26%-50% HAIR REGROWTH
Research into Copper Peptides - specifically AHK-Cu (Alanine-Histidine-Lysine) and GHK-Cu (Glycyl-Histidine-Lysine) has gained significant traction in dermatology. While they are often marketed as a "miracle" alternative, the professional and clinical landscape also reveals a mix of robust lab-based evidence.
This page shows the key clinical and professional trials, including quantifiable benefits and publication links.
Typical, evidence-backed benefits include:
- Hair Regrowth: +26% to +50% (5 months)
- Hair Density: +11.7% to +25.2% (3–6 Months)
- Reduced Shedding: -20%
- Anagen Phase: +7.5%
- Inflammatory Reduction: -30%
- Acccelerted Growth: +50%
See below for quantified conclusions and full Clinical Studies.
The Human Hair Follicle "In Vitro" Study (2007)
Study: The effect of tripeptide-copper complex on human hair growth in vitro
Publication: Archives of Pharmacal Research (2007)
This study is the cornerstone of copper peptide research in trichology, specifically focusing on AHK-Cu. It demonstrated how the peptide physically interacts with the "command center" of the hair follicle.
Focus: AHK-Cu (Alanine-Histidine-Lysine Copper)
Findings: Researchers cultured human scalp follicles and treated them with AHK-Cu. They observed a significant stimulation of hair follicle elongation.
Mechanism: The peptide promoted the proliferation of Dermal Papilla Cells (DPCs), which are the "command center" for hair growth. It also reduced the rate of DPC apoptosis (cell death) and increased the ratio of Bcl-2/Bax (pro-survival markers).
Evidence Quality: Very High. There is no doubt that copper peptides stimulate human hair cells in a controlled lab environment.
Quantifiable Benefits:
- Cell Proliferation: Significant increase in the proliferation of Dermal Papilla Cells (DPCs) compared to untreated controls.
- Apoptosis Reduction: A measurable decrease in the rate of follicle cell death (apoptosis) by elevating the Bcl-2/Bax ratio.
- Hair Elongation: Treatment stimulated hair follicle elongation in cultured human scalp hair follicles.
The "MDCT" Combination Protocol Study (2025)
This is a very recent study investigating a high-delivery method (microneedling/micro-infusion) using copper peptides as a synergistic agent alongside traditional supplements.
Researcher: Dr. Loren Pickart (The discoverer of GHK-Cu)
Focus: GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper)
Publication: JAAD International (Official Journal of the American Academy of Dermatology)
Findings: Pickart's research demonstrated that copper peptides could enlarge hair follicle size. He noted that follicular "miniaturization" (the shrinking of follicles seen in pattern baldness) could potentially be reversed by these peptides.
Comparison: Some of his earlier work suggested that the effectiveness of copper peptides in increasing follicle size was comparable to that of 5% Minoxidil.
Quantifiable Benefits
After 5 monthly sessions:
35.5% Median Regrowth: Patients saw a median 35.5% regrowth in the top scalp area as assessed by AI and blinded evaluators.
30% Area Coverage: A minimum of 30% improvement in hair coverage was observed across the majority of the treatment group.
High Needle Exposure Efficiency: The addition of copper peptides to the 2mm needle delivery protocol yielded superior results compared to standard topical applications.
The "Hair Count" Human Trial (2018)
In a rigorous 6-month human trial, researchers evaluated the efficacy of a GHK-peptide complex (the primary active component of copper peptides) against a placebo. The results demonstrated that copper peptides do more than just "condition" the hair—they actively drive new growth and density.
The Verdict: This trial confirms that GHK-peptides are a clinically proven solution for increasing hair count and density without the side effects often associated with pharmaceutical hair loss products.
Study: Efficacy of GHK-Peptide Complex on Hair Growth
Publication: Journal of Applied Pharmaceutical Science (2018)
Quantifiable Benefits
The Results at 6 Months:
7.4x Greater Hair Count: Patients using the peptide complex saw an average increase of +71.5 hairs/cm², compared to only +9.6 hairs/cm² in the placebo group.
Visible Density & Thickness: Over 26.7% of participants reported "Good-to-Excellent" satisfaction, specifically noting visible improvements in hair shaft thickness and overall scalp coverage.
100% Safety Profile: The study recorded zero adverse events, confirming that copper peptides provide a powerful, non-irritating alternative to traditional chemical treatments.
