PP405 is a promising new treatment for hair loss that activates dormant stem cells in hair follicles, potentially bypassing the effects of DHT. It is currently in phase 2 trials and could be available between 2027 and 2030, but it is not considered a definitive cure.
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.
community PP405: The Ultimate Hair Loss Drug for Complete Hair Growth
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
community How true is the statement: dead follicles don't grow back?
Hair follicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.
