Neurogan GHK-Cu Copper Peptide Hair & Scalp Serum — 4% (2400mg), Water-Based Spray for Lightweight Hydration & Shine

Neurogan GHK-Cu Copper Peptide Hair & Scalp Serum is a lightweight, water-based spray containing distilled water and 4% GHK-Cu copper peptides (2400mg) designed to refresh the scalp and leave hair feeling soft and shiny.

This formula is intentionally simple: distilled water plus a concentrated dose of GHK-Cu copper peptides, blended in a fast-absorbing, non-greasy base. Made in the USA in a GMP-certified facility and third-party lab tested, the serum focuses on daily scalp comfort and lightweight hydration without heavy residues. It’s packaged as an easy-to-use spray for targeted application and quick absorption.

How do I use this spray in my daily routine?

Apply the serum once daily directly to the scalp, focusing on areas where you want lightweight hydration and a refreshed feel. A gentle massage helps distribute the product and supports even absorption. You can use it on damp or dry hair and continue with your usual styling products afterward.

• Spray directly onto scalp once daily.
• Massage gently for even coverage and absorption.
• Works on damp or dry hair; follows with styling as desired.

What makes the ingredient list so minimal, and why does that matter?

The serum uses only distilled water and GHK-Cu copper peptides to reduce potential irritants and simplify care. This pared-down approach limits unnecessary additives and fragrances, making it suitable for daily use for many hair types. The result is a clear, fast-absorbing product that won’t leave sticky or oily residues.

• Two-ingredient formula: distilled water and GHK-Cu peptides.
• Water-based for fast absorption and light feel.
• No heavy oils, silicones, or fragrances to weigh hair down.

How will this serum fit different hair types and concerns?

Because it’s lightweight and water-based, the spray integrates easily into routines for fine, medium, and thicker hair textures. It’s formulated for daily scalp refreshment and light strand hydration rather than heavy conditioning. If you’re looking for a simple, non-greasy boost to scalp comfort and hair sheen, this product is intended for that purpose.

• Suitable for a wide range of hair textures and daily use.
• Light hydration without coating strands or adding weight.
• Designed to leave hair feeling softer and shinier after absorption.
