Product Overview
K18 Peptide Prep - pH Maintenance Shampoo 250ml A cleansing shampoo microdosed with the patented K18PeptideTM. Powerful yet non-stripping formula is designed with an optimized pH that is safe enough for everyday use. Benefits: Cleanses while smoothing the hair surface: Effective yet safe cleansers break down and remove dirt + oil for optimal nourishment and manageability.
Designed for daily use: pH-balanced formula doesn’t disrupt the hair fiber or scalp environment and is safe to use daily if needed. Creates the ideal foundation for healthy hair: This formula was engineered to create an optimal clean canvas without any fillers to coat or disrupt the hair and scalp equilibrium. Less is more formulation delivers a superior clean without compromise: Optimized pH keeps the cuticle closed during washing and protects hair’s natural moisture levels for a smooth hair result.

Plant-derived surfactants create high foaming + cleansing power without being harsh or leaving buildup behind on hair or scalp. K18Peptide works as a protective shield to reduce protein loss that can occur during washing to keep hair feeling soft, strong, healthy and clean. Ingredients: Water (Aqua) (Eau), Sodium C14-16 Olefin Sulfonate, Cocamidopropyl Betaine, Sodium Methyl 2-Sulfolaurate, Sodium Lauryl Sulfoacetate, sh-Oligopeptide-78, Panthenol, Glycerin, Sodium Phytate, Guar Hydroxypropyltrimonium Chloride, Disodium 2-Sulfolaurate, Caprylyl Glycol, Caprylhydroxamic Acid, Benzoic Acid, Citric Acid, Sodium Hydroxide, Fragrance (Parfum), Limonene.
