Marginal Traction Alopecia: Hair Care Practices, Severity Score and Trichoscopic Features in Lagos, Nigeria

Marginal traction alopecia (MTA) is commonly observed in adult females. Studies of prevalence, severity, trichoscopy and severity scoring are few.

The aim of this study was to determine the community prevalence, pattern, severity score and trichoscopy features of MTA amongst adult Nigerian females. Patient and method: This was a cross-sectional descriptive study of a cohort of 207 adult females in a community in Lagos, Nigeria. The participants were clinically evaluated for MTA. Sociodemographic, clinical and trichoscopy data was documented. Severity score was documented using the MTA severity score. Data was analyzed using SPSS version 22.

The mean age of participants was 43±12.8 years and the prevalence of MTA was 76.3%. Marginal traction alopecia was frontoccipital in 65.2%. The MTA score was 1-3 in 22.2%, 4-6 in 29.7% and ≥6 in 48.1%. Fringe sign was observed in 30.4%, folliculitis in 9.5% and 13.9% had tight weaves. Trichoscopic features included preserved honeycomb pigment, preserved white dot architecture, varying hair length and single hairs from hair follicles.

Marginal traction alopecia is common in Nigerian women. It is mostly severe, severity is not significantly associated with haircare practices and it is represented by common trichoscopy features. Appropriate awareness and education of females on hair styles can mitigate this hair loss.
