BACKGROUND: Hair loss studies have mostly been clinical with no trichoscopy features of the hair loss documented in Nigeria.
OBJECTIVE: The objective of this study was to determine the community prevalence, types of hair loss, trichoschopy features and the risk factors for the observed hair loss types.
METHODS: This was a cross-sectional descriptive study of traders (Fitz Patrick's skin types V-VI) at an urban market. The traders were clinically evaluated for hair loss. Sociodemographic, clinical and trichoscopy data were recorded using a study questionnaire. Data was analyzed using SPSS version 22.0. Statistics such as means, medians, frequencies, t-test and chi-square test were presented. Levels of significance of all tests was set at, P<0.05%.
RESULTS: A total of 307 participants (32.6% male and 67.4% female) with a mean age of 42.7±12.8 years were studied. The prevalence of hair loss was 68.7% (51% in males and 77.3% in females) and the mean age of those with hair loss was 44.8±12.3 years. The pattern of hair loss was patterned, diffuse and localized in 94.3%, 3.8% and 1.9% respectively. The main types of hair loss were androgenetic alopecia (26.9%) and traction alopecia (71.7%). The prevalent hair practices were; braids and weave-on (extensions) in 78.2%, turban-like head gear in 76.9%, and chemical relaxers in 73.8%. Trichoscopy features characteristic of the observed hair loss types were documented.
CONCLUSION: Hair loss is common in the community. The common hair care practices and increasing age could be contributors to hair loss.
