Dream Coat Supernatural Spray is the #1 Anti-frizz treatment that waterproofs your hair to stop frizz, even in the worst humidity. The 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: Compresses each strand into a sleek, silky, supple shape and sheathes every strand in a light, imperceptible “raincoat” that repels moisture. This is suitable for all hair types and is ideal for dry, frizz-prone hair or colour-treated hair. Perfect for extensions. Safe for Keratin-treated hair.
