Product Details

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. Our HUMECTRESS® 20 IN 1 Leave-In Conditioner Perfector Spray is a proteomic multi-benefit spray that delivers 20 benefits in one. It 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 and strengthen hair. This hair conditioner leave in spray helps rebuild your hair’s structure and lock in moisture, while also priming and protecting against heat and humidity, boosting shine and silkiness, and fighting frizz for instant smooth, soft, and resilient hair—no matter your texture. Nexxus, the protein science behind powerful hair since 1979.

Use the hair protector on either dry or damp hair. Apply to your hair before blow drying, air drying, or styling. Gently comb through hair to distribute the product evenly. Works best when paired with the Therappe Shampoo and Humectress Conditioner.

Humectress leave-in spray for all hair types is a complete 20 in 1 multi-benefit spray that primes, nourishes, and strengthens hair with every use.
