Sleek Polish Anti-Humidity 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—forming a humidity-resistant film on each strand to maintain a sleek look while locking in moisture and preventing over-drying. This advanced system smooths hair, reduces static, and imparts an intense coat of shine, all while shielding against heat up to 450°F and environmental stressors.

Our Sleek Polish Anti-Humidity Spray delivers heat-activated protection and long-lasting, weightless shine. With 72-hour humidity defense and 48-hour frizz control, it helps block moisture to keep styles sleek while smoothing and taming for polished hair. This heat protectant also supports sleek hair care by shielding strands from styling damage. It creates an intense shine finish that lasts, prevents static for a clean, polished look, and adds texture and definition for versatile styling. Whether you’re smoothing strands or creating detailed looks, this spray combines humidity protection, frizz control, and the benefits of a hair heat protectant with a lightweight feel—so your style stays glossy, smooth, and frizz-free no matter what comes your way.

Nexxus, the protein science behind powerful hair since 1979.
