Multi-Peptide Hair Serum — 4% AHK-Cu + 2% GHK-Cu - 50 mL

VPeptide Multi-Peptide Serum for Hair Density is a concentrated topical hair serum formulated around a high-strength dual copper peptide system — featuring 4% AHK-Cu (2 grams) and 2% GHK-Cu (1 gram) — supported by a complementary blend of 12 active peptides and botanicals selected for hair density appearance. Copper peptide complexes, particularly the glycyl-histidyl-lysine copper (GHK-Cu) and alanyl-histidyl-lysine copper (AHK-Cu) tripeptides, are among the most extensively-studied peptide ingredients in cosmetic chemistry, with research literature spanning multiple decades on their interactions with hair follicle dermal papilla biology, copper coordination chemistry, and extracellular matrix protein synthesis in scalp tissue research models. This formulation delivers a salon-strength concentration of these copper peptides in a lightweight, fast-absorbing serum base suitable for daily scalp application. The result is a concentrated cosmetic serum supporting the appearance of thicker, denser, fuller, and healthier-looking hair.

Why This Formula

• 4% AHK-Cu (2 grams per bottle) — Alanyl-Histidyl-Lysine copper tripeptide, the related cosmetic analog of GHK-Cu specifically associated with hair follicle research in cosmetic chemistry literature

• 2% GHK-Cu (1 gram per bottle) — Glycyl-Histidyl-Lysine copper tripeptide, the original copper peptide pioneered in hair and skin cosmetic science

• + 12 active peptides & botanicals — complementary peptide and plant extract complex selected for hair density and scalp appearance

• Salon-strength concentration — substantially higher copper peptide loading than typical mass-market hair serums

• Lightweight serum base — fast-absorbing, non-greasy formulation suitable for daily scalp application

Benefits (Cosmetic Use)

• Supports the appearance of thicker, denser-looking hair

• Helps hair look fuller and more voluminous

• Supports the appearance of healthier-looking scalp and hair

• Lightweight, leave-in formulation suitable for daily use

• Concentrated multi-peptide system for cosmetic hair density support

How to Use

• Apply 4-8 drops directly to dry or towel-dried scalp, focusing on areas where increased density is desired
