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 are 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.
Fine and thin hair is naturally more vulnerable to breakage. Its internal cortex is narrower and has fewer protective cuticle layers, making it prone to frizz, tangles, and structural weakness.
UNBREAKABLE, our strengthening collection, is powered by DURAPLEX FORTIFIER™ technology with a thickening complex—a breakthrough protein matrix that increases strength from within. This system helps reduce breakage with 97% less hair fall* and build fullness from the inside out. This anti breakage conditioner for fine hair optimizes pH and increases internal strength to reinforce the core of fine hair for resilience and elasticity. This hair conditioner also has bond-building power so you can revive styles anytime thanks to reformable bonds. This hair care system also provides cuticle protection to shield against external damage and delivers weightless volume that lasts all day without weighing hair down. Flexible polymers add volume and lift, so hair looks thicker, feels stronger, and styles effortlessly.
