Copper Peptide Hair Growth Conditioner (GHK-Cu)

At HairGenetix, quality and safety come first. Every production batch of our Copper Peptide Hair Growth Products are rigorously tested for purity, consistency, and compliance with premium quality standards. In addition to in-house controls, each batch undergoes independent third-party laboratory testing and is evaluated within controlled clinical study frameworks.

For full transparency, the latest Certificate of Analysis (COA) for the current batch is available below.

Both the Copper Peptide Shampoo and Conditioner contain 0.5% GHK-Cu (copper tripeptide-1). This is a carefully selected, evidence-informed concentration commonly used by high-quality formulators to balance effectiveness, safety, and stability.

Compared to many products on the market that include only trace amounts of copper peptide, 0.5% sits at the upper end of consumer hair-care formulations designed to deliver meaningful biological activity. At this level, GHK-Cu can effectively support scalp regeneration, follicle signaling, and the overall scalp environment needed for healthy hair growth.

GHK-Cu works as a bioactive signaling molecule, meaning more is not necessarily better. Research and formulation science show that concentrations in this range are sufficient to activate key regenerative processes without compromising tolerance or product performance, making it suitable for regular use in both shampoo and conditioner.

Results may vary from person to person, but here’s what many of our customers experience:

1–2 months: Less hair fall - fewer strands in the shower or brush, and a calmer scalp.
2–4 months: Hair looks and feels healthier, with more strength, shine, and volume.
3–6 months: Noticeable improvement in overall density and thickness, often with visible new growth.

Consistent use is key to long-term results.

The Copper Peptide Shampoo is designed for regular use and can be used 3–5 times per week, depending on your hair type and scalp needs. Its gentle, scalp-supporting formula cleans effectively without stripping the scalp barrier, making it suitable for consistent use as part of a hair growth routine.

If you have a sensitive scalp or very dry hair, start with fewer washes and adjust as needed.

Copper Peptide (GHK-Cu) is designed to support hair thinning, shedding, and weakened follicles by improving scalp health and encouraging healthy follicle activity. It works best in cases of early-stage, non-scarring hair loss, where follicles are still active and responsive.

By supporting the biological environment needed for hair growth, copper peptide can help strengthen existing hair and promote natural regrowth over time. While it cannot restore hair in areas where follicles have been permanently damaged or scarred, starting early and using the products consistently offers the greatest benefit.

One bottle typically lasts 4–6 weeks, depending on hair length, thickness, and how often you wash your hair. When used as recommended, only a small amount is needed per wash, making each bottle suitable for regular use as part of a consistent hair care routine.

For best results, use the shampoo and conditioner together and adjust usage based on your individual hair and scalp needs.

Copper peptide (GHK-Cu) works through multiple biological mechanisms that have been explored in laboratory and clinical research. Studies show that GHK-Cu can support hair and scalp health in ways that are relevant to hair growth and thickness:

Stimulates follicle cells: Laboratory research has shown that copper peptide complexes can stimulate human hair follicles to grow longer and support the proliferation of dermal papilla cells, which are key regulators of hair follicle activity.

Supports follicle environment: GHK-Cu may help improve the structural and cellular environment around hair follicles, including promoting factors like vascular endothelial growth factor (VEGF) that support blood flow and nutrient delivery.

Encourages growth phase activity: Some studies and observational findings suggest copper peptide application can help extend the hair’s anagen (growth) phase and reduce regression, which can contribute to fuller-looking hair over time.

Protects scalp health: Copper peptides have documented antioxidant and anti-inflammatory effects that help maintain a healthier scalp environment, reducing stressors that can interfere with normal hair cycling.
