The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.
Hairfollicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.
PP405 is ineffective for miniaturized, fibrosed hairfollicles in androgenetic alopecia. AMP303 may activate hairfollicle stem cells, but minoxidil and finasteride are still the main treatments.
Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
