Amino Bond™ Nourishing Conditioner 

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. Every day, hair faces relentless stress that chips away at its protein structure—the foundation of strength and resilience. Heat styling unravels protein chains, abrasive brushing erodes the cuticle, and UV and pollution exposure oxidizes proteins, leaving strands weakened and fragile. Chemical treatments and color processing go even deeper, breaking disulfide bonds and stripping essential amino acids. Over time, this cumulative damage weakens the cortex, compromises elasticity, and makes hair harder to style, less shiny, and more prone to breakage. AMINO BOND™, our bond-repair collection, is powered by HYDROLINK BONDER™ technology, and a prescriptive blend of five essential amino acids, to reform hydrogen bonds at the core, while FiberShield technology weightlessly repairs damage hot spots throughout the surface of the hair, leaving it smooth and polished. This conditioner for damaged hair results in hair that feels stronger, looks healthier, and moves like it’s never been stressed—without the heavy buildup. Nexxus, the protein science behind powerful hair since 1979.
