Neurogenic Skin Inflammation in Stress-Triggered Inhibition of Hair Growth in Mice Is Promoted via Nerve Growth Factor-Dependent Pathways

The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

Pelage is recruiting for phase 2 trials, showing promise for treating bald regions. The discussion highlights its potential effectiveness based on its mechanism of action.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.
