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.
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.
PP405 is not a cure for hair loss but may reactivate dormant hairfollicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.
