Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
KPV, a peptide patented by L'Oreal, may promote hair growth and reduce hair loss by extending the anagen phase and has anti-inflammatory properties. It could be combined with treatments like minoxidil for enhanced effects.
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.
Iontophoresis and sonophoresis can enhance drug delivery into the scalp. Combining these methods may improve the effectiveness of topical treatments like dutasteride and certain peptides.
Dutasteride has been used for 20 years with some hair thickness improvement but no dramatic regrowth. The user also experimented with minoxidil, tretinoin, and peptides like BPC 157 for potential benefits in hair density and quality.
