AHK-Cu
Copper Peptide for Hair & Scalp Research
AHK-Cu (Alanine-Histidine-Lysine + Copper) is a copper-binding tripeptide closely related to GHK-Cu but with a distinct amino acid sequence that has shown particular affinity for scalp and hair follicle tissue. Studied primarily for its ability to activate hair follicle stem cells, extend the anagen phase, and modulate DHT-related signaling at the follicle level.
At a Glance
Like GHK-Cu, AHK-Cu delivers bioavailable copper to tissue — but its tissue tropism appears more targeted to the dermal papilla, the cluster of cells at the base of each hair follicle that governs follicle cycling, growth, and miniaturization.
Research interest in AHK-Cu has grown as an adjunct or alternative to minoxidil and finasteride in hair loss models — compounds whose side effect profiles have driven demand for mechanism-specific alternatives in research settings.
Its combination with GHK-Cu in haircare research is natural — the two copper peptides cover complementary tissue targets and are frequently studied together in scalp inflammation and follicle repair protocols.
This compound operates through several converging biological pathways, which helps explain the breadth of effects observed across different tissue and metabolic models.
Dermal Papilla Activation
Stimulates dermal papilla cell proliferation and Wnt/β-catenin signaling — key regulators of the anagen growth phase initiation.
Copper Delivery to Follicle
Delivers bioavailable Cu²⁺ to follicle tissue, supporting copper-dependent enzymes involved in keratin crosslinking and extracellular matrix remodeling.
Anti-Inflammatory (Scalp)
Reduces scalp inflammation that contributes to follicle miniaturization — addresses the inflammatory component of androgenic alopecia.
Anagen Extension
Studied for extension of the hair growth phase (anagen) and delay of catagen (regression) in follicle cycling models.
Preclinical and clinical models have investigated this compound across a wide range of physiological contexts and tissue types.
- Hair follicle activation and anagen phase extension in preclinical models
- Androgenic alopecia (pattern hair loss) — DHT signaling modulation at follicle level
- Scalp inflammation — anti-inflammatory mechanism as contributor to hair loss research
- Dermal papilla cell proliferation — Wnt/β-catenin pathway activation
- Comparison models vs minoxidil — mechanism-specific hair growth alternative
- Combination research with GHK-Cu for comprehensive scalp and follicle protocols
- Topical delivery systems — penetration enhancer research for scalp application
AHK-Cu's follicle-specific mechanism makes it a precise tool for hair biology research — more targeted than vasodilatory or hormonal approaches.
AHK-Cu and GHK-Cu are complementary copper peptides for scalp and skin research — with AHK-Cu more follicle-specific and GHK-Cu broader in skin biology.
| Aspect | AHK-Cu | GHK-Cu | Minoxidil (reference) |
|---|---|---|---|
| Primary Mechanism | Dermal papilla activation, Wnt/β-catenin | Collagen synthesis, gene expression | Vasodilation, KATP channel opening |
| Tissue Focus | Hair follicle, scalp | Skin, wound, collagen | Scalp vasculature |
| Route | Topical or injectable | Topical or injectable | Topical or oral |
| DHT Interaction | Indirect (papilla level) | None direct | None |
| Best Used For | Hair follicle biology | Skin aging, wound | Vasodilatory hair models |
The following reflects findings from published preclinical and clinical safety assessments where available.
Follicle-specific mechanism — dermal papilla targeting more precise than vasodilatory approaches
Topical route well-established — cosmetic research base provides delivery and penetration data
Copper delivery mechanism — endogenous cofactor for key follicle enzymes
Limited formal preclinical data vs GHK-Cu — research base growing but smaller than parent peptide class
