GHK-Cu Topical Research Guide

Full name: GHK-Cu Copper Peptide (Topical/Scalp)

The copper-peptide complex applied topically to the scalp to stimulate hair follicle regeneration. GHK-Cu increases follicle size, promotes angiogenesis around follicles, and extends the anagen growth phase through multiple growth factor pathways.

How GHK-Cu Topical Works

Activates genes for hair growth including VEGF, FGF, and nerve growth factor at the follicular level. Stimulates dermal papilla cell proliferation. Extends anagen phase via Wnt/β-catenin pathway activation. Delivers copper for lysyl oxidase (collagen cross-linking).

Dosing Protocol

• Typical dose: 1-2 mg/mL in scalp solution or serum
• Frequency: Daily application
• Duration: 3-6 months minimum
• Route: Topical scalp serum or mesotherapy injection

Reported Benefits

• Follicle stem cell activation
• Increased hair follicle size
• Scalp angiogenesis
• Collagen remodeling in scalp
• Compatible with all other treatments
• Anti-inflammatory for scalp

Potential Side Effects

• Mild scalp tingling
• Blue/green staining (high concentrations)
• Contact sensitivity (rare)
• Generally very well-tolerated
