Product details
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 you style, color, or even brush your hair, vital proteins and amino acids start to break down—weakening the fiber and dulling its shine. Powered by KRT™ Keratin Resistance Therapy with liquid crystal serine amino acids, the crystallizer uses advanced proteomics to pinpoint and restore what’s lost, rebuilding your hair’s internal structure and reinforcing its protective cuticle layer for lasting strength and luminosity. It seals the outer layer to restore elasticity—so hair is shiny, soft, resilient, and ready to bounce back with every style. Our KERAPHIX Liquid Crystallizer Reconstructive Leave-In Treatment is your go-to for repairing damage and future-proofing your strands. This damaged hair treatment for damaged hair strengthens bonds to repair and resist visible damage and hair breakage for hair that is 34X stronger* and restored to be as strong as virgin hair**. The result of this hair strengthening treatment is weightless hydration that detangles and enhances manageability for effortless care and styling. It’s like a reset button for your hair—bringing back fresh, soft, fluid movement and a high-gloss finish, no matter how often you style. Nexxus, the protein science behind powerful hair since 1979. *vs. non-conditioning shampoo **Based on a breakage study with bleached treated hair vs. virgin hair
