The Natural History of Androgenetic Alopecia

This study looks at the natural history of androgenetic alopecia (AGA), a common condition which affects up to 80% of men and 50% of women in their lifetime. It reviews recent data about natural progression of the disease, as well as factors that may interfere with its course and long-term prognosis. The paper suggests that miniaturization of hair follicles, which causes AGA, can occur either slowly or rapidly and that potential accelerating factors include androgen metabolism, inflammatory scalp disorders, lifestyle choices, and scalp microorganisms. The study also shows correlations between AGA and life-threatening conditions such as coronary artery disease and prostate cancer, and discusses treatments for AGA, suggesting that early treatment is important for best results.
