COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Shampoo gently cleanses damaged hair and a sensitive scalp, moisturizes and soothes the sensitive scalp and hair, strengthens damaged hair fibers, and leaves hair silky smooth, soft, and shiny. The patented PEPTIDE-132™ technology works at the hair fiber structure level, restoring damaged bonds, replenishing the hair’s protein content, and strengthening keratin bonds. Biotin, panthenol, niacinamide, and vitamin E soothe and care for both the hair and scalp. Caffeine, zinc PCA, and piroctone olamine soothe the sensitive scalp, balance sebum production, and reduce discomfort and dandruff-related concerns. Suitable for hair with varying levels of damage, from mild dryness to heavily chemically treated and damaged hair. Also suitable for an itchy, flaky, and oily scalp.
