Neurogan GHK-Cu Copper Peptide Hair & Scalp Serum — 4% (2400mg), Water-Based, Fast-Absorbing for Softness & Shine

This single-purpose serum uses a simple, two-ingredient formula—distilled water and GHK-Cu copper peptides—so you get a clean, fast-absorbing product made in the USA. Designed for daily use, the spray targets the scalp and hair surface to help maintain comfortable-feeling skin and smoother-feeling strands. It’s third-party lab verified and produced in a GMP-certified San Diego facility, making it an option for shoppers who prefer minimal, transparent formulations.

How does this serum fit into my daily hair routine?

Use the spray once a day directly on the scalp and massage gently to distribute. Because the formula is water-based and lightweight, it absorbs quickly and won’t leave a sticky or oily finish—so it can be used alone or layered with styling products.

• Daily application: spray on scalp once per day.
• Fast absorption: water-based texture resists residue.
• Layer-friendly: compatible with other hair and styling products.

What makes copper peptides a chosen ingredient here?

Neurogan uses GHK-Cu copper peptides at a 4% concentration (2400mg) for a focused, straightforward formula. Copper peptides are commonly used in cosmetic products for supporting the appearance of healthier-looking hair and maintaining a balanced scalp surface when used as part of a cosmetic routine.

• Concentration: 4% GHK-Cu, clearly stated strength.
• Minimalist base: distilled water plus copper peptides only.
• Cosmetic use: formulated for topical scalp and hair application.

Which hair types and scalp concerns is this suitable for?

The serum’s lightweight, water-based design suits a wide range of hair textures and can be incorporated into everyday care for sensitive or dry-feeling scalps. Because the product is cosmetic and non-greasy, it’s useful for people who want simple scalp hydration and reduced surface buildup from heavier oils.

• Many hair types: suitable from fine to thicker textures.
• Dry or dry-feeling scalps: provides light surface moisture.
• Non-greasy finish: avoids sticky or oily residue after use.

How is quality verified and where is it made?

Neurogan manufactures this serum in their GMP-certified facility in San Diego and conducts third-party laboratory testing for purity and potency. The brand emphasizes transparent production and family-owned stewardship, so packaging and testing information are available for shoppers seeking traceable manufacturing practices.
