AHK-Cu
A copper-bound tripeptide studied for its role in hair follicle stimulation and dermal health. AHK-Cu is researched alongside GHK-Cu for its effects on hair growth, vascularization, and collagen support.
The copper peptide for hair.
AHK-Cu (alanyl-L-histidyl-L-lysine, copper-bound) is a copper-binding tripeptide from the same family as the more familiar GHK-Cu, but with a research profile that has centered on a different question: hair. Where GHK-Cu became the reference point for skin and collagen research, AHK-Cu has drawn attention for its studied effects on the hair follicle and the vascular support that surrounds it.
Hair changes are one of the quieter frustrations of aging, and one women feel acutely. Thinning, slower growth, and a loss of density often begin long before they’re obvious to anyone else—and they trace back, in part, to the same declines in follicular circulation and dermal support that AHK-Cu research addresses.
Published research has documented AHK-Cu’s role in promoting hair follicle growth and prolonging the anagen (active growth) phase, stimulating vascular endothelial growth factor (VEGF) to support the microcirculation feeding the follicle, and supporting collagen synthesis as a copper-delivery peptide. It sits among the most-discussed peptides in the hair and dermal research literature.
