Did some new info come out about PP405? Everyone seems so pessimistic about it recently and I don’t know why.

Research/Science 8/11/2026

PP405 is a potential hair loss treatment that may activate dormant hair follicles, but there are concerns about its effectiveness, cost, and side effects. Users discuss treatments like minoxidil, finasteride, and RU58841, expressing skepticism about PP405's long-term success and accessibility.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

Dutasteride and finasteride are not effective for everyone in treating hair loss, with some users experiencing worsening conditions. Many are hopeful for new treatments like PP405, while others consider hair transplants or alternative medications.

UCLA's PP405 shows promise in reactivating dormant hair follicles for hair loss treatment but is still in clinical trials. Minoxidil and finasteride remain common treatments until PP405 becomes available.

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.
