Proposed mechanisms / pathways
What is Ahk-Cu?
AHK-Cu is a copper-binding tripeptide (alanyl-L-histidyl-L-lysine bound to a copper ion). It is a close cousin of the more widely studied GHK-Cu, and in cosmetic science it is most often discussed in the context of hair and scalp research. It appears mainly in topical formulations and serums rather than as a clinical drug.
How it is thought to work
Like other copper peptides, AHK-Cu’s headline idea is delivering copper, a cofactor your body uses in collagen and elastin production and in various skin and follicle processes. It is also discussed in relation to signaling around the hair follicle and support for the skin’s structural matrix. These are proposed mechanisms drawn largely from cosmetic and preliminary research, not guaranteed outcomes.
Educational only — not medical advice
AHK-Cu is used cosmetically and in research; this page is not a recommendation, dose, or medical claim. Patch-test topicals and consult a qualified professional before use, and follow the laws in your area.
Tracking Ahk-Cu in LynkDose
Hair and scalp changes are slow and easy to misjudge from memory, which makes AHK-Cu a strong candidate for photo-based tracking in LynkDose. Log each application, attach consistent progress photos at regular intervals, and let the visual timeline do the work — side-by-side photos months apart tell you far more than a daily glance in the mirror.
Commonly discussed for
- Hair and scalp research
- Skin appearance and tone

How to track Ahk-Cu in LynkDose
Hair and scalp changes are slow, so pair your log with consistent, well-lit photos at fixed intervals. Recording dose and dated pictures makes gradual changes far easier to judge than memory.
