Alopecia areata (AA) affects 4.5 million individuals in the United States, with 66% younger than 30 years.^1,2 Inflammation causes hair loss in well-circumscribed, nonscarring patches on the body with a predilection for the scalp.^3-6 The disease can devastate a patient’s self-esteem, in turn reducing quality of life.^1,7 Alopecia areata is an autoimmune T-cell–mediated disease in which hair follicles lose their immune privilege.^8-10 Several specific mechanisms in the cytokine interactions between T cells and the hair follicle have been discovered, revealing the Janus kinase–signal transducer and activator of transcription (JAK-STAT) pathway as pivotal in the pathogenesis of the disease and leading to the use of JAK inhibitors for treatment.¹¹

There is no cure for AA, and the condition is managed with prolonged medical treatments and cosmetic therapies.² Although some patients may be able to manage the annual cost, the cumulative cost of AA treatment can be burdensome.¹² This cumulative cost may increase if newer, potentially expensive treatments become the standard of care. Patients with AA report dipping into their savings (41.3%) and cutting back on food or clothing expenses (33.9%) to account for the cost of alopecia treatment. Although prior estimates of the annual out-of-pocket cost of AA treatments range from $1354 to $2685, the cost burden of individual therapies is poorly understood.^12-14

Patients who must juggle expensive medical bills with basic living expenses may be lost to follow-up or fall into treatment nonadherence.¹⁵ Other patients’ out-of-pocket costs may be manageable, but the costs to the health care system may compromise care in other ways. We conducted a literature review of the recommended therapies for AA based on American Academy of Dermatology (AAD) guidelines to identify the costs of alopecia treatment and consolidate the available data for the practicing dermatologist.

Methods

We conducted a PubMed search of articles indexed for MEDLINE through September 15, 2022, using the terms alopecia and cost plus one of the treatments (n=21) identified by the AAD² for the treatment of AA (Figure). The reference lists of included articles were reviewed to identify other potentially relevant studies. Forty-five articles were identified.

Given the dearth of cost research in alopecia and the paucity of large prospective studies, we excluded articles that were not available in their full-text form or were not in English (n=3), articles whose primary study topic was not AA or an expert-approved alopecia treatment (n=15), and articles with no concrete cost data (n=17), which yielded 10 relevant articles that we studied using qualitative analysis.

Due to substantial differences in study methods and outcome measures, we did not compare the costs of alopecia among studies and did not perform statistical analysis. The quality of each study was investigated and assigned a level of evidence per the 2009 criteria from the Centre for Evidence-Based Medicine.¹⁶

All cost data were converted into US dollars ($) using the conversion rate from the time of the original article’s publication.

Results

Total and Out-of-pocket Costs of AA—Li et al¹³ studied out-of-pocket health care costs for AA patients (N=675). Of these participants, 56.9% said their AA was moderately to seriously financially burdensome, and 41.3% reported using their savings to manage these expenses. Participants reported median out-of-pocket spending of $1354 (interquartile range, $537–$3300) annually. The most common categories of expenses were hair appointments (81.8%) and vitamins/supplements (67.7%).¹³

Mesinkovska et al¹⁴ studied the qualitative and quantitative financial burdens of moderate to severe AA (N=216). Fifty-seven percent of patients reported the financial impact of AA as moderately to severely burdensome with a willingness to borrow money or use savings to cover out-of-pocket costs. Patients without insurance cited cost as a major barrier to obtaining reatment. In addition to direct treatment-related expenses, AA patients spent a mean of $1961 per year on therapy to cope with the disease’s psychological burden. Lost work hours represented another source of financial burden; 61% of patients were employed, and 45% of them reported missing time from their job because of AA.¹⁴

Mostaghimi et al¹² studied health care resource utilization and all-cause direct health care costs in privately insured AA patients with or without alopecia totalis (AT) or alopecia universalis (AU)(n=14,972) matched with non-AA controls (n=44,916)(1:3 ratio). Mean total all-cause medical and pharmacy costs were higher in both AA groups compared with controls (AT/AU, $18,988 vs $11,030; non-AT/AU, $13,686 vs $9336; P<.001 for both). Out-of-pocket costs were higher for AA vs controls (AT/AU, $2685 vs $1457; non-AT/AU, $2223 vs $1341; P<.001 for both). Medical costs in the AT/AU and non-AT/AU groups largely were driven by outpatient costs (AT/AU, $10,277 vs $5713; non-AT/AU, $8078 vs $4672; P<.001 for both).¹²

Costs of Concealment—When studying the out-of-pocket costs of AA (N=675), Li et al¹³ discovered that the median yearly spending was highest on headwear or cosmetic items such as hats, wigs, and makeup ($450; interquartile range, $50–$1500). Mesinkovska et al¹⁴ reported that 49% of patients had insurance that covered AA treatment. However, 75% of patients reported that their insurance would not cover costs of concealment (eg, weave, wig, hair piece). Patients (N=112) spent a mean of $2211 per year and 10.3 hours per week on concealment.¹⁴

Minoxidil—Minoxidil solution is available over-the-counter, and its ease of access makes it a popular treatment for AA.¹⁷ Because manufacturers can sell directly to the public, minoxidil is marketed with bold claims and convincing packaging. Shrank¹⁸ noted that the product can take 4 months to work, meaning customers must incur a substantial cost burden before realizing the treatment’s benefit, which is not always obvious when purchasing minoxidil products, leaving customers—who were marketed a miracle drug—disappointed. Per Shrank,¹⁸ patients who did not experience hair regrowth after 4 months were advised to continue treatment for a year, leading them to spend hundreds of dollars for uncertain results. Those who did experience hair regrowth were advised to continue using the product twice daily 7 days per week indefinitely.¹⁸

Wehner et al¹⁹ studied the association between gender and drug cost for over-the-counter minoxidil. The price that women paid for 2% regular-strength minoxidil solutions was similar to the price that men paid for 5% extra-strength minoxidil solutions (women’s 2%, $7.63/30 mL; men’s 5%, $7.61/30 mL; P=.67). Minoxidil 5% foams with identical ingredients were priced significantly more per volume of the same product when sold as a product directed at women vs a product directed at men (men’s 5%, $8.05/30 mL; women’s 5%, $11.27/30 mL; P<.001).¹⁹

Beach²⁰ compared the cost of oral minoxidil to topical minoxidil. At $28.60 for a 3-month supply, oral minoxidil demonstrated cost savings compared to topical minoxidil ($48.30).²⁰

Diphencyprone—Bhat et al²¹ studied the cost-efficiency of diphencyprone (DPC) in patients with AA resistant to at least 2 conventional treatments (N=29). After initial sensitization with 2% DPC, patients received weekly or fortnightly treatments. Most of the annual cost burden of DPC treatment was due to staff time and overhead rather than the cost of the DPC itself: $258 for the DPC, $978 in staff time and overhead for the department, and $1233 directly charged to the patient.²¹

Lekhavat et al²² studied the economic impact of home-use vs office-use DPC in extensive AA (N=82). Both groups received weekly treatments in the hospital until DPC concentrations had been adjusted. Afterward, the home group was given training on self-applying DPC at home. The home group had monthly office visits for DPC concentration evaluation and refills, while the office group had weekly appointments for DPC treatment at the hospital. Calculated costs included those to the health care provider (ie, material, labor, capital costs) and the patient’s final out-of-pocket expense. The total cost to the health care provider was higher for the office group than the home group at 48 weeks (office, $683.52; home, $303.67; P<.001). Median out-of-pocket costs did not vary significantly between groups, which may have been due to small sample size affecting the range (office, $418.07; home, $189.69; P=.101). There was no significant difference between groups in the proportion of patients who responded favorably to the DPC.²²

JAK Inhibitors—Chen et al²³ studied the efficacy of low-dose (5 mg) tofacitinib to treat severe AA (N=6). Compared to prior studies,^24-27 this analysis reported the efficacy of low-dose tofacitinib was not inferior to higher doses (10–20 mg), and low-dose tofacitinib reduced treatment costs by more than 50%.²³

Per the GlobalData Healthcare database, the estimated annual cost of therapy for JAK inhibitors following US Food and Drug Administration approval was $50,000. At the time of their reporting, the next most expensive immunomodulatory drug for AA was cyclosporine, with an annual cost of therapy of $1400.²⁸ Dillon²⁹ reviewed the use of JAK inhibitors for the treatment of AA. The cost estimates by Dillon²⁹ prior to FDA approval aligned with the pricing of Eli Lilly and Company for the now-approved JAK inhibitor baricitinib.³⁰ The list price of baricitinib is $2739.99 for a 30-day supply of 2-mg tablets or $5479.98 for a 30-day supply of 4-mg tablets. This amounts to $32,879.88 for an annual supply of 2-mg tablets and $65,759.76 for an annual supply for 4-mg tablets, though the out-of-pocket costs will vary.³⁰

Comment

We reviewed the global and treatment-specific costs of AA, consolidating the available data for the practicing dermatologist. Ten studies of approximately 16,000 patients with AA across a range of levels of evidence (1a to 4) were included (Table). Three of 10 articles studied global costs of AA, 1 studied costs of concealment, 3 studied costs of minoxidil, 2 studied costs of DPC, and 2 studied costs of JAK inhibitors. Only 2 studies achieved level of evidence 1a: the first assessed the economic impact of home-use vs office-use DPC,²² and the second researched the efficacy and outcomes of JAK inhibitors.²⁹

Hair-loss treatments and concealment techniques cost the average patient thousands of dollars. Spending was highest on headwear or cosmetic items, which were rarely covered by insurance.¹³ Psychosocial sequelae further increased cost via therapy charges and lost time at work.¹⁴ Patients with AA had greater all-cause medical costs than those without AA, with most of the cost driven by outpatient visits. Patients with AA also paid nearly twice as much as non-AA patients on out-of-pocket health care expenses.¹⁴ Despite the high costs and limited efficacy of many AA therapies, patients reported willingness to incur debt or use savings to manage their AA. This willingness to pay reflects AA’s impact on quality of life and puts these patients at high risk for financial distress.¹³

Minoxidil solution does not require physician office visits and is available over-the-counter.¹⁷ Despite identical ingredients, minoxidil is priced more per volume when marketed to women compared with men, which reflects the larger issue of gender-based pricing that does not exist for other AAD-approved alopecia therapies but may exist for cosmetic treatments and nonapproved therapies (eg, vitamins/supplements) that are popular in the treatment of AA.¹⁹ Oral minoxidil was more cost-effective than the topical form, and gender-based pricing was a nonissue.²⁰ However, oral minoxidil requires a prescription, mandating patients incur the cost of an office visit. Patients should be wary of gender- or marketing-related surcharges for minoxidil solutions, and oral minoxidil may be a cost-effective choice.

Diphencyprone is a relatively affordable drug for AA, but the regular office visits traditionally required for its administration increase associated cost.²¹ Self-administration of DPC at home was more cost- and time-effective than in-office DPC administration and did not decrease efficacy. A regimen combining office visits for initial DPC titration, at-home DPC administration, and periodic office follow-up could minimize costs while preserving outcomes and safety.²²

Janus kinase inhibitors are cutting-edge and expensive therapies for AA. The annual cost of these medications poses a tremendous burden on the payer (list price of annual supply ritlecitinib is $49,000),³¹ be that the patient or the insurance company. Low-dose tofacitinib may be similarly efficacious and could substantially reduce treatment costs.²³ The true utility of these medications, specifically considering their steep costs, remains to be determined.

Conclusion

Alopecia areata poses a substantial and recurring cost burden on patients that is multifactorial including treatment, office visits, concealment, alternative therapies, psychosocial costs, and missed time at work. Although several treatment options exist, none of them are definitive. Oral minoxidil and at-home DPC administration can be cost-effective, though the cumulative cost is still high. The cost utility of JAK inhibitors remains unclear. When JAK inhibitors are prescribed, low-dose therapy may be used as maintenance to curb treatment costs. Concealment and therapy costs pose an additional, largely out-of-pocket financial burden. Despite the limited efficacy of many AA therapies, patients incur substantial expenses to manage their AA. This willingness to pay reflects AA’s impact on quality of life and puts these patients at high risk for financial distress. There are no head-to-head studies comparing the cost-effectiveness of the different AA therapies; thus, it is unclear if one treatment is most efficacious. This topic remains an avenue for future investigation. Much of the cost burden of AA treatment falls directly on patients. Increasing coverage of AA-associated expenses, such as minoxidil therapy or wigs, could decrease the cost burden on patients. Providers also can inform patients about cost-saving tactics, such as purchasing minoxidil based on concentration and vehicle rather than marketing directed at men vs women. Finally, some patients may have insurance plans that at least partially cover the costs of wigs but may not be aware of this benefit. Querying a patient’s insurance provider can further minimize costs.

In addition to direct treatment-related expenses, AA patients spent a mean of $1961 per year on therapy to cope with the disease’s psychological burden. Lost work hours represented another source of financial burden; 61% of patients were employed, and 45% of them reported missing time from their job because of AA.¹⁴

Mostaghimi et al¹² studied health care resource utilization and all-cause direct health care costs in privately insured AA patients with or without alopecia totalis (AT) or alopecia universalis (AU)(n=14,972) matched with non-AA controls (n=44,916)(1:3 ratio). Mean total all-cause medical and pharmacy costs were higher in both AA groups compared with controls (AT/AU, $18,988 vs $11,030; non-AT/AU, $13,686 vs $9336; P<.001 for both). Out-of-pocket costs were higher for AA vs controls (AT/AU, $2685 vs $1457; non-AT/AU, $2223 vs $1341; P<.001 for both). Medical costs in the AT/AU and non-AT/AU groups largely were driven by outpatient costs (AT/AU, $10,277 vs $5713; non-AT/AU, $8078 vs $4672; P<.001 for both).¹²

Costs of Concealment—When studying the out-of-pocket costs of AA (N=675), Li et al¹³ discovered that the median yearly spending was highest on headwear or cosmetic items such as hats, wigs, and makeup ($450; interquartile range, $50–$1500). Mesinkovska et al¹⁴ reported that 49% of patients had insurance that covered AA treatment. However, 75% of patients reported that their insurance would not cover costs of concealment (eg, weave, wig, hair piece). Patients (N=112) spent a mean of $2211 per year and 10.3 hours per week on concealment.¹⁴

Minoxidil—Minoxidil solution is available over-the-counter, and its ease of access makes it a popular treatment for AA.¹⁷ Because manufacturers can sell directly to the public, minoxidil is marketed with bold claims and convincing packaging. Shrank¹⁸ noted that the product can take 4 months to work, meaning customers must incur a substantial cost burden before realizing the treatment’s benefit, which is not always obvious when purchasing minoxidil products, leaving customers—who were marketed a miracle drug—disappointed. Per Shrank,¹⁸ patients who did not experience hair regrowth after 4 months were advised to continue treatment for a year, leading them to spend hundreds of dollars for uncertain results. Those who did experience hair regrowth were advised to continue using the product twice daily 7 days per week indefinitely.¹⁸

Wehner et al¹⁹ studied the association between gender and drug cost for over-the-counter minoxidil. The price that women paid for 2% regular-strength minoxidil solutions was similar to the price that men paid for 5% extra-strength minoxidil solutions (women’s 2%, $7.63/30 mL; men’s 5%, $7.61/30 mL; P=.67). Minoxidil 5% foams with identical ingredients were priced significantly more per volume of the same product when sold as a product directed at women vs a product directed at men (men’s 5%, $8.05/30 mL; women’s 5%, $11.27/30 mL; P<.001).¹⁹

Beach²⁰ compared the cost of oral minoxidil to topical minoxidil. At $28.60 for a 3-month supply, oral minoxidil demonstrated cost savings compared to topical minoxidil ($48.30).²⁰

Diphencyprone—Bhat et al²¹ studied the cost-efficiency of diphencyprone (DPC) in patients with AA resistant to at least 2 conventional treatments (N=29). After initial sensitization with 2% DPC, patients received weekly or fortnightly treatments. Most of the annual cost burden of DPC treatment was due to staff time and overhead rather than the cost of the DPC itself: $258 for the DPC, $978 in staff time and overhead for the department, and $1233 directly charged to the patient.²¹

Lekhavat et al²² studied the economic impact of home-use vs office-use DPC in extensive AA (N=82). Both groups received weekly treatments in the hospital until DPC concentrations had been adjusted. Afterward, the home group was given training on self-applying DPC at home. The home group had monthly office visits for DPC concentration evaluation and refills, while the office group had weekly appointments for DPC treatment at the hospital. Calculated costs included those to the health care provider (ie, material, labor, capital costs) and the patient’s final out-of-pocket expense. The total cost to the health care provider was higher for the office group than the home group at 48 weeks (office, $683.52; home, $303.67; P<.001). Median out-of-pocket costs did not vary significantly between groups, which may have been due to small sample size affecting the range (office, $418.07; home, $189.69; P=.101). There was no significant difference between groups in the proportion of patients who responded favorably to the DPC.²²

JAK Inhibitors—Chen et al²³ studied the efficacy of low-dose (5 mg) tofacitinib to treat severe AA (N=6). Compared to prior studies,^24-27 this analysis reported the efficacy of low-dose tofacitinib was not inferior to higher doses (10–20 mg), and low-dose tofacitinib reduced treatment costs by more than 50%.²³

Per the GlobalData Healthcare database, the estimated annual cost of therapy for JAK inhibitors following US Food and Drug Administration approval was $50,000. At the time of their reporting, the next most expensive immunomodulatory drug for AA was cyclosporine, with an annual cost of therapy of $1400.²⁸ Dillon²⁹ reviewed the use of JAK inhibitors for the treatment of AA. The cost estimates by Dillon²⁹ prior to FDA approval aligned with the pricing of Eli Lilly and Company for the now-approved JAK inhibitor baricitinib.³⁰ The list price of baricitinib is $2739.99 for a 30-day supply of 2-mg tablets or $5479.98 for a 30-day supply of 4-mg tablets. This amounts to $32,879.88 for an annual supply of 2-mg tablets and $65,759.76 for an annual supply for 4-mg tablets, though the out-of-pocket costs will vary.³⁰

Comment

We reviewed the global and treatment-specific costs of AA, consolidating the available data for the practicing dermatologist. Ten studies of approximately 16,000 patients with AA across a range of levels of evidence (1a to 4) were included (Table). Three of 10 articles studied global costs of AA, 1 studied costs of concealment, 3 studied costs of minoxidil, 2 studied costs of DPC, and 2 studied costs of JAK inhibitors. Only 2 studies achieved level of evidence 1a: the first assessed the economic impact of home-use vs office-use DPC,²² and the second researched the efficacy and outcomes of JAK inhibitors.²⁹

Hair-loss treatments and concealment techniques cost the average patient thousands of dollars. Spending was highest on headwear or cosmetic items, which were rarely covered by insurance.¹³ Psychosocial sequelae further increased cost via therapy charges and lost time at work.¹⁴ Patients with AA had greater all-cause medical costs than those without AA, with most of the cost driven by outpatient visits. Patients with AA also paid nearly twice as much as non-AA patients on out-of-pocket health care expenses.¹⁴ Despite the high costs and limited efficacy of many AA therapies, patients reported willingness to incur debt or use savings to manage their AA. This willingness to pay reflects AA’s impact on quality of life and puts these patients at high risk for financial distress.¹³

Minoxidil solution does not require physician office visits and is available over-the-counter.¹⁷ Despite identical ingredients, minoxidil is priced more per volume when marketed to women compared with men, which reflects the larger issue of gender-based pricing that does not exist for other AAD-approved alopecia therapies but may exist for cosmetic treatments and nonapproved therapies (eg, vitamins/supplements) that are popular in the treatment of AA.¹⁹ Oral minoxidil was more cost-effective than the topical form, and gender-based pricing was a nonissue.²⁰ However, oral minoxidil requires a prescription, mandating patients incur the cost of an office visit. Patients should be wary of gender- or marketing-related surcharges for minoxidil solutions, and oral minoxidil may be a cost-effective choice.

Diphencyprone is a relatively affordable drug for AA, but the regular office visits traditionally required for its administration increase associated cost.²¹ Self-administration of DPC at home was more cost- and time-effective than in-office DPC administration and did not decrease efficacy. A regimen combining office visits for initial DPC titration, at-home DPC administration, and periodic office follow-up could minimize costs while preserving outcomes and safety.²²

Janus kinase inhibitors are cutting-edge and expensive therapies for AA. The annual cost of these medications poses a tremendous burden on the payer (list price of annual supply ritlecitinib is $49,000),³¹ be that the patient or the insurance company. Low-dose tofacitinib may be similarly efficacious and could substantially reduce treatment costs.²³ The true utility of these medications, specifically considering their steep costs, remains to be determined.

Conclusion

Alopecia areata poses a substantial and recurring cost burden on patients that is multifactorial including treatment, office visits, concealment, alternative therapies, psychosocial costs, and missed time at work. Although several treatment options exist, none of them are definitive. Oral minoxidil and at-home DPC administration can be cost-effective, though the cumulative cost is still high. The cost utility of JAK inhibitors remains unclear. When JAK inhibitors are prescribed, low-dose therapy may be used as maintenance to curb treatment costs. Concealment and therapy costs pose an additional, largely out-of-pocket financial burden. Despite the limited efficacy of many AA therapies, patients incur substantial expenses to manage their AA. This willingness to pay reflects AA’s impact on quality of life and puts these patients at high risk for financial distress. There are no head-to-head studies comparing the cost-effectiveness of the different AA therapies; thus, it is unclear if one treatment is most efficacious. This topic remains an avenue for future investigation. Much of the cost burden of AA treatment falls directly on patients. Increasing coverage of AA-associated expenses, such as minoxidil therapy or wigs, could decrease the cost burden on patients. Providers also can inform patients about cost-saving tactics, such as purchasing minoxidil based on concentration and vehicle rather than marketing directed at men vs women. Finally, some patients may have insurance plans that at least partially cover the costs of wigs but may not be aware of this benefit. Querying a patient’s insurance provider can further minimize costs.

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.

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.
