Palmitoyl Tetrapeptide-20 is a high-purity cosmetic peptide powder for scalp and hair-care formulas. It is designed for leave-on products that help the scalp look healthier and help hair fiber look stronger, better conditioned, and more resilient.

This peptide is a good fit for modern scalp serums, hair tonics, lightweight gels, and leave-on conditioning treatments where formulators want a premium peptide story without making drug-style hair-growth claims.

Product Description: Palmitoyl Tetrapeptide-20 is supplied as a concentrated peptide powder for professional cosmetic development. It can be used in scalp-care, hair-fiber conditioning, and stronger-looking hair concepts, especially when paired with humectants, soothing agents, niacinamide, panthenol, or other hair-care actives.

Usage: Suitable for scalp serum, hair tonic, leave-on hair treatment, gel, lotion, cream, and targeted hair/scalp cosmetic products.
