Neurogan GHK-Cu Copper Peptide Hair & Scalp Serum is a lightweight, water-based cosmetic spray that delivers 4% copper peptides (2400mg) to the scalp for daily softening, shine, and comfortable scalp care.

This serum is a minimalist, two-ingredient formula (distilled water and GHK-Cu copper peptides) designed to be used every day. Made in the USA in a GMP-certified facility and third-party lab tested, it absorbs quickly without leaving sticky or oily residue. The spray format targets the scalp directly and is suitable for a wide range of hair textures and routines seeking a simple, fast-absorbing cosmetic scalp treatment.

How does this copper peptide serum fit into a daily hair routine?

Use the spray once daily on a clean or towel-dried scalp, then massage it in to disperse the lightweight solution. Because the formula contains no heavy oils or multiple actives, it layers easily under styling products and won’t weigh hair down.

• Apply directly to scalp and massage for even coverage.
• Absorbs quickly — no greasy or sticky finish.
• Compatible with most shampoos, conditioners, and styling products.
• Designed for daily use to simplify a scalp care routine.

What makes GHK-Cu copper peptides different from other hair ingredients?

GHK-Cu is provided here as a concentrated cosmetic-grade peptide (2400mg, 4% concentration) suspended in distilled water for direct delivery to the scalp. This formulation focuses on a single, well-characterized peptide rather than multiple actives, making it a straightforward option for those who prefer minimal ingredient lists.

• High-concentration GHK-Cu: 2400mg per bottle, 4% copper peptides.
• Water-based suspension for rapid scalp absorption.
• Simple two-ingredient recipe to reduce irritation risk for many users.
• Produced and lab-tested in a GMP-certified U.S. facility for consistency.

Will this serum leave residue or affect styling?

The formula is intentionally lightweight and water-based to avoid buildup on hair and scalp. It dries quickly and should not interfere with blow-drying, heat styling, or most leave-in products when used as directed.

• Non-greasy finish that won’t weigh hair down.
• Suitable for layering under styling products without flaking.
• Designed to be non-sticky for easy daily application.
