AHK-Cu (Alanine-Histidine-Lysine-Copper) is a copper-binding tripeptide that has gained attention for its hair growth-stimulating properties. While related to the well-known GHK-Cu peptide, AHK-Cu has been specifically studied for its effects on hair follicle biology. Research has shown that AHK-Cu can stimulate the proliferation of dermal papilla cells — the key signaling cells at the base of hair follicles that control hair growth cycling.
Key Data
Mechanism of Action
AHK-Cu binds copper(II) ions and delivers them to hair follicles and skin cells, stimulating VEGF production, enhancing dermal papilla cell proliferation, and promoting extracellular matrix remodeling. It activates signaling pathways involved in hair follicle cycling.
