Color Wow Dream Coat Supernatural Spray is the #1 anti-frizz treatment that waterproofs your hair to stop frizz, even in the worst humidity. Activated by heat, effects last through 3 to 4 shampoos. Inspired by textile technology, this humidity-proofing formula acts like a raincoat. It wraps each strand in an imperceptible, water-resistant barrier that causes water to bead up and roll off. So you get silky, glossy, glassy, frizz-free hair no matter the weather!
