Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hairgrowth.
The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hairgrowth by affecting certain cellular signaling pathways and has anti-androgenic effects.
PP405 and ABS-201 are promising treatments for male pattern baldness. PP405 shows rapid hairgrowth in human trials, while ABS-201 shows significant regrowth in animal studies but is still in early human trials.
Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle 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.
PP405 is a potential hair loss treatment that may activate dormant hair follicles, but there are concerns about its effectiveness, cost, and side effects. Users discuss treatments like minoxidil, finasteride, and RU58841, expressing skepticism about PP405's long-term success and accessibility.
