Hairfollicles 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.
Corticosterone inhibits GAS6, affecting hairfollicle 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.
PP405 may damage hairfollicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hairfollicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
