K18 - Peptide Prep pH Regulating Shampoo 250 ml

• Cleanses while softening the hair's surface: Effective yet safe cleansers break down and remove dirt and oil for optimal nourishment and manageability.
• Designed for daily use: The pH-balanced formula does not disturb the hair fiber or scalp environment and is safe for daily use if needed.
• Creates the ideal foundation for healthy hair: This formula was designed to create an optimal clean surface, free of fillers that would disrupt the balance of the hair and scalp.
• An optimized pH helps maintain the hair cuticle, preventing excess water—which causes damage, dullness, frizz, and tangles—from entering the hair.
