Proof DHT is not the main cause of hair loss. TRPS1 Gene and Protein might be. PP405 won’t work. AMP-303 might! Research/Science 3/10/2026
Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

6 / 1000+ resultscommunity Thinking about using PP405 and RU58841
The conversation is about a person using dutasteride and minoxidil for hair loss, considering adding RU58841 and PP405 for more density. They are seeking advice on using these treatments and exploring other options like GT20029.
community If PP405 does revive "dead" hair follicles would DHT blockers theoretically be enough to maintain that new hair
PP405 may revive dormant hair follicles, and DHT blockers like finasteride or dutasteride could maintain new hair. Combining PP405 with minoxidil might be optimal, but long-term effects and continuous use are uncertain.
community Is pp405 actually the cure ? Just how exciting is it ?
PP405 is a promising hair growth stimulant but not a cure for advanced hair loss, as it may only help dormant follicles. Treatments like Minoxidil, Finasteride, and Dutasteride are discussed, with emphasis on early intervention for effectiveness.
community When should we get the next news about PP405
Results for PP405 are expected next year, with concerns about its pricing and potential black market availability. Some users believe it may be slightly more effective than finasteride and dutasteride, and combining it with treatments like minoxidil and microneedling could be beneficial.
community October 2025 $120M funding round for PP405 — hype justified or too early to celebrate?
Pelage secured $120 million for PP405, a non-hormonal topical hair loss treatment, sparking debate on its potential as a breakthrough. Concerns about finasteride's side effects persist, with some suggesting alternatives like topical finasteride or dutasteride.
community Why does Pelage PP405 receive so much attention, while Eirion ET-02 seems to be almost forgotten?
ET-02 is seen as promising for addressing hair loss and graying, but PP405 is more advanced in development and has better publicity. Some users plan to use both treatments alongside minoxidil and dutasteride.
