Non-Scarring Alopecia in Black Women: Diagnosis, Impact, and Emerging Evidence

Conclusions

• Non-scarring alopecia in Black women has a major quality-of-life impact, with especially high mental, social, and activity burden and frequent dissatisfaction with current treatments.
• Scalp biopsy is underused but often changes the diagnosis in Black women with alopecia, suggesting that clinical overcalling of traction alopecia and multifactorial hair loss is common.
• Frontal hairline and vertex hair loss in Black women can be diagnostically misleading, so clinicians should have a low threshold to biopsy when the pattern is uncertain.
• Alopecia areata is a complex autoimmune disease with common associations to atopy, thyroid disease, psychiatric disease, and possibly other systemic comorbidities.
• The apparent link between alopecia areata and race is inconsistent across studies, and some evidence suggests hair color or other confounders may explain part of the association.
• Current alopecia areata trials and emerging treatments still lack adequate racial diversity, limiting how confidently results can be applied to Black patients.
• Female pattern hair loss in Black women may more often show vertex scalp involvement, indicating that its presentation may differ from that seen in other groups.
• Telogen effluvium in Black women can be missed or misread because protective styles such as locs or braids change how shedding appears.
• The hair pull test remains useful across hair textures, but clinicians must distinguish true telogen hairs from broken hairs to avoid misdiagnosis.
• Medication-related hair loss, including from GLP-1 agonists, is usually uncommon and often occurs on a background of pre-existing alopecia rather than as a wholly new problem.
• Acquired trichorrhexis nodosa and other breakage disorders improve most with moisturizing, reduced tension, and better hair-care practices rather than alopecia medications.
• Scalp cooling for chemotherapy-induced alopecia may be less effective or less tolerable in Black women with certain hair types and styling practices, so treatment strategies need better tailoring.
• Hair texture changes such as the downy hair sign can be an important clue to non-scarring alopecia from connective tissue disease, including acute lupus alopecia.
