OLAPLEX® Clarifying Shampoo N°4C is an exceptional deep cleansing shampoo designed to restore healthy hair. Its innovative Bond Maintenance® formula removes mineral build-up, heavy metals, chlorine and product residues that make healthy hair dry, stubborn and greasy. Unlike aggressive detox shampoos, N°4C is sulphate-free and has a pH-neutral formula, so it provides gentle yet effective cleansing without stripping the hair of its natural moisture. It also contains OLAPLEX® Bond Building Technology™ to deeply cleanse the scalp. It noticeably increases hair shine, revives dull colours and eliminates build-up. N°4C Clarifying Shampoo also keeps the scalp hydrated and healthy for long-lasting results.
