Tripeptide-copper complex GHK-Cu (II) transiently improved miniaturized hair follicles and hair density — VialBase Research
medium
- GHK-Cu stimulated hair growth in alopecia patients
- Increased hair follicle size and hair density
- Comparable efficacy to 5% minoxidil in some measures
Summary
Clinical study evaluating topical GHK-Cu for hair growth in patients with hair thinning/alopecia. Participants applied GHK-Cu solution to the scalp over 6 months, with assessments of hair density, follicle size, and hair growth cycle parameters.
Key Findings
- GHK-Cu increased hair follicle size (reversed miniaturization)
- Improved hair density in treated areas
- Effects comparable to 5% minoxidil in some outcome measures
- Proposed mechanism: stimulation of follicle cell proliferation and angiogenesis
- Effects were transient — benefit reduced after discontinuation
- Well-tolerated topically with minimal adverse effects
Methodology
Small clinical study with 48 participants with hair thinning. Topical GHK-Cu applied to affected scalp areas for 6 months. Outcomes assessed via trichoscopy (hair density, follicle diameter), phototrichogram (growth rate), and clinical photography.
Limitations
- Small sample size (n=48)
- Open-label design (no blinding)
- Effects described as transient — durability unclear
- Limited comparator data
- Topical application — does not directly inform on injectable GHK-Cu for hair
Relevance to Content
Supports the hair growth claim for GHK-Cu content. While the evidence is modest, it provides a clinical (not just preclinical) reference for hair-related claims. Should be presented alongside stronger collagen/wound-healing evidence rather than as a standalone hair loss treatment.
