PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.
Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.
PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.
PP405 shows promise in hair loss treatment, but stem cell therapy using adipose-derived stem cells and ATP also successfully reversed androgenetic alopecia in mice. Stem cell therapy is costly, and some doubt the effectiveness of PP405 based on press releases.
Pelage is delaying the start of phase 3 trials for PP405 to 2026 due to necessary regulatory processes, despite having $120 million in funding. Users discuss the potential of PP405 for hair regrowth, with some expressing skepticism and others hopeful for new treatments like Breezula.
