Anyone here have a lot of knowledge on hair follicle stem cells and progenitor cells for PP405? Chat 1/2/2026
Hair follicle 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.

5 / 5 resultscommunity PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells
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.
community Reminder: NURTURE those dormant hair follicles for as long as you can until PP405 comes out in 2028-2030
PP405 is anticipated as a future treatment for dormant hair follicles, but its effectiveness and safety are uncertain. Current treatments include oral minoxidil and microneedling, with some avoiding finasteride due to side effects.
community Will PP405 need to be used indefinitely, like minoxidil?
PP405 may not need daily use like minoxidil, but finasteride might still be needed to maintain hair regrowth. PP405 reawakens dormant hair follicles, potentially offering a long-term solution, though not a permanent cure.
community Is PP405 gonna flop or what???
PP405 is viewed skeptically, with some seeing it as overhyped and potentially ineffective compared to existing treatments like minoxidil and finasteride. While it shows some promise in activating dormant hair follicles, many believe it won't replace hair transplants or significantly outperform current options.
community Confused why people are calling PP405 a cure...it never claimed to be able to undo miniaturization or revert vellus back to terminal hairs. It seems to be more of a growth stimulant like minoxidil.
PP405 is not a cure for hair loss but may reactivate dormant hair follicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.
