Neurotrophology of the Hair Follicle: Neurotrophins Act as Auto- and Paracrine Growth Factors and Immunomodulators

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.

The conversation discusses hair loss linked to BDNF-increasing nootropics like Semax and Lions Mane. Suggested topical treatments include capsaicin, beta-glucan, and ginseng to counteract TGF-B activation.

PP405, developed by Pelage Pharmaceuticals, can reactivate dormant hair follicle stem cells and increase hair growth by 20% in eight weeks, unlike minoxidil or finasteride. However, skepticism remains about its effectiveness and availability, with concerns about funding and the timeline for broader access.

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

The conversation discusses using GFM Gel, a topical gel with polypeptides that mimic growth factors to promote hair regrowth and strengthen hair. It also mentions treatments like Minoxidil, finasteride, and RU58841 for hair loss.

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.
