AHK-Cu

Alanyl-Histidyl-Lysine Copper Complex

Hair-specific copper peptide with follicle-regenerating activity

Research Status: Preclinical + limited human trials in cosmetic applications AHK Copper Hair copper peptide
Mechanism of Action

How it works

AHK-Cu upregulates FGF-7 (fibroblast growth factor-7, also known as KGF) specifically in hair follicles, stimulating follicle cell proliferation and prolonging the anagen (growth) phase. It also suppresses the androgen pathway implicated in androgenic alopecia.

Areas of Research

What the research explores

In published research, AHK-Cu has been studied in connection with the following. These describe findings reported in the literature — not approved uses, claims, or outcomes to expect.

  • Stimulates hair follicle growth and density
  • Prolongs the anagen (active growth) phase
  • Reduces miniaturization of follicles in androgenic alopecia
  • Complements GHK-Cu for comprehensive hair restoration
  • Promotes scalp tissue health and circulation
  • Anti-inflammatory at follicle level
Research Highlight

AHK-Cu demonstrates 6x greater hair follicle stimulation than Minoxidil in comparative in vitro studies, with synergistic effects when combined with GHK-Cu.
