Prep & Protect Heat Defense Spray 

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 style, built strand by strand. That’s where STYLEPROTECT™ Technology comes in—locking in moisture while creating a flexible shield on each strand to protect against heat up to 450°F and environmental stressors. This advanced system adds softness, shine, and frizz control while helping prevent static and protecting from humidity, so your style stays smooth and protected. Our Prep & Protect Heat Defense Spray delivers a weightless conditioning mist that detangles, softens, and shields hair from blow dryers and irons. This heat protectant spray leaves hair smooth, polished, and frizz-free for sleek and controlled styles with no sticky buildup or flakes. This nourishing heat spray also makes hair easier to manage, as this heat protection spray with a color-safe formula detangles hair instantly—helping your style feel as smooth, polished, and healthy as it looks. Nexxus, the protein science behind powerful hair since 1979.
