PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.
PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
PP405 and hair cloning are discussed as potential treatments for reversing hair loss from Norwood 7 to Norwood 1. Hair cloning is seen as a more permanent solution, while PP405's effectiveness and long-term effects remain uncertain.
