From the Manufacturer:
ColorWow Dream Coat Supernatural Spray is the #1 Anti-frizz treatment waterproofs your hair to stop frizz, even in the worst humidity. Advanced anti-frizz formula leaves hair super glossy, glassy, ultra smooth. Groundbreaking humidity-blocking technology stops moisture from wrecking your style. Ultra-light frizz control spray feels like nothing is on the hair. Economical. Results last through 3-4 shampoos.
Dream Coat uses a ground-breaking, heat-activated polymer technology that is feather-light. It will not weigh hair down or leave it greasy.
When activated by the heat of your blow dryer along with light tension from a brush, Dream Coat forms an invisible, hydrophobic matrix that does two things:
1) Compresses each strand into a sleek, silky, supple shape
2) Sheathes every strand in a light, imperceptible “raincoat” that repels moisture.
