Hy Volume 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.\ \ Flat, lifeless hair often stems from internal damage, excess sebum, or a naturally fine texture—leaving strands unable to hold volume or resist humidity. Fine hair has a smaller cortex, the part responsible for strength, making it harder to maintain lift. Without the right foundation, strands collapse and lay flat against each other, leaving hair limp and style-resistant.\ \ HY-VOLUME™, our volumizing regimen, is powered by MAGNITUBE VOLUMIZER™ technology with hyaluronic acid to plump and expand fibers from root to tip. This three-step hair care system includes a silicon and sulfate free shampoo, a hair conditioner, and a foam. These volume hair products strengthen the inner protein matrix for lasting lift, increase internal strength, and shield against humidity—so hair feels thicker, weightless, bouncier, and full of movement for up to 48 hours.\ \ Nexxus, the protein science behind powerful hair since 1979.
