Аннотация
BACKGROUND: Frontal fibrosing alopecia (FFA) is a primary lymphocytic scarring alopecia characterized by progressive recession of the frontotemporal hairline, affecting mainly postmenopausal and, lately, premenopausal women of African descent. Considering the importance of trichoscopy on FFA diagnosis and the peculiarities found in patients with higher skin phototypes, this study aimed to review the FFA trichoscopy in the black scalp (Fitzpatrick IV-VI), a topic that remains sparsely described in the existing literature.
SUMMARY: In black patients, FFA may manifest singular features on presentation posing diagnostic clinical and trichoscopic challenges. This group has lower prevalence of the FFA compared to other alopecias. It may have an earlier age of onset and often exhibits more severe manifestations due to the coexistence of other types of alopecia and delay in diagnosis. The early signs of the disease in black patients may manifest in the eyebrows before scalp hair loss and lichen planus pigmentosus may be a herald sign.
KEY MESSAGES: Our research analyzes FFA trichoscopy findings in black patients to help precise diagnosis and treatment. Raising awareness of the disease characteristics on trichoscopy contributes to improving hair care in this population.
