PP405 shows promise in stimulating new terminal hair growth by activating dormant follicles, with no systemic adverse effects observed in a short-term trial. However, long-term efficacy remains unproven, and further trials are needed to confirm its potential as a hair loss treatment.
community 4 months of progress, lots of new terminal hairs, diffuse thinning. 31m
A 31-year-old man shares his 4-month hair regrowth progress using topical minoxidil, topical finasteride, microneedling, biotin, and other supplements. He reports new hair growth despite experiencing side effects from finasteride and plans to continue his regimen for further improvement.
community A Short Recap on PP405 and AAD 2026
PP405 is a promising experimental topical treatment for alopecia that reactivates dormant hair follicles by targeting cellular energy, with large-scale trials planned for 2026. While it shows potential, it cannot regenerate permanently destroyed follicles, making hair transplants the only guaranteed solution for advanced baldness currently.
community Do you guys have very thin hairs that don’t grow where you lost hair?
Thin, short hairs often appear in areas of hair loss but may not grow fully despite treatments like finasteride. Some users consider additional treatments like microneedling or hair transplants.
