Nexxus Clean & Pure Shampoo for Professional Level Silicon, Sulfate & Paraben Free Detox Hair Care with Lactic Acid, 16.5 fl oz

Hair is made up of protein. Every touch, every treatment, every style you love—it all rewrites your hair’s protein. When protein is damaged, hair’s look and feel is compromised. That’s why Nexxus uses protein science not just to repair hair but to restore its ability to perform. It isn't about one perfect hair day. It's about a lifetime of healthy hair, built strand by strand. When hair faces excessive oiliness, product build-up, or environmental impurities, its protein matrix can be disrupted. Excess sebum and residue block moisture and active ingredients from penetrating deep into the fiber, leaving hair heavy, dull, and hard to style. But harsh cleansing can backfire—stripping essential lipids and making hair tangled and prone to breakage.
