Mechanism of Action
Copper Delivery
The His residue chelates Cu²⁺ ions and facilitates their controlled delivery to follicle cells and dermal fibroblasts. Copper is essential for lysyl oxidase activity, which cross-links collagen and elastin, and for tyrosinase function in melanin production.Hair Follicle Stimulation
AHK-Cu promotes proliferation of dermal papilla cells and hair follicle stem cells. Research suggests it extends the anagen (growth) phase of the hair cycle and reduces premature entry into catagen (regression).DHT Modulation
Preliminary data indicates AHK-Cu may reduce DHT sensitivity at the follicle level by downregulating androgen receptor expression in dermal papilla cells, though this mechanism is less established than finasteride.Research Summary
Hair Growth
In vitro and ex vivo studies show AHK-Cu increases expression of vascular endothelial growth factor (VEGF) and keratinocyte growth factor (KGF) in follicle tissue, both important for follicle health and cycling.Comparison to GHK-Cu
AHK-Cu is considered more specific to hair follicle activity than GHK-Cu, though GHK-Cu has broader skin repair research support. Both are used together in some protocols.Calculate your AHK-Cu dose Vial strength, BAC water, exact syringe draw in IU. Free, no signup. Open Calc →
Research Protocols
Hair Serum
Typically formulated at 2–5% in an aqueous base and applied directly to the scalp. Massage in gently after washing. Allow 4–6 hours minimum contact before washing.Skin Use
Lower concentrations (0.5–2%) used for periorbital wrinkles and skin texture. Apply after cleansing, before heavier moisturizers.Cycle
Minimum 8 weeks for hair growth endpoints; 16 weeks for full assessment. Some researchers use continuously.Storage & Handling
Store at 2–8°C. Protect from light, copper peptides can oxidize and lose activity when exposed to UV. Use within 60 days of opening. Do not freeze formulated solutions.
