PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

A user's 11-month hair loss treatment progress using 0.5mg dutasteride every other day, 50mg RU58841 in the morning, 5mg oral minoxidil, topical minoxidil at night, and microneedling with a 1.5mm needle every other week. The user's improvement was significant, going from a severe hair loss stage (NW7) to a mild/moderate stage (NW2-3).

PP405, a promising hair loss treatment, is expected to be available by 2027, with faster trials due to its topical nature. Users are eager for its release, comparing it to existing treatments like minoxidil and finasteride, but remain cautious about its long-term effectiveness.
