Evidence at a glance

What the research says about AHK-Cu

The AHK-Cu evidence base cited here is 2 sources — 1 preclinical, 1 review. Critically, that evidence is almost entirely preclinical (animal and in-vitro) — no human clinical trials are cited, so efficacy and safety in people remain unproven.

Key findings

What the literature shows

AHK-Cu is a copper complex of the tripeptide Ala-His-Lys.
One study reported that AHK-Cu stimulated elongation of ex vivo human hair follicles and proliferation of cultured human dermal papilla cells.
This evidence is ex vivo and in vitro. It does not establish a clinical hair-growth benefit in people.
