PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
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.
