Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.
Collagen, chondroitin sulfate, hyaluronic acid, and MSM are used to improve hair appearance, making it fuller, thicker, and shinier. The user noticed significant hair improvement after resuming these supplements.
The conversation discusses interest in peptides for hair loss, specifically mentioning ahkCU and ghkCU. A user is considering adding ghkCU to their treatment regimen.
A peptide-based hair loss treatment, PP405, reportedly increased hair density by 62% in 90 days, but these claims are unverified and met with skepticism. Users compared PP405 to Minoxidil and Finasteride, expressing doubts about its effectiveness without more evidence.
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.
