GHK-Cu
Copper Peptides
Small protein fragments bound to copper ions, studied for wound healing and tissue remodeling.
Copper peptides, particularly GHK-Cu (glycyl-L-histidyl-L-lysine-copper), are naturally occurring complexes that decrease with age. They play roles in wound healing, collagen synthesis, glycosaminoglycan production, and tissue remodeling. In hair research, copper peptides are studied for their potential to increase hair follicle size, stimulate hair growth phase (anagen), and improve scalp health. They are primarily applied topically as serums or shampoo additives. GHK-Cu was first identified in human plasma in 1973 and has since been the subject of over 60 studies on tissue repair mechanisms.
