Pohl-Pinkus Constrictions of Hair Following Chemotherapy for Hodgkin's Disease

PP405 trials have completed phase 2a, showing promising results with a 31% stat for hair density increase, and are moving directly to phase 3. Detailed results will be presented at a medical conference in 2026.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.

People are discussing the anticipated release of PP405 phase 2a results, expected by the end of March, with some skepticism about its effectiveness. There is cautious optimism due to past experiences with similar treatments like Breezula, despite concerns about the lack of presentation at the AAD 2026 conference.

New hair loss treatments PP405 and VDPHL01 are discussed with skepticism and hope, alongside existing treatments like minoxidil and finasteride. Users express frustration over limited progress since the 1980s but remain cautiously optimistic.

PTD-DBM therapy for hair loss is being developed by Dr. Kang-Yell Choi, with human testing planned in South Korea. Some clinics in the U.S. offer PTD-DBM/valproic acid therapy, but it hasn't completed trials yet.
