Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.
PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.
Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.
Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.
