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: 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.
GHK-Cu: Does it have side effects or is it completely safe? For topical cosmetic use, the small laboratory evidence base found GHK-Cu non-irritating, and reported reactions are local and uncommon; for injected or oral use there is effectively no human safety data, and the FDA lists GHK-Cu among bulk substances that may present significant safety risks in compounding.
