October 2021 in “Microorganisms” The study analyzed the scalp microbiome and sebum composition of 118 Japanese males, comparing those with androgenetic alopecia (AGA) to those without. It found that individuals with AGA had higher levels of sebum triglycerides and palmitic acid, and their fungal microbiome was dominated by Malassezia restricta. The bacterial microbiome in AGA patients showed increased Cutibacterium and decreased Corynebacterium, indicating scalp dysbiosis. These findings suggest that both sebum composition and microbial imbalances may play roles in the development of AGA.
