"Hair Follicle Stem Cells are quiescent 99% of the time and permanently reside in the hair follicle" Research/Science 8/27/2025
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.
