Preclinical research shows GHK-Cu increases hair follicle size, in part by acting on dermal papilla cells (the signaling cells at the base of the follicle that control hair growth cycles), and can push follicles out of the resting (telogen) phase and back into active growth (anagen). Human data here is thinner than the skin research, mostly early-phase and follicle-culture studies rather than large trials, so this should be understood as a promising, evidence-informed application rather than a proven hair-loss treatment on the level of prescription options
