AHK-Cu (Copper Tripeptide-3)

AHK-Cu is a synthetic copper-binding tripeptide with in vitro and ex vivo evidence for stimulating hair follicle elongation, dermal papilla cell proliferation, and VEGF production. Limited clinical data exists; most evidence is from cell-based studies or animal models. Topical application shows good skin penetration but long-term human safety data is minimal.
