TLDR Androgenetic alopecia is common in South-West Nigeria, affecting more men than women, with stress worsening the condition.

The study on androgenetic alopecia (AGA) in a South-West Nigerian population found a prevalence of 29.95% among 868 community members, with a higher occurrence in males (83.10%) compared to females (16.90%). The study involved 260 participants with AGA and 260 controls. Male androgenetic alopecia (MAGA) had a prevalence of 24.88%, while female androgenetic alopecia (FAGA) was 5.06%. A significant family history of AGA was noted, particularly among male relatives, and stress was identified as a factor worsening alopecia. The mixed pattern of MAGA was most common, with Type IIv being the most frequent severity. The study highlighted the need for more community-based research to understand AGA's epidemiology and clinical characteristics in different regions. There was no financial support or conflicts of interest reported.
