L-Ascorbic Acid 2-Phosphate Promotes Elongation of Hair Shafts via the Secretion of Insulin-Like Growth Factor-1 from Dermal Papilla Cells Through Phosphatidylinositol 3-Kinase

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.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Increasing IGF-1 may help hair growth, but it could also increase hair loss in people with high testosterone. Treatments discussed include l-arginine, glutamine, vanadium, Deer Antler Velvet, ATP, Cocarboxylase, l-carnitine, and Mk677.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

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.
