AHK-Cu
What is AHK-Cu ?
AHK-Cu is a short copper-binding tripeptide (alanine-histidine-lysine) developed with a focus on hair-follicle biology. In controlled laboratory models using isolated human hair follicles, AHK-Cu lengthened hair-shaft growth and supported dermal papilla, the key cells at the base of the follicle, helping maintain the active growth phase (anagen).REF 1
Like other copper peptides, it helps rebalance local signalling, encouraging pro-growth cues while tempering the "slow-down" messages that push follicles toward rest (telogen), creating conditions that favour continued growth.REF 2
Topically, copper tripeptides can penetrate and persist in skin, making AHK-Cu well suited to leave-on scalp formulas and to pairing with treatments such as minoxidil.REF 3
Like its close cousin GHK-Cu, AHK-Cu delivers copper in a bioavailable, skin-friendly form while contributing antioxidant and calming effects - supporting follicle function, scalp comfort, and fuller-looking hair over time.REF 4
Key benefits:
- Supports a longer growth phase (anagen) by promoting dermal papilla cell activity and survival.
- Encourages a pro-growth micro-environment, tipping signals toward active growth and away from inhibitory cues.
- Helps calm micro-inflammation that can contribute to follicle miniaturisation and scalp sensitivity.
- Supports microcirculation around follicles, aiding nutrient delivery where it's needed most.
