VDPHL01 - could it be the replacement to DHT blockers?

Research/Science 3/25/2026

PP405 is considered a promising hair loss treatment, potentially replacing minoxidil but not finasteride. Users are hopeful for future treatments like GT20029 and VDPHL01, while remaining cautious about effectiveness and side effects.

The conversation discusses skepticism and diminishing excitement around the hair loss treatment PP405 due to unclear trial results. It also mentions other treatments like finasteride, minoxidil, VDPHL01 (extended-release minoxidil), and GT20026 as potential options for hair loss management.

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.

PP405 shows promise in activating dormant hair follicles and increasing hair counts but lacks detailed efficacy data compared to minoxidil and finasteride. Opinions are mixed, with some optimism and skepticism about its effectiveness.

Hair regrowth was achieved using minoxidil, nizoral, alfatrodial, and pyrilutamide after finasteride caused side effects. The user recommends this combination for those who can't tolerate 5AR inhibitors, stressing consistent use.
