joint, we hypothesize a reciprocal relationship, with nail unit inflammation precipitating PsA,” Ms. Chang and associates wrote.

Senior author, Shari Lipner, MD, PhD, of the department of dermatology, Weill Cornell Medicine, New York, is a consultant for Ortho-Dermatologics, Hoth Therapeutics, and BelleTorus. Ms. Chang and the two other investigators had no conflicts of interest to declare.

HONOLULU – Combining cryotherapy, salicylic acid, and fluorouracil (5-FU) can improve the efficacy of treating common warts, but topical or intralesional cidofovir may be required for recalcitrant lesions or those located in areas that are challenging to treat, according to John S. Barbieri, MD, MBA.

“There are 5 million office visits per year in the United States for warts and molluscum, and they’re most common in pediatrics,” Dr. Barbieri, of the department of dermatology at Brigham and Women’s Hospital, Boston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “In fact, some studies have suggested that one in three children in primary school suffers from warts.”

Doug Brunk/MDedge News

According to a 2012 Cochrane review of topical therapies for warts, first-line treatments such as salicylic acid, cryotherapy, 5-FU, or Candida antigen injection often have modest efficacy when used alone. For example, the authors found that salicylic acid and cryotherapy cleared warts in about 60%-70% of cases, respectively, but clearance rates were improved by combining the two therapies.

In an earlier literature review and meta-analysis, investigators evaluated the effect of 5-FU plus salicylic acid or salicylic acid alone. The therapeutic effect for common warts across all studies was a 63.4% response rate (complete healing) for 5-FU/SA vversus 23.1% for the 5-FU–free controls, respectively. For plantar warts, the response rate was 63% versus 11%, respectively.

“But what about the person with multiple warts or those in challenging locations where you might worry about destructive treatments hurting the nail fold or causing nail dystrophy?” Dr. Barbieri asked. “Maybe they’ve used salicylic acid or intralesional Candida and they’re still not getting better. What can we do for these patients?”

Emerging research suggests that topical cidofovir can be a valuable option for recalcitrant warts or those in sensitive locations. In a case report of a 10-year-old boy with more than 50 severe verrucous papules on his hands and face that were recalcitrant to multiple conventional therapies, topical 1% cidofovir applied daily for 8 weeks was effective, with no adverse side effects. A young female patient who presented to Dr. Barbieri with multiple warts around the nail matrix of several fingers experienced complete clearance after treatment with topical cidofovir, he said. Other researchers found this approach to be effective for plantar warts as well, in a report of two brothers with severe combined immunodeficiency after hematopoietic stem cell transplantation with persistent warts that did not respond to traditional topical treatments.

“Topical cidofovir is typically a painless treatment, which is nice, especially for our pediatric patients who might be afraid of other therapies like or cryotherapy or intralesional injections,” One limitation is that it is “a bit expensive,” Dr. Barbieri said. “To have topical cidofovir compounded is typically $100-$300, depending on the quantity and strength that you ask for.”

Intralesional cidofovir is another treatment option. In a retrospective study of 58 patients, Dr. Barbieri and colleagues evaluated the outcome of intralesional cidofovir treatment of warts in immunocompromised and nonimmunocompromised patients. Rates of improvement ranged from 98.3% to 100%, while resolution rates ranged from 75.9% to 97.6%.

“Most of the patients had warts for more than 5 years and almost half of them had recalcitrant warts,” Dr. Barbieri said. “These were mostly adult patients, but I think this is a treatment that can work in younger populations as well. About 10%-15% had HIV or cancer or diabetes or were transplant recipients, but despite these challenges and despite these recalcitrant warts, about 100% had improvement.”

He pointed out that cidofovir is available as a 75 mg/mL vial that comes with a 5 mL single-use vial. He dilutes this with normal saline to create a 15 mg/mL solution.

“If you want to be efficient you can try to schedule multiple patients together on the same day as a single vial is sufficient to treat about 25 patients,” assuming about 1 mL is injected per patient, he said. “The challenge with intralesional cidofovir is that it’s painful beyond just the needle part of the injection. Sometimes a nerve block can be helpful. But this can be an effective treatment for patients with recalcitrant warts or those with comorbidities.”

Other intralesional therapies to try for recalcitrant warts, he said, include bleomycin (1 U/mL solution, 1-2 mL per treatment, spaced every 2-4 weeks), and 5-FU (a 4:1 mixture of 5-FU [50 mg/mL] and 2% lidocaine).

Dr. Barbieri disclosed that he receives consulting fees from Dexcel for work unrelated to his presentation. Medscape and this news organization are owned by the same parent company.

Other intralesional therapies to try for recalcitrant warts, he said, include bleomycin (1 U/mL solution, 1-2 mL per treatment, spaced every 2-4 weeks), and 5-FU (a 4:1 mixture of 5-FU [50 mg/mL] and 2% lidocaine).

HONOLULU – Combining cryotherapy, salicylic acid, and fluorouracil (5-FU) can improve the efficacy of treating common warts, but topical or intralesional cidofovir may be required for recalcitrant lesions or those located in areas that are challenging to treat, according to John S. Barbieri, MD, MBA.

“There are 5 million office visits per year in the United States for warts and molluscum, and they’re most common in pediatrics,” Dr. Barbieri, of the department of dermatology at Brigham and Women’s Hospital, Boston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “In fact, some studies have suggested that one in three children in primary school suffers from warts.”

According to a 2012 Cochrane review of topical therapies for warts, first-line treatments such as salicylic acid, cryotherapy, 5-FU, or Candida antigen injection often have modest efficacy when used alone. For example, the authors found that salicylic acid and cryotherapy cleared warts in about 60%-70% of cases, respectively, but clearance rates were improved by combining the two therapies.

In an earlier literature review and meta-analysis, investigators evaluated the effect of 5-FU plus salicylic acid or salicylic acid alone. The therapeutic effect for common warts across all studies was a 63.4% response rate (complete healing) for 5-FU/SA vversus 23.1% for the 5-FU–free controls, respectively. For plantar warts, the response rate was 63% versus 11%, respectively.

“But what about the person with multiple warts or those in challenging locations where you might worry about destructive treatments hurting the nail fold or causing nail dystrophy?” Dr. Barbieri asked. “Maybe they’ve used salicylic acid or intralesional Candida and they’re still not getting better. What can we do for these patients?”

Emerging research suggests that topical cidofovir can be a valuable option for recalcitrant warts or those in sensitive locations. In a case report of a 10-year-old boy with more than 50 severe verrucous papules on his hands and face that were recalcitrant to multiple conventional therapies, topical 1% cidofovir applied daily for 8 weeks was effective, with no adverse side effects. A young female patient who presented to Dr. Barbieri with multiple warts around the nail matrix of several fingers experienced complete clearance after treatment with topical cidofovir, he said. Other researchers found this approach to be effective for plantar warts as well, in a report of two brothers with severe combined immunodeficiency after hematopoietic stem cell transplantation with persistent warts that did not respond to traditional topical treatments.

“Topical cidofovir is typically a painless treatment, which is nice, especially for our pediatric patients who might be afraid of other therapies like or cryotherapy or intralesional injections,” One limitation is that it is “a bit expensive,” Dr. Barbieri said. “To have topical cidofovir compounded is typically $100-$300, depending on the quantity and strength that you ask for.”

Intralesional cidofovir is another treatment option. In a retrospective study of 58 patients, Dr. Barbieri and colleagues evaluated the outcome of intralesional cidofovir treatment of warts in immunocompromised and nonimmunocompromised patients. Rates of improvement ranged from 98.3% to 100%, while resolution rates ranged from 75.9% to 97.6%.

“Most of the patients had warts for more than 5 years and almost half of them had recalcitrant warts,” Dr. Barbieri said. “These were mostly adult patients, but I think this is a treatment that can work in younger populations as well. About 10%-15% had HIV or cancer or diabetes or were transplant recipients, but despite these challenges and despite these recalcitrant warts, about 100% had improvement.”

He pointed out that cidofovir is available as a 75 mg/mL vial that comes with a 5 mL single-use vial. He dilutes this with normal saline to create a 15 mg/mL solution.

“If you want to be efficient you can try to schedule multiple patients together on the same day as a single vial is sufficient to treat about 25 patients,” assuming about 1 mL is injected per patient, he said. “The challenge with intralesional cidofovir is that it’s painful beyond just the needle part of the injection.

HONOLULU – In the clinical experience of April W. Armstrong, MD, MPH, topical therapies typically don’t work well for nail psoriasis, so she sometimes resorts to intralesional injections combined with systemic therapy.

One might think of intralesional injections “as a torture method from the medieval days,” she said at the Hawaii Dermatology Seminar provided by MedscapeLIVE!, but intramatricial corticosteroid injections have been performed for many years as a treatment for nail psoriasis, typically with triamcinolone acetonide.

According to Dr. Armstrong, professor of dermatology and associate dean of clinical research at the University of Southern California, Los Angeles, nail matrix psoriasis can present as pitting, leukonychia, red macules in the lunula, crumbling, or trachyonychia. Nail bed psoriasis can present as splinter hemorrhages and onycholysis, hyperkeratosis and splinter hemorrhages, salmon patch or oil spot dyschromia, or onycholysis and salmon patch dyschromia.

In a German cross-sectional study of patients with psoriasis, nails were one of the body sites that have the greatest impact on quality of life – especially those in younger age groups.

While topical treatments are generally considered first for limited disease involving special areas such as the nails, systemic therapy is warranted in patients with moderate-to-severe involvement of specific sites or in those refractory to topical therapy, Dr. Armstrong said.

In 2018, Indian researchers published results from an open-label study of 17 patients, with nail psoriasis, comparing three treatments . Patients were assigned to three groups of 30 nails each and treated with intramatricial injections of triamcinolone acetonide (10 mg/mL), methotrexate (25 mg/mL), and cyclosporine (50 mg/mL), respectively. Each nail was treated with two injections at 6-week intervals and graded at 24 weeks using the Nail Psoriasis Severity Index (NAPSI). In the triamcinolone acetonide and methotrexate groups, 50% of treated nails showed a greater than 75% improvement at 24 weeks, compared with 33% of those in the cyclosporine group. The most side effects occurred in the nails treated with cyclosporine.

When Dr. Armstrong performs intramatricial injections, she uses triamcinolone acetonide at 10 mg/mL. However, she said, “my favorite way of treating severe nail psoriasis is with biologics.”

In an early study of patients with moderate to severe psoriasis treated with the tumor necrosis factor blocker adalimumab 80 mg subcutaneously at week 0, followed by 40 mg subcutaneously every other week from weeks 1 to 15, a post hoc analysis on the effects on nail psoriasis showed a 10-point decrease in the median NAPSI score through week 16 – from 21 to 11 .

In VOYAGE 2, which compared the interleukin-23 blocker guselkumab and adalimumab in patients with moderate to severe psoriasis, the mean percent improvement from baseline in the NAPSI score was similar in patients treated with adalimumab or guselkumab at week 16 (39.6% vs. 46.9%, respectively) and at week 24 (55% vs. 53.7%).

In another study of patients with nail psoriasis, researchers evaluated the efficacy of the IL-17A antagonist secukinumab 150 mg, 300 mg, or placebo at weeks 0, 1, 2, 3, and 4, and every 4 weeks thereafter for 2.5 years. At 2.5 years, the mean reduction in NAPSI score was 63.6% in the secukinumab 150 mg group and 73.3% in the secukinumab 300 mg group.

“I do have to tell my patients what to expect, because the nails grow out slowly, but over time we do see this increase in efficacy,” Dr. Armstrong said.

Studies of another IL-17A antagonist, ixekizumab, have yielded positive results as well, she noted. In 2021, Taiwanese researchers published a systematic review and network meta-analysis to evaluate the efficacy of small molecule inhibitors and biologics in treating nail psoriasis. They drew from 39 studies involving 15,673 patients with nail psoriasis and found that the oral Janus kinase inhibitor tofacitinib and ixekizumab had the best efficacy for treating nail psoriasis in 10-16 weeks and 24-26 weeks, respectively.

“They found that overall, the biologics have a good effect on nail psoriasis and that the treatment effects are overall quite similar,” Dr. Armstrong said.

Dr. Armstrong disclosed that she is a consultant or adviser for numerous pharmaceutical companies. She has also received research funding from Bristol-Myers Squibb, Dermavant, Dermira, Leo, Lilly, Pfizer, and UCB Pharma.

ORLANDO – From differentiating them from mimics to choosing the best treatment course, Molly Hinshaw, MD, reviewed some of the ins and outs of managing nail disorders at the ODAC Dermatology, Aesthetic, & Surgical Conference.

Dr. Hinshaw, professor of dermatology at the University of Wisconsin, Madison, reviewed several disorders and provided guidance on diagnosis, and achieving the best outcomes for patients.

Pyogenic granuloma (PG) in the nail: These are benign vascular tumors that can mimic more serious conditions, Dr. Hinshaw said. In adults, PG requires a histologic diagnosis, she said.

“So these all really should have a biopsy,” because of potential confusion with amelanotic melanoma or squamous cell carcinoma, she said, although in children, a biopsy is likely not necessary.

Treatment with topical beta-blockers can be effective for PG, she said, and avoids the scarring seen with surgical removal. “These are benign conditions – we want them to go away, but we want these patients to have a functional nail thereafter.”

Periungual or subungual warts: For these warts, which are alongside or under the nail, destructive approaches can cause scarring of the nail bed and are far from optimal, she said.

“We’d like to avoid that, of course.” Therefore, treatments such as lasers and liquid nitrogen “would be much further down, if at all, on my list,” she said.

Injections of the antiviral cidofovir, into the dermis right under the wart, can be highly effective, and one or two treatments is often enough, Dr. Hinshaw said. Sometimes, local anesthesia isn’t even needed for the injection, she said. “This is a wonderful option,” she added.

Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.

Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.^1,2

This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.³ In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.⁴ Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.¹

What’s the differential diagnosis?

The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.

Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.

A California woman developed skin cancer after getting a cut during a manicure. Now, she and her doctor are spreading the word about her ordeal as a lesson that speed and persistence in seeking treatment are the keys that make her type of cancer – squamous cell carcinoma – completely curable.

“She cut me, and the cut wasn’t just a regular cuticle cut. She cut me deep, and that was one of the first times that happened to me,” Grace Garcia, 50, told TODAY.com, recalling the November 2021 incident.

Ms. Garcia had been getting her nails done regularly for 20 years, she said, but happened to go to a different salon than her usual spot because she couldn’t get an appointment during the busy pre-Thanksgiving season. She doesn’t recall whether the technician opened packaging that signals unused tools.

She put antibiotic ointment on the cut, but it didn’t heal after a few days. Eventually, the skin closed and a darkened bump formed. It was painful. She went to her doctor, who said it was a “callus from writing,” she told TODAY.com. But it was on her ring finger, which didn’t seem connected to writing. Her doctor said to keep an eye on it. 

Five months after the cut occurred, she mentioned it during a gynecology appointment and was referred to a dermatologist, who also advised keeping an eye on it. A wart developed. She went back to her primary care physician and then to another dermatologist. The spot was biopsied.

Squamous cell carcinoma is a common type of skin cancer, according to the American Academy of Dermatology. It can have many causes, but the cause in Ms. Garcia’s case was both very common and very rare: human papillomavirus, or HPV. HPV is a virus that infects millions of people every year, but it’s not a typical cause of skin cancer.

“It’s pretty rare for several reasons. Generally speaking, the strains that cause cancer from an HPV standpoint tend to be more sexually transmitted,” dermatologist Teo Soleymani told TODAY.com. “In Grace’s case, she had an injury, which became the portal of entry. So that thick skin that we have on our hands and feet that acts as a natural barrier against infections and things like that was no longer the case, and the virus was able to infect her skin.”

Dr. Soleymani said Ms. Garcia’s persistence to get answers likely saved her from losing a finger.

“Your outcomes are entirely dictated by how early you catch them, and very often they’re completely curable,” he said. “Her persistence – not only was she able to have a great outcome, she probably saved herself from having her finger amputated.”

SAN DIEGO – When patients ask if collagen supplements can benefit their skin, what should you tell them?

According to Ava Shamban, MD, a dermatologist who practices in Santa Monica, Calif., limited data exist to suggest that consuming collagen-dense foods can directly benefit skin or joint health. And in her opinion, more research is needed to establish knowledge of the effects and physiologic mechanism of collagen supplementation.

“Collagen is the most abundant protein in the skin; it is found only in animal flesh like meat and fish that contain connective tissue,” she said at the annual Masters of Aesthetics Symposium. “We produce less collagen as we age. External factors can slow down our collagen production, including smoking, sun exposure, lack of sleep/exercise, and alcohol consumption.”

Though human studies are lacking, some trials have found that collagen supplements may improve skin hydration and elasticity. “Maybe there’s some benefit, but the digestive process breaks collagen down into amino acids, so I don’t buy it,” she said.

At the meeting, Dr. Shamban discussed other topics related to the effect of supplements and nutrition on the skin:

Can Nutrafol reverse permanent hair loss? “It definitely doesn’t do that,” she said. “Can it help regrow hair? Perhaps.” Nutrafol is an over-the-counter supplement that aims to relieve moderate hair thinning or strengthen hair to prevent breakage, and is physician-formulated with medical-grade ingredients that target root causes of thinning such as stress, lifestyle, hormones, and nutrition.

As for biotin, “we now know that high levels of biotin can actually cause hair loss,” she said. “If you have advanced hair loss, supplements may not work for you. There is no hair regrowth supplement that can bring back a dead hair follicle. Can it help a miniaturized hair follicle? Maybe. Platelet-rich plasma injections have been shown to stimulate hair growth, but only if the follicle is miniaturized, not if it’s totally gone.”

How does the human microbiome affect skin? In a review of sequencing surveys of healthy adults, “the composition of microbial communities was found to be primarily dependent on the physiology of the skin site, with changes in the relative abundance of bacterial taxa associated with moist, dry, and sebaceous environments,” the authors reported . “The microbiome is the genetic material of all the microbes that live inside the body, including bacteria, fungi, protozoa, and viruses,” Dr. Shamban said. “The more diverse the microbiota is, the healthier it’s considered. That diversity is enriched through a diet full of various vegetables and fruits.”

Nearly all adults are colonized with Cutibacterium acnes (formerly Propionibacterium acnes), but only a minority have acne, which highlights the importance of studying diseases in the broader context of host genetics, immune or barrier defects, the microbiome, and the environment, she added. For example, the decreased diversity of the skin microbiome in people with atopic dermatitis has been linked to a reduction in environmental biodiversity in the areas surrounding their homes.

Do adaptogens have a role in skin care? Adaptogens such as ashwagandha, elderberry, ginseng, licorice root, neem, moringa, and reishi mushrooms have been used in Chinese and Ayurvedic medicine for centuries and are purported to promote adaptability, resilience, and survival of living organisms in stress. They appear to affect the neuroendocrine immune system and at low doses may function as mild stress mimetics.

“The idea is that combining adaptogens into skin care can reinforce and support the skin’s resistance against stressors that can accelerate visible signs of aging,” said Dr. Shamban. “They share some similarities with antioxidants in that their main purpose is to protect the body from external stressors such as UV rays, oxidation, and pollution.” More studies should be conducted to verify effectiveness, she said, “but Eastern practices that have incorporated it for centuries shouldn’t be fully dismissed. Most doctors believe adaptogens are safe, but how they interact with the mechanics of the body’s stress response system remains a mystery.”

Embrace the consumption of micronutrients. Inspired by work from dermatologist Zoe Diana Draelos, MD, Dr. Shamban advises patients to eat a “rainbow of different colored foods” every day, especially those rich in vitamins A, C, and E. Green foods are generally rich in vitamin E, brown foods are rich in trace minerals, and blue/purple foods are rich in antioxidants. “It’s always best to get nutrients from a rich, healthy diet, but sometimes our skin requires extra help,” she said.

A randomized, placebo-controlled, double-blind study by French researchers, which showed that skin is prone to seasonal changes during the winter, particularly in exposed areas, also looked at whether a daily micronutrient supplement with ingredients that included green tea extract, blackcurrant seed oil, and magnesium, had an impact on the negative effects of winter weather on the skin. “The data indicate that oral micronutrient supplementation can be a safe treatment, with no serious side effects, and may prevent or even eliminate the negative effects of winter on the skin,” she said.

Dr. Shamban disclosed that she conducts clinical trials for many pharmaceutical and device companies.

With the introduction of the first US Food and Drug Administration (FDA)–approved medication for alopecia areata (AA)—the Janus kinase (JAK) inhibitor, baricitinib—there is an important focus on this disease in the literature and for practicing dermatologists. Known by all as an autoimmune genetic disease that causes relapsing and remitting nonscarring hair loss, AA is a condition where the psychological burden has been less widely recognized. Patients with AA have reported lower health-related quality of life scores compared to patients with other skin conditions, including psoriasis or atopic dermatitis. In addition, a lesser amount of scalp coverage is negatively correlated to health-related quality of life scores.¹ Patients with AA also have a 39% lifetime prevalence of major depressive disorder and generalized anxiety disorder.² The treatment of AA has been a hodgepodge of topical, intralesional, and systemic agents, all with indirect immunosuppressive or anagen prolongation effects. Now that there is an approved therapy for AA with more treatments likely to be approved in the near future, there must be a focus on real-world outcomes. With the dawn of a new era in the treatment of AA as well as new information showcasing an altered prevalence of AA in skin of color, highlighting disparities among this population may help ease challenges dermatologic providers will face.

Efficacy of Baricitinib in Different Races and Ethnicities

How will patients of different races and ethnicities respond to this new treatment, and how will their emotional health be affected? The 2 phase 3 pivotal trials showing efficacy of baricitinib in AA included Black and Latino patients but not in a way that is representative of the US population.³ Until recently, the most commonly used prevalence of AA in the United States was from the NHANES I study completed between 1971 and 1974, which was between 0.1% and 0.2%⁴ with minimal focus on race and ethnicity. Recent studies suggest that there may be increased prevalence of this condition in Black patients in the United States. These new findings raise concern around access to care and treatment and the need to tailor psychosocial interventions for populations that may not currently have these supports.

A large cross-sectional study published in 2020 demonstrated that these data remained similar, with a lifetime prevalence of 0.21%.⁵ Of the 45,016 participants—representative of the US population based on the 2015 US Census—the average age of AA patients was 41.2 years, with 61.3% being White and not of Hispanic origin.⁵ In recent years, other studies have challenged the narrative that AA predominantly affects White patients.^6-8 A different cross-sectional study utilizing National Alopecia Areata Registry data from 2002 to 2016 suggested that Black patients have greater odds of developing AA.⁶ In this study of 2645 cases of AA, the odds ratios of developing the condition were 1.36 for Blacks, 0.53 for Asians, and 0.83 for Hispanics compared with the referent White population. These results were consistent through the varying subtypes of AA.⁶ In a reply to these findings, Gonzalez and Fleischer⁷ analyzed data from the 2007 to 2016 National Ambulatory Medical Care Survey database with a focus on racial and ethnic prevalence of AA. This study concluded that Latino and non-White individuals had an increased likelihood of clinician visits for AA compared with White individuals.⁷

More evidence of the Black predominance of AA was demonstrated in a study published in 2018. In this large-scale study, 63,960 women from the Nurses’ Health Study (NHS) and 88,368 women from the Nurses’ Health Study II (NHSII) were included to examine prevalence of disease among these US women.⁸ Analysis showed increased odds of AA based on self-reported race in Black and Hispanic women. Lifetime incidence of AA was greater in Black women, with 2.63 and 5.23 in NHS and NHSII, respectively. It was hypothesized that hairstyling practices in Black and Hispanic women may cause AA to be more noticeable,⁸ which may drive patients to seek medical evaluation.

Feaster and McMichael⁹ published information on the epidemiology of AA in a busy hair loss clinic. This retrospective single-institution study of 265 pediatric and adult Black patients with AA seen over a 5-year period showed that patients aged 18 to 34 years were most likely to present for care, which accounted for 35.8% of the study population, followed by patients aged 10 to 17 years, which accounted for 15.1%. This study also found that females were the larger segment of AA patients, with an increased distribution of disease in young patients. Most of these patients (68.2%) had patchy hair loss, and the ophiasis pattern was seen in 15.1%.⁹ Although the pathogenesis of AA is linked to autoimmunity,¹⁰ the leading cause for these epidemiologic findings of increased prevalence in Black patients is still uncertain.

Baricitinib for AA

In June 2022, the FDA announced the first biologic drug approved for the treatment of AA—baricitinib. Baricitinib is an oral, selective, reversible inhibitor of JAK1 and JAK2.³ The phase 3 trials for baricitinib—BRAVE-AA1 (N=654) and BRAVE-AA2 (N=546)—were conducted between March 2019 and May 2020. In these double-blind, parallel-group, randomized, placebo-controlled trials, 33% of the patient population receiving baricitinib accomplished 80% or more scalp coverage at 36 weeks. The Severity of Alopecia Tool (SALT) score also decreased to 20 or less in 36 weeks. The BRAVE-AA1 and BRAVE-AA2 trials consisted of a total of 1200 patients, with only 98 identifying as Black. Of these 98 patients, 33 were randomly selected to receive placebo.³ With studies now suggesting that Black individuals have greater odds of AA compared with White individuals⁶ and Black patients being more likely to seek medical care for AA,⁷ the BRAVE-AA1 and BRAVE-AA2 study population did not allow for significant comparative data for Black patients. These studies did not document Latino patient involvement.³ Future studies in AA must recruit a diversified group of study participants to better reflect the patients with an increased likelihood of presenting with AA.

Other Treatments on the Horizon

Baricitinib likely will remain alone in its class for only a short time. Phase 3 trials have been completed for ritlecitinib, brepocitinib, and deuruxolitinib for AA. Ritlecitinib, an irreversible inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, has met all end points in a phase 2b/3 study.¹¹ Brepocitinib is an oral tyrosine kinase 2/JAK1 inhibitor,¹² and deuruxolitinib is an investigational JAK1/2 inhibitor for AA.¹³

Prior authorizations have been the initial step for many drugs in varying fields of medical practice. A study completed in 2016 suggested that insurance coverage for biologics used in the treatment of psoriasis was becoming increasingly difficult.¹⁴ Prior authorization requirement rates increased from 16% of patients in 2009 to 75% in 2014. The decision time also increased from 3.7 days in 2009 to 6.7 days in 2014. The most common reason for delay in decisions and denials was due to step therapy.¹⁴ Insurance companies wanted many patients to try less expensive treatment options prior to “stepping up” to more expensive treatments. Although this may be the case in the treatment of psoriasis, the role of step therapy is unclear for patients with AA because there is only 1 FDA-approved medication. This sets out an ambiguous future for our patients with AA and approval for baricitinib.

The time required for the correspondence between insurance companies, clinic staff, and patients for drug approval may delay treatments, and not all providers have enough staff to coordinate and perform this work. For Black patients, who may present more frequently and with more severe disease,⁷ this could lead to a health care disparity due to the likelihood of the increased need for biologic treatment. Because Black patients have an increased likelihood of being uninsured or underinsured,¹⁵ this further decreases the chances of the most severe AA patients receiving the most helpful medication for their condition.

Many pharmaceutical companies have drug cost assistance programs that aim to provide support covering expensive medications for patients unable to afford them. Although this is a good first step, treatment with any JAK inhibitor potentially can be lifelong. Regarding the social determinants of health, it is known that access to medications does not solely depend on cost. Transportation and access to qualified health professionals are among the issues that create barriers to health care. Instilling long-term practices to ensure equal access to JAK inhibitors and treatment of AA may be the cornerstone to treating AA with equity. Whether we require pharmaceutical companies to make sure all patients have equal access to medications or provide community resources to hairstylists and federally qualified health centers, raising awareness and advocating for and creating attainable access to treatment modalities is imperative to providing well-rounded care to a diverse population.

Feaster and McMichael⁹ published information on the epidemiology of AA in a busy hair loss clinic. This retrospective single-institution study of 265 pediatric and adult Black patients with AA seen over a 5-year period showed that patients aged 18 to 34 years were most likely to present for care, which accounted for 35.8% of the study population, followed by patients aged 10 to 17 years, which accounted for 15.1%. This study also found that females were the larger segment of AA patients, with an increased distribution of disease in young patients. Most of these patients (68.2%) had patchy hair loss, and the ophiasis pattern was seen in 15.1%.⁹ Although the pathogenesis of AA is linked to autoimmunity,¹⁰ the leading cause for these epidemiologic findings of increased prevalence in Black patients is still uncertain.

Baricitinib for AA

In June 2022, the FDA announced the first biologic drug approved for the treatment of AA—baricitinib. Baricitinib is an oral, selective, reversible inhibitor of JAK1 and JAK2.³ The phase 3 trials for baricitinib—BRAVE-AA1 (N=654) and BRAVE-AA2 (N=546)—were conducted between March 2019 and May 2020. In these double-blind, parallel-group, randomized, placebo-controlled trials, 33% of the patient population receiving baricitinib accomplished 80% or more scalp coverage at 36 weeks. The Severity of Alopecia Tool (SALT) score also decreased to 20 or less in 36 weeks. The BRAVE-AA1 and BRAVE-AA2 trials consisted of a total of 1200 patients, with only 98 identifying as Black. Of these 98 patients, 33 were randomly selected to receive placebo.³ With studies now suggesting that Black individuals have greater odds of AA compared with White individuals⁶ and Black patients being more likely to seek medical care for AA,⁷ the BRAVE-AA1 and BRAVE-AA2 study population did not allow for significant comparative data for Black patients. These studies did not document Latino patient involvement.³ Future studies in AA must recruit a diversified group of study participants to better reflect the patients with an increased likelihood of presenting with AA.

Other Treatments on the Horizon

Baricitinib likely will remain alone in its class for only a short time. Phase 3 trials have been completed for ritlecitinib, brepocitinib, and deuruxolitinib for AA. Ritlecitinib, an irreversible inhibitor of JAK3 and the tyrosine kinase expressed in hepatocellular carcinoma (TEC) kinase family, has met all end points in a phase 2b/3 study.¹¹ Brepocitinib is an oral tyrosine kinase 2/JAK1 inhibitor,¹² and deuruxolitinib is an investigational JAK1/2 inhibitor for AA.¹³

Prior authorizations have been the initial step for many drugs in varying fields of medical practice. A study completed in 2016 suggested that insurance coverage for biologics used in the treatment of psoriasis was becoming increasingly difficult.¹⁴ Prior authorization requirement rates increased from 16% of patients in 2009 to 75% in 2014. The decision time also increased from 3.7 days in 2009 to 6.7 days in 2014. The most common reason for delay in decisions and denials was due to step therapy.¹⁴ Insurance companies wanted many patients to try less expensive treatment options prior to “stepping up” to more expensive treatments. Although this may be the case in the treatment of psoriasis, the role of step therapy is unclear for patients with AA because there is only 1 FDA-approved medication. This sets out an ambiguous future for our patients with AA and approval for baricitinib.

The time required for the correspondence between insurance companies, clinic staff, and patients for drug approval may delay treatments, and not all providers have enough staff to coordinate and perform this work. For Black patients, who may present more frequently and with more severe disease,⁷ this could lead to a health care disparity due to the likelihood of the increased need for biologic treatment. Because Black patients have an increased likelihood of being uninsured or underinsured,¹⁵ this further decreases the chances of the most severe AA patients receiving the most helpful medication for their condition.

Many pharmaceutical companies have drug cost assistance programs that aim to provide support covering expensive medications for patients unable to afford them. Although this is a good first step, treatment with any JAK inhibitor potentially can be lifelong. Regarding the social determinants of health, it is known that access to medications does not solely depend on cost. Transportation and access to qualified health professionals are among the issues that create barriers to health care. Instilling long-term practices to ensure equal access to JAK inhibitors and treatment of AA may be the cornerstone to treating AA with equity. Whether we require pharmaceutical companies to make sure all patients have equal access to medications or provide community resources to hairstylists and federally qualified health centers, raising awareness and advocating for and creating attainable access to treatment modalities is imperative to providing well-rounded care to a diverse population.

With the introduction of the first US Food and Drug Administration (FDA)–approved medication for alopecia areata (AA)—the Janus kinase (JAK) inhibitor, baricitinib—there is an important focus on this disease in the literature and for practicing dermatologists. Known by all as an autoimmune genetic disease that causes relapsing and remitting nonscarring hair loss, AA is a condition where the psychological burden has been less widely recognized. Patients with AA have reported lower health-related quality of life scores compared to patients with other skin conditions, including psoriasis or atopic dermatitis. In addition, a lesser amount of scalp coverage is negatively correlated to health-related quality of life scores.¹ Patients with AA also have a 39% lifetime prevalence of major depressive disorder and generalized anxiety disorder.² The treatment of AA has been a hodgepodge of topical, intralesional, and systemic agents, all with indirect immunosuppressive or anagen prolongation effects. Now that there is an approved therapy for AA with more treatments likely to be approved in the near future, there must be a focus on real-world outcomes. With the dawn of a new era in the treatment of AA as well as new information showcasing an altered prevalence of AA in skin of color, highlighting disparities among this population may help ease challenges dermatologic providers will face.

Efficacy of Baricitinib in Different Races and Ethnicities

How will patients of different races and ethnicities respond to this new treatment, and how will their emotional health be affected? The 2 phase 3 pivotal trials showing efficacy of baricitinib in AA included Black and Latino patients but not in a way that is representative of the US population.³ Until recently, the most commonly used prevalence of AA in the United States was from the NHANES I study completed between 1971 and 1974, which was between 0.1% and 0.2%⁴ with minimal focus on race and ethnicity. Recent studies suggest that there may be increased prevalence of this condition in Black patients in the United States. These new findings raise concern around access to care and treatment and the need to tailor psychosocial interventions for populations that may not currently have these supports.

A large cross-sectional study published in 2020 demonstrated that these data remained similar, with a lifetime prevalence of 0.21%.⁵ Of the 45,016 participants—representative of the US population based on the 2015 US Census—the average age of AA patients was 41.2 years, with 61.3% being White and not of Hispanic origin.⁵ In recent years, other studies have challenged the narrative that AA predominantly affects White patients.^6-8 A different cross-sectional study utilizing National Alopecia Areata Registry data from 2002 to 2016 suggested that Black patients have greater odds of developing AA.⁶ In this study of 2645 cases of AA, the odds ratios of developing the condition were 1.36 for Blacks, 0.53 for Asians, and 0.83 for Hispanics compared with the referent White population. These results were consistent through the varying subtypes of AA.⁶ In a reply to these findings, Gonzalez and Fleischer⁷ analyzed data from the 2007 to 2016 National Ambulatory Medical Care Survey database with a focus on racial and ethnic prevalence of AA. This study concluded that Latino and non-White individuals had an increased likelihood of clinician visits for AA compared with White individuals.⁷

More evidence of the Black predominance of AA was demonstrated in a study published in 2018. In this large-scale study, 63,960 women from the Nurses’ Health Study (NHS) and 88,368 women from the Nurses’ Health Study II (NHSII) were included to examine prevalence of disease among these US women.⁸ Analysis showed increased odds of AA based on self-reported race in Black and Hispanic women. Lifetime incidence of AA was greater in Black women, with 2.63 and 5.23 in NHS and NHSII, respectively. It was hypothesized that hairstyling practices in Black and Hispanic women may cause AA to be more noticeable,⁸ which may drive patients to seek medical evaluation.
