community People are misunderstanding PP405. 31% response at 8 weeks is better than you think
PP405 shows promise as a hair loss treatment, with 31% experiencing increased hair density in a short trial. It may complement treatments like finasteride and minoxidil, but long-term effectiveness and safety need confirmation.
community PP405 Phase 2a press release with early results
PP405 shows promise in hair regrowth, with 31% of participants experiencing over 20% increase in hair density after 8 weeks. Phase 3 trials are expected in 2026, with potential market availability by 2029-2031.
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.
