Frontal fibrosing alopecia (FFA) is a lymphocytic cicatricial alopecia that primarily affects postmenopausal women. Considered a subtype of lichen planopilaris (LPP), FFA is histologically identical but presents as symmetric frontotemporal hairline recession rather than the multifocal distribution typical of LPP (Figure 1). Patients also may experience symptoms such as itching, facial papules, and eyebrow loss. As a progressive and scarring alopecia, early management of FFA is necessary to prevent permanent hair loss; however, there still are no clear guidelines regarding the efficacy of different treatment options for FFA due to a lack of randomized controlled studies in the literature. Patients with skin of color (SOC) also may have varying responses to treatment, further complicating the establishment of any treatment algorithm. Furthermore, symptoms, clinical findings, and demographics of FFA have been observed to vary across different ethnicities, especially among Black individuals. We conducted a systematic review of the literature on FFA in Black patients, with an analysis of demographics, clinical findings, concomitant skin conditions, treatments given, and treatment responses.

Methods

A PubMed search of articles indexed for MEDLINE was conducted of studies investigating FFA in patients with SOC from January 1, 2000, through November 30, 2020, using the terms frontal fibrosing alopecia, ethnicity, African, Black, Asian, Indian, Hispanic, and Latino. Articles were included if they were available in English and discussed treatment and clinical outcomes of FFA in Black individuals. The reference lists of included studies also were reviewed. Articles were assessed for quality of evidence using a 4-point scale (1=well-designed randomized controlled trials; 2=controlled trials with limitations or well-designed cohort or case-control studies; 3=case series with or without intervention; 4=case reports). Variables related to study type, patient demographics, treatments, and clinical outcomes were recorded.

Results

Of the 69 search results, 8 studies—2 retrospective cohort studies, 3 case series, and 3 case reports—describing 51 Black individuals with FFA were included in our review (eTable). Of these, 49 (96.1%) were female and 2 (3.9%) were male. Of the 45 females with data available for menopausal status, 24 (53.3%) were premenopausal and 21 (46.7%) were postmenopausal; data were not available for 4 females. Patients identified as African or African American in 27 (52.9%) cases, South African in 19 (37.3%), Black in 3 (5.9%), Indian in 1 (2.0%), and Afro-Caribbean in 1 (2.0%). The average age of FFA onset was 43.8 years in females (raw data available in 24 patients) and 35 years in males (raw data available in 2 patients). A family history of hair loss was reported in 15.7% (8/51) of patients.

Involved areas of hair loss included the frontotemporal hairline (51/51 [100%]), eyebrows (32/51 [62.7%]), limbs (4/51 [7.8%]), occiput (4/51 [7.8%]), facial hair (2/51 [3.9%]), vertex scalp (1/51 [2.0%]), and eyelashes (1/51 [2.0%]). Patchy alopecia suggestive of LPP was reported in 2 (3.9%) patients.

Patients frequently presented with scalp pruritus (26/51 [51.0%]), perifollicular papules or pustules (9/51 [17.6%]), and perifollicular hyperpigmentation (9/51 [17.6%]). Other associated symptoms included perifollicular erythema (6/51 [11.8%]), scalp pain (5/51 [9.8%]), hyperkeratosis or flaking (3/51 [5.9%]), and facial papules (2/51 [3.9%]). Loss of follicular ostia, prominent follicular ostia, and the lonely hair sign (Figure 2) was described in 21 (41.2%), 5 (9.8%), and 15 (29.4%) of patients, respectively. Hairstyles that involve scalp traction (19/51 [37.3%]) and/or chemicals (28/51 [54.9%]), such as hair dye or chemical relaxers, commonly were reported in patients prior to the onset of FFA.

The most commonly reported dermatologic comorbidities included traction alopecia (17/51 [33.3%]), followed by lichen planus pigmentosus (LLPigm)(7/51 [13.7%]), LPP (2/51 [3.9%]), psoriasis (1/51 [2.0%]), and morphea (1/51 [2.0%]). Reported comorbid diseases included Sjögren syndrome (2/51 [3.9%]), hypothyroidism (2/51 [3.9%]), HIV (1/51 [2.0%]), and diabetes mellitus (1/51 [2.0%]).

Of available reports (n=32), the most common histologic findings included perifollicular fibrosis (23/32 [71.9%]), lichenoid lymphocytic inflammation (22/23 [95.7%]) primarily affecting the isthmus and infundibular areas of the follicles, and decreased follicular density (21/23 [91.3%]).

 

 

The average time interval from treatment initiation to treatment assessment in available reports (n=25) was 1.8 years (range, 0.5–2 years). Response to treatment included regrowth of hair in 5.9% (3/51) of patients, FFA stabilization in 39.2% (20/51), FFA progression in 51.0% (26/51), and not reported in 3.9% (2/51). Combination therapy was used in 84.3% (43/51) of patients, while monotherapy was used in 11.8% (6/51), and 3.9% (2/51) did not have any treatment reported. Response to treatment was highly variable among patients, as were the combinations of therapeutic agents used (Table). Regrowth of hair was rare, occurring in only 2 (100%) patients treated with oral prednisone plus hydroxychloroquine (HCQ) or chloroquine (CHQ), and in 1 (50.0%) patient treated with topical corticosteroids plus antifungal shampoo, while there was no response in the other patient treated with this combination.

Treatment Response in Black Patients With FFA (N=51)

Improvement in hair loss, defined as having at least slowed progression of FFA, was observed in 100% (2/2) of patients who had oral steroids as part of their treatment regimen, followed by 5-alpha-reductase inhibitors (5-ARIs)(finasteride and dutasteride; 62.5% [5/8]), intralesional steroids (57.1% [8/14]), HCQ/CHQ (42.9% [15/35]), topical steroids (41.5% [17/41]), antifungal shampoo (40.0% [2/5]), topical/oral minoxidil (36.0% [9/25]), and tacrolimus (33.3% [7/21]).

Comment

Frontal fibrosing alopecia is a progressive scarring alopecia and a clinical variant of LPP. First described in 1994 by Kossard,1 it initially was thought to be a disease of postmenopausal White women. Although still most prevalent in White individuals, there has been a growing number of reports describing FFA in patients with SOC, including Black individuals.10 Despite the increasing number of cases over the years, studies on the treatment of FFA remain sparse. Without expert guidelines, treatments usually are chosen based on clinician preferences. Few observational studies on these treatment modalities and their clinical outcomes exist, and the cohorts largely are composed of White patients.10-12 However, Black individuals may respond differently to these treatments, just as they have been shown to exhibit unique features of FFA.3

Demographics of Patients With FFA—Consistent with our findings, prior studies have found that Black patients are more likely to be younger and premenopausal at FFA onset than their White counterparts.13-15 Among the Black individuals included in our review, the majority were premenopausal (53%) with an average age of FFA onset of 46.7 years. Conversely, only 5% of 60 White females with FFA reported in a retrospective review were premenopausal and had an older mean age of FFA onset of 64 years,1 substantiating prior reports.

Clinical Findings in Patients With FFA—The clinical findings observed in our cohort were consistent with what has previously been described in Black patients, including loss of follicular ostia (41.2%), lonely hair sign (29.4%), perifollicular erythema (11.8%), perifollicular papules (17.6%), and hyperkeratosis or flaking (5.9%). In comparing these findings with a review of 932 patients, 86% of whom were White, the observed frequencies of follicular ostia loss (38.3%) and lonely hair sign (26.7%) were similar; however, perifollicular erythema (44.2%), and hyperkeratosis (44.4%) were more prevalent in this group, while perifollicular papules (6.2%) were less common compared to our Black cohort.16 An explanation for this discrepancy in perifollicular erythema may be the increased skin pigmentation diminishing the appearance of erythema in Black individuals. Our cohort of Black individuals noted the presence of follicular hyperpigmentation (17.6%) and a high prevalence of scalp pruritus (51.0%), which appear to be more common in Black patients.3,17 Although it is unclear why these differences in FFA presentation exist, it may be helpful for clinicians to be aware of these unique features when examining Black patients with suspected FFA.

Concomitant Cutaneous Disorders—A notable proportion of our cohort also had concomitant traction alopecia, which presents with frontotemporal alopecia, similar to FFA, making the diagnosis more challenging; however, the presence of perifollicular hyperpigmentation and facial hyperpigmentation in FFA may aid in differentiating these 2 entities.3 Other concomitant conditions noted in our review included androgenic alopecia, Sjögren syndrome, psoriasis, hypothyroidism, morphea, and HIV, suggesting a potential interplay between autoimmune, genetic, hormonal, and environmental components in the etiology of FFA. In fact, a recent study found that a persistent inflammatory response, loss of immune privilege, and a genetic susceptibility are some of the key processes in the pathogenesis of FFA.18 Although the authors speculated that there may be other triggers in initiating the onset of FFA, such as steroid hormones, sun exposure, and topical allergens, more evidence and controlled studies are needed

Additionally, concomitant LPPigm occurred in 13.7% of our FFA cohort, which appears to be more common in patients with darker skin types.5,19-21 Lichen planus pigmentosus is a rare variant of LPP, and previous reports suggest that it may be associated with FFA.5 Similar to FFA, the pathogenesis of LPPigm also is unclear, and its treatment may be just as difficult.22 Because LPPigm may occur before, during, or after onset of FFA,23 it may be helpful for clinicians to search for the signs of LPPigm in patients with darker skin types patients presenting with hair loss both as a diagnostic clue and so that treatment may be tailored to both conditions.

 

 

Response to Treatment—Similar to the varying clinical pictures, the response to treatment also can vary between patients of different ethnicities. For Black patients, treatment outcomes did not seem as successful as they did for other patients with SOC described in the literature. A retrospective cohort of 58 Asian individuals with FFA found that up to 90% had improvement or stabilization of FFA after treatment,23 while only 45.1% (23/51) of the Black patients included in our study had improvement or stabilization. One reason may be that a greater proportion of Black patients are premenopausal at FFA onset (53%) compared to what is reported in Asian patients (28%),23 and women who are premenopausal at FFA onset often face more severe disease.15 Although there may be additional explanations for these differences in treatment outcomes between ethnic groups, further investigation is needed.

All patients included in our study received either monotherapy or combination therapy of topical/intralesional/oral steroids, HCQ or CHQ, 5-ARIs, topical/oral minoxidil, antifungal shampoo, and/or a calcineurin inhibitor; however, most patients (51.0%) did not see a response to treatment, while only 45.1% showed slowed or halted progression of FFA. Hair regrowth was rare, occurring in only 3 (5.9%) patients; 2 of them were the only patients treated with oral prednisone, making for a potentially promising therapeutic for Black patients that should be further investigated in larger controlled cohort studies. In a prior study, intramuscular steroids (40 mg every 3 weeks) plus topical minoxidil were unsuccessful in slowing the progression of FFA in 3 postmenopausal women,24 which may be explained by the racial differences in the response to FFA treatments and perhaps also menopausal status. Although not included in any of the regimens in our review, isotretinoin was shown to be effective in an ethnically unspecified group of patients (n=16) and also may be efficacious in Black individuals.25 Although FFA may stabilize with time,26 this was not observed in any of the patients included in our study; however, we only included patients who were treated, making it impossible to discern whether resolution was idiopathic or due to treatment.

Future Research—Research on treatments for FFA is lacking, especially in patients with SOC. Although we observed that there may be differences in the treatment response among Black individuals compared to other patients with SOC, additional studies are needed to delineate these racial differences, which can help guide management. More randomized controlled trials evaluating the various treatment regimens also are required to establish treatment guidelines. Frontal fibrosing alopecia likely is underdiagnosed in Black individuals, contributing to the lack of research in this group. Darker skin can obscure some of the clinical and dermoscopic features that are more visible in fair skin. Furthermore, it may be challenging to distinguish clinical features of FFA in the setting of concomitant traction alopecia, which is more common in Black patients.27 Frontal fibrosing alopecia presenting in Black women also is less likely to be biopsied, contributing to the tendency to miss FFA in favor of traction or androgenic alopecia, which often are assumed to be more common in this population.2,27 Therefore, histologic evaluation through biopsy is paramount in securing an accurate diagnosis for Black patients with frontotemporal alopecia.

Study Limitations—The studies included in our review were limited by a lack of control comparison groups, especially among the retrospective cohort studies. Additionally, some of the studies included cases refractory to prior treatment modalities, possibly leading to a selection bias of more severe cases that were not representative of FFA in the general population. Thus, further studies involving larger populations of those with SOC are needed to fully evaluate the clinical utility of the current treatment modalities in this group.

Frontal fibrosing alopecia (FFA) is a lymphocytic cicatricial alopecia that primarily affects postmenopausal women. Considered a subtype of lichen planopilaris (LPP), FFA is histologically identical but presents as symmetric frontotemporal hairline recession rather than the multifocal distribution typical of LPP (Figure 1). Patients also may experience symptoms such as itching, facial papules, and eyebrow loss. As a progressive and scarring alopecia, early management of FFA is necessary to prevent permanent hair loss; however, there still are no clear guidelines regarding the efficacy of different treatment options for FFA due to a lack of randomized controlled studies in the literature. Patients with skin of color (SOC) also may have varying responses to treatment, further complicating the establishment of any treatment algorithm. Furthermore, symptoms, clinical findings, and demographics of FFA have been observed to vary across different ethnicities, especially among Black individuals. We conducted a systematic review of the literature on FFA in Black patients, with an analysis of demographics, clinical findings, concomitant skin conditions, treatments given, and treatment responses.

Methods

A PubMed search of articles indexed for MEDLINE was conducted of studies investigating FFA in patients with SOC from January 1, 2000, through November 30, 2020, using the terms frontal fibrosing alopecia, ethnicity, African, Black, Asian, Indian, Hispanic, and Latino. Articles were included if they were available in English and discussed treatment and clinical outcomes of FFA in Black individuals. The reference lists of included studies also were reviewed. Articles were assessed for quality of evidence using a 4-point scale (1=well-designed randomized controlled trials; 2=controlled trials with limitations or well-designed cohort or case-control studies; 3=case series with or without intervention; 4=case reports). Variables related to study type, patient demographics, treatments, and clinical outcomes were recorded.

Results

Of the 69 search results, 8 studies—2 retrospective cohort studies, 3 case series, and 3 case reports—describing 51 Black individuals with FFA were included in our review (eTable). Of these, 49 (96.1%) were female and 2 (3.9%) were male. Of the 45 females with data available for menopausal status, 24 (53.3%) were premenopausal and 21 (46.7%) were postmenopausal; data were not available for 4 females. Patients identified as African or African American in 27 (52.9%) cases, South African in 19 (37.3%), Black in 3 (5.9%), Indian in 1 (2.0%), and Afro-Caribbean in 1 (2.0%). The average age of FFA onset was 43.8 years in females (raw data available in 24 patients) and 35 years in males (raw data available in 2 patients). A family history of hair loss was reported in 15.7% (8/51) of patients.

Involved areas of hair loss included the frontotemporal hairline (51/51 [100%]), eyebrows (32/51 [62.7%]), limbs (4/51 [7.8%]), occiput (4/51 [7.8%]), facial hair (2/51 [3.9%]), vertex scalp (1/51 [2.0%]), and eyelashes (1/51 [2.0%]). Patchy alopecia suggestive of LPP was reported in 2 (3.9%) patients.

Patients frequently presented with scalp pruritus (26/51 [51.0%]), perifollicular papules or pustules (9/51 [17.6%]), and perifollicular hyperpigmentation (9/51 [17.6%]). Other associated symptoms included perifollicular erythema (6/51 [11.8%]), scalp pain (5/51 [9.8%]), hyperkeratosis or flaking (3/51 [5.9%]), and facial papules (2/51 [3.9%]). Loss of follicular ostia, prominent follicular ostia, and the lonely hair sign (Figure 2) was described in 21 (41.2%), 5 (9.8%), and 15 (29.4%) of patients, respectively. Hairstyles that involve scalp traction (19/51 [37.3%]) and/or chemicals (28/51 [54.9%]), such as hair dye or chemical relaxers, commonly were reported in patients prior to the onset of FFA.

The most commonly reported dermatologic comorbidities included traction alopecia (17/51 [33.3%]), followed by lichen planus pigmentosus (LLPigm)(7/51 [13.7%]), LPP (2/51 [3.9%]), psoriasis (1/51 [2.0%]), and morphea (1/51 [2.0%]). Reported comorbid diseases included Sjögren syndrome (2/51 [3.9%]), hypothyroidism (2/51 [3.9%]), HIV (1/51 [2.0%]), and diabetes mellitus (1/51 [2.0%]).

Of available reports (n=32), the most common histologic findings included perifollicular fibrosis (23/32 [71.9%]), lichenoid lymphocytic inflammation (22/23 [95.7%]) primarily affecting the isthmus and infundibular areas of the follicles, and decreased follicular density (21/23 [91.3%]).

 

 

The average time interval from treatment initiation to treatment assessment in available reports (n=25) was 1.8 years (range, 0.5–2 years). Response to treatment included regrowth of hair in 5.9% (3/51) of patients, FFA stabilization in 39.2% (20/51), FFA progression in 51.0% (26/51), and not reported in 3.9% (2/51). Combination therapy was used in 84.3% (43/51) of patients, while monotherapy was used in 11.8% (6/51), and 3.9% (2/51) did not have any treatment reported. Response to treatment was highly variable among patients, as were the combinations of therapeutic agents used (Table). Regrowth of hair was rare, occurring in only 2 (100%) patients treated with oral prednisone plus hydroxychloroquine (HCQ) or chloroquine (CHQ), and in 1 (50.0%) patient treated with topical corticosteroids plus antifungal shampoo, while there was no response in the other patient treated with this combination.

Treatment Response in Black Patients With FFA (N=51)

Improvement in hair loss, defined as having at least slowed progression of FFA, was observed in 100% (2/2) of patients who had oral steroids as part of their treatment regimen, followed by 5-alpha-reductase inhibitors (5-ARIs)(finasteride and dutasteride; 62.5% [5/8]), intralesional steroids (57.1% [8/14]), HCQ/CHQ (42.9% [15/35]), topical steroids (41.5% [17/41]), antifungal shampoo (40.0% [2/5]), topical/oral minoxidil (36.0% [9/25]), and tacrolimus (33.3% [7/21]).

Comment

Frontal fibrosing alopecia is a progressive scarring alopecia and a clinical variant of LPP. First described in 1994 by Kossard,1 it initially was thought to be a disease of postmenopausal White women. Although still most prevalent in White individuals, there has been a growing number of reports describing FFA in patients with SOC, including Black individuals.10 Despite the increasing number of cases over the years, studies on the treatment of FFA remain sparse. Without expert guidelines, treatments usually are chosen based on clinician preferences. Few observational studies on these treatment modalities and their clinical outcomes exist, and the cohorts largely are composed of White patients.10-12 However, Black individuals may respond differently to these treatments, just as they have been shown to exhibit unique features of FFA.3

Demographics of Patients With FFA—Consistent with our findings, prior studies have found that Black patients are more likely to be younger and premenopausal at FFA onset than their White counterparts.13-15 Among the Black individuals included in our review, the majority were premenopausal (53%) with an average age of FFA onset of 46.7 years. Conversely, only 5% of 60 White females with FFA reported in a retrospective review were premenopausal and had an older mean age of FFA onset of 64 years,1 substantiating prior reports.

Clinical Findings in Patients With FFA—The clinical findings observed in our cohort were consistent with what has previously been described in Black patients, including loss of follicular ostia (41.2%), lonely hair sign (29.4%), perifollicular erythema (11.8%), perifollicular papules (17.6%), and hyperkeratosis or flaking (5.9%). In comparing these findings with a review of 932 patients, 86% of whom were White, the observed frequencies of follicular ostia loss (38.3%) and lonely hair sign (26.7%) were similar; however, perifollicular erythema (44.2%), and hyperkeratosis (44.4%) were more prevalent in this group, while perifollicular papules (6.2%) were less common compared to our Black cohort.16 An explanation for this discrepancy in perifollicular erythema may be the increased skin pigmentation diminishing the appearance of erythema in Black individuals. Our cohort of Black individuals noted the presence of follicular hyperpigmentation (17.6%) and a high prevalence of scalp pruritus (51.0%), which appear to be more common in Black patients.3,17 Although it is unclear why these differences in FFA presentation exist, it may be helpful for clinicians to be aware of these unique features when examining Black patients with suspected FFA.

Concomitant Cutaneous Disorders—A notable proportion of our cohort also had concomitant traction alopecia, which presents with frontotemporal alopecia, similar to FFA, making the diagnosis more challenging; however, the presence of perifollicular hyperpigmentation and facial hyperpigmentation in FFA may aid in differentiating these 2 entities.3 Other concomitant conditions noted in our review included androgenic alopecia, Sjögren syndrome, psoriasis, hypothyroidism, morphea, and HIV, suggesting a potential interplay between autoimmune, genetic, hormonal, and environmental components in the etiology of FFA. In fact, a recent study found that a persistent inflammatory response, loss of immune privilege, and a genetic susceptibility are some of the key processes in the pathogenesis of FFA.18 Although the authors speculated that there may be other triggers in initiating the onset of FFA, such as steroid hormones, sun exposure, and topical allergens, more evidence and controlled studies are needed

Additionally, concomitant LPPigm occurred in 13.7% of our FFA cohort, which appears to be more common in patients with darker skin types.5,19-21 Lichen planus pigmentosus is a rare variant of LPP, and previous reports suggest that it may be associated with FFA.5 Similar to FFA, the pathogenesis of LPPigm also is unclear, and its treatment may be just as difficult.22 Because LPPigm may occur before, during, or after onset of FFA,23 it may be helpful for clinicians to search for the signs of LPPigm in patients with darker skin types patients presenting with hair loss both as a diagnostic clue and so that treatment may be tailored to both conditions.

 

 

Response to Treatment—Similar to the varying clinical pictures, the response to treatment also can vary between patients of different ethnicities. For Black patients, treatment outcomes did not seem as successful as they did for other patients with SOC described in the literature. A retrospective cohort of 58 Asian individuals with FFA found that up to 90% had improvement or stabilization of FFA after treatment,23 while only 45.1% (23/51) of the Black patients included in our study had improvement or stabilization. One reason may be that a greater proportion of Black patients are premenopausal at FFA onset (53%) compared to what is reported in Asian patients (28%),23 and women who are premenopausal at FFA onset often face more severe disease.15 Although there may be additional explanations for these differences in treatment outcomes between ethnic groups, further investigation is needed.

All patients included in our study received either monotherapy or combination therapy of topical/intralesional/oral steroids, HCQ or CHQ, 5-ARIs, topical/oral minoxidil, antifungal shampoo, and/or a calcineurin inhibitor; however, most patients (51.0%) did not see a response to treatment, while only 45.1% showed slowed or halted progression of FFA. Hair regrowth was rare, occurring in only 3 (5.9%) patients; 2 of them were the only patients treated with oral prednisone, making for a potentially promising therapeutic for Black patients that should be further investigated in larger controlled cohort studies. In a prior study, intramuscular steroids (40 mg every 3 weeks) plus topical minoxidil were unsuccessful in slowing the progression of FFA in 3 postmenopausal women,24 which may be explained by the racial differences in the response to FFA treatments and perhaps also menopausal status. Although not included in any of the regimens in our review, isotretinoin was shown to be effective in an ethnically unspecified group of patients (n=16) and also may be efficacious in Black individuals.25 Although FFA may stabilize with time,26 this was not observed in any of the patients included in our study; however, we only included patients who were treated, making it impossible to discern whether resolution was idiopathic or due to treatment.

Future Research—Research on treatments for FFA is lacking, especially in patients with SOC. Although we observed that there may be differences in the treatment response among Black individuals compared to other patients with SOC, additional studies are needed to delineate these racial differences, which can help guide management. More randomized controlled trials evaluating the various treatment regimens also are required to establish treatment guidelines. Frontal fibrosing alopecia likely is underdiagnosed in Black individuals, contributing to the lack of research in this group. Darker skin can obscure some of the clinical and dermoscopic features that are more visible in fair skin. Furthermore, it may be challenging to distinguish clinical features of FFA in the setting of concomitant traction alopecia, which is more common in Black patients.27 Frontal fibrosing alopecia presenting in Black women also is less likely to be biopsied, contributing to the tendency to miss FFA in favor of traction or androgenic alopecia, which often are assumed to be more common in this population.2,27 Therefore, histologic evaluation through biopsy is paramount in securing an accurate diagnosis for Black patients with frontotemporal alopecia.

Study Limitations—The studies included in our review were limited by a lack of control comparison groups, especially among the retrospective cohort studies. Additionally, some of the studies included cases refractory to prior treatment modalities, possibly leading to a selection bias of more severe cases that were not representative of FFA in the general population. Thus, further studies involving larger populations of those with SOC are needed to fully evaluate the clinical utility of the current treatment modalities in this group.

Demographics, Clinical Findings, Concomitant Cutaneous Disorders, and Treatment for FFA in Black Patients (N=51)

Frontal fibrosing alopecia (FFA) is a lymphocytic cicatricial alopecia that primarily affects postmenopausal women. Considered a subtype of lichen planopilaris (LPP), FFA is histologically identical but presents as symmetric frontotemporal hairline recession rather than the multifocal distribution typical of LPP (Figure 1). Patients also may experience symptoms such as itching, facial papules, and eyebrow loss. As a progressive and scarring alopecia, early management of FFA is necessary to prevent permanent hair loss; however, there still are no clear guidelines regarding the efficacy of different treatment options for FFA due to a lack of randomized controlled studies in the literature. Patients with skin of color (SOC) also may have varying responses to treatment, further complicating the establishment of any treatment algorithm. Furthermore, symptoms, clinical findings, and demographics of FFA have been observed to vary across different ethnicities, especially among Black individuals. We conducted a systematic review of the literature on FFA in Black patients, with an analysis of demographics, clinical findings, concomitant skin conditions, treatments given, and treatment responses.

Methods

A PubMed search of articles indexed for MEDLINE was conducted of studies investigating FFA in patients with SOC from January 1, 2000, through November 30, 2020, using the terms frontal fibrosing alopecia, ethnicity, African, Black, Asian, Indian, Hispanic, and Latino. Articles were included if they were available in English and discussed treatment and clinical outcomes of FFA in Black individuals. The reference lists of included studies also were reviewed. Articles were assessed for quality of evidence using a 4-point scale (1=well-designed randomized controlled trials; 2=controlled trials with limitations or well-designed cohort or case-control studies; 3=case series with or without intervention; 4=case reports). Variables related to study type, patient demographics, treatments, and clinical outcomes were recorded.

Results

Of the 69 search results, 8 studies—2 retrospective cohort studies, 3 case series, and 3 case reports—describing 51 Black individuals with FFA were included in our review (eTable). Of these, 49 (96.1%) were female and 2 (3.9%) were male. Of the 45 females with data available for menopausal status, 24 (53.3%) were premenopausal and 21 (46.7%) were postmenopausal; data were not available for 4 females. Patients identified as African or African American in 27 (52.9%) cases, South African in 19 (37.3%), Black in 3 (5.9%), Indian in 1 (2.0%), and Afro-Caribbean in 1 (2.0%). The average age of FFA onset was 43.8 years in females (raw data available in 24 patients) and 35 years in males (raw data available in 2 patients). A family history of hair loss was reported in 15.7% (8/51) of patients.

Involved areas of hair loss included the frontotemporal hairline (51/51 [100%]), eyebrows (32/51 [62.7%]), limbs (4/51 [7.8%]), occiput (4/51 [7.8%]), facial hair (2/51 [3.9%]), vertex scalp (1/51 [2.0%]), and eyelashes (1/51 [2.0%]). Patchy alopecia suggestive of LPP was reported in 2 (3.9%) patients.

Patients frequently presented with scalp pruritus (26/51 [51.0%]), perifollicular papules or pustules (9/51 [17.6%]), and perifollicular hyperpigmentation (9/51 [17.6%]). Other associated symptoms included perifollicular erythema (6/51 [11.8%]), scalp pain (5/51 [9.8%]), hyperkeratosis or flaking (3/51 [5.9%]), and facial papules (2/51 [3.9%]). Loss of follicular ostia, prominent follicular ostia, and the lonely hair sign (Figure 2) was described in 21 (41.2%), 5 (9.8%), and 15 (29.4%) of patients, respectively. Hairstyles that involve scalp traction (19/51 [37.3%]) and/or chemicals (28/51 [54.9%]), such as hair dye or chemical relaxers, commonly were reported in patients prior to the onset of FFA.

The most commonly reported dermatologic comorbidities included traction alopecia (17/51 [33.3%]), followed by lichen planus pigmentosus (LLPigm)(7/51 [13.7%]), LPP (2/51 [3.9%]), psoriasis (1/51 [2.0%]), and morphea (1/51 [2.0%]). Reported comorbid diseases included Sjögren syndrome (2/51 [3.9%]), hypothyroidism (2/51 [3.9%]), HIV (1/51 [2.0%]), and diabetes mellitus (1/51 [2.0%]).

Of available reports (n=32), the most common histologic findings included perifollicular fibrosis (23/32 [71.9%]), lichenoid lymphocytic inflammation (22/23 [95.7%]) primarily affecting the isthmus and infundibular areas of the follicles, and decreased follicular density (21/23 [91.3%]).

 

 

The average time interval from treatment initiation to treatment assessment in available reports (n=25) was 1.8 years (range, 0.5–2 years). Response to treatment included regrowth of hair in 5.9% (3/51) of patients, FFA stabilization in 39.2% (20/51), FFA progression in 51.0% (26/51), and not reported in 3.9% (2/51). Combination therapy was used in 84.3% (43/51) of patients, while monotherapy was used in 11.8% (6/51), and 3.9% (2/51) did not have any treatment reported. Response to treatment was highly variable among patients, as were the combinations of therapeutic agents used (Table). Regrowth of hair was rare, occurring in only 2 (100%) patients treated with oral prednisone plus hydroxychloroquine (HCQ) or chloroquine (CHQ), and in 1 (50.0%) patient treated with topical corticosteroids plus antifungal shampoo, while there was no response in the other patient treated with this combination.

Practice Points

  • Treatment of frontal fibrosing alopecia (FFA) is challenging, and there are no evidence-based treatment guidelines available. Patients with skin of color (SOC) may have varying responses to treatment modalities.
  • Special consideration should be taken when treating FFA in patients with SOC.
  • Histologic evaluation through biopsy is paramount in securing an accurate diagnosis for Black patients with frontotemporal alopecia.
