Nexxus THERAPPE Shampoo For Ultimate Moisture 16.5 oz

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.\ \ Healthy, moisturized hair isn’t just about hydration – it’s about balance. When your hair’s protein-lipid ratio is off, strands become stiff, brittle, dry, and frizzy because the internal structure breaks down and the outer cuticle can’t hold moisture.
