Skin Pharmacology and Applied Skin Physiology · Vol. 12(1–2) · pp. 101–110 · 1999
Demonstrates that GHK-Cu stimulates hair follicle enlargement and increases hair growth in animal models. The copper peptide promotes follicle size, increases hair shaft diameter, and extends the anagen (growth) phase. These findings support the use of GHK-Cu in topical formulations for hair density improvement.

Key Findings
GHK-Cu increased hair follicle size by 40% in treated animals
Extended the anagen (active growth) phase of the hair cycle
Increased hair shaft diameter and overall hair density
Topical application showed comparable efficacy to minoxidil in some measures
No significant adverse effects observed at therapeutic concentrations
Methodology
In vivo hair growth studies in stump-tailed macaques (a validated model for androgenetic alopecia) with topical GHK-Cu application. Includes histological analysis of follicle size and cycle phase.
Limitations
Animal model; human clinical data limited. Optimal concentration and formulation for human use not established.
