Researchers developed a new method to test hair growth drugs and found that adult cells are best for hair growth, but the method needs improvement as it didn't create mature hairfollicles.
He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hairfollicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.
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.
Hair loss treatments like finasteride, minoxidil, and hair transplants have side effects and limitations. There is hope for future advancements in stem cell therapy and hairfollicle regeneration, though skepticism about their effectiveness and timeline persists.
New potential hair loss treatment uses molecules from hairy moles to stimulate follicle growth. Topical solution requires less frequent application, like Botox injections a few times per year.
Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hairfollicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.
