GHK-Cu and Hair Research: Mechanisms, Evidence and UK Studies (2026) GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) has attracted substantial research interest in hair biology over the past two decades, following the discovery that it stimulates dermal papilla cell proliferation, promotes follicle enlargement, and modulates several growth factors directly relevant to the hair growth cycle

GHK-Cu activates the Wnt/beta-catenin pathway that drives the anagen (growth) phase of the hair cycle, stimulates VEGF and hepatocyte growth factor for follicle health, and has been shown in clinical research to increase follicle size and density with sustained use
