learn GHK-Cu

a copper peptide showing promise in both regrowth and reversing gray hair

What is GHK-Cu and why is it said to be a "miracle" for hair? GHK-Cu is a copper peptide studied mainly for wound healing and skin repair; for hair loss the evidence stops at cell-culture and animal work, and no published human trial has tested it for androgenetic alopecia.
GHK-Cu: Is it better than minoxidil or finasteride, or just a complement? There is no completed human trial of GHK-Cu for androgenetic alopecia, so it cannot be compared with minoxidil or finasteride on evidence; clinics and community users treat it as an unproven add-on, not a replacement.
GHK-Cu: What is the most recommended product? No GHK-Cu product has published human trial evidence for hair loss, so none can be ranked on efficacy; what separates products is formulation quality — purity, stability and third-party testing — and the FDA lists GHK-Cu among bulk substances that may present significant safety risks in compounding.
