THERAPPE® and HUMECTRESS® Advanced Hydration Regimen Pack 

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. That's why luxuriously hydrating actives are essential. They balance hydration to the optimal level, instantly restoring fluidity and responsiveness to dehydrated and brittle hair proteins for touchably softer, smoother, healthier strands.

THERAPPE® and HUMECTRESS®, our advanced hydration collection, uses POLYSOFT HYDRATOR™ technology with tri-lipids, glycerin, and an amino acid compound to strengthen proteins and restore balance. It seals the cuticle to lock in hydration and visibly combats dryness in just one use. Our advanced shampoo and conditioner also deliver a moisture boost for softness and manageability, detangles hair and reduces frizz for polished strands. This shampoo for dry hair and conditioner for dry hair helps rebuild your hair’s structure and lock in moisture, so hair feels soft, smooth, and resilient—no matter your texture.
