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. The key? Purify without compromise and replenish what hair needs to stay strong. CLEAN & PURE, our detox collection, is powered by CLARIFIX BALANCER technology with lactic acid to deeply cleanse hair from root to tip for reduction of buildup and to rebalance optimal lipid levels. This shampoo and conditioner hair care system strengthens proteins at the core while restoring natural shine and movement—so hair feels clean, soft, and healthy without the heavy buildup. Nexxus, the protein science behind powerful hair since 1979.
