Humectress™ Intensely Hydrating Hair Mask 

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. 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. This HUMECTRESS® Hydrating Mask is part of THERAPPE® and HUMECTRESS®, our ultimate moisture collection, which uses POLYSOFT HYDRATOR™ technology with tri-lipids and protein-strengthening actives to restore that balance. This deep conditioning hair mask for dry hair has a richly concentrated formula that delivers 72-hour moisture, visibly repairs dryness in just one use, and binds hydration deep within hair for lasting softness. This dry hair mask also enhances elasticity for easier styling, smooths and softens strands, targets dry spots, and intensely rehydrates hair by binding moisture within for soft and nourished hair. Nexxus, the protein science behind powerful hair since 1979.
