Color Wow Extra Strength Dream Coat is a powerful, ultra-moisturising, anti-frizz treatment that keeps dry/dehydrated and coily/curly hair glassy-smooth, straight and frizz-resistant through 3-4 shampoos. Award-winning waterproofing technology blocks out humidity and locks in moisture to prevent smooth, straight styles from reverting back to naturally curly or frizzy texture. It fills dry, porous, frizz-prone hair with internal moisture which negates this hair type’s natural urge to pull in atmospheric moisture (humidity) that makes hair puff and swell. Delivers long-lasting results for hair that has been blow-dried smooth and sleek, thanks to ultra-powerful (totally imperceptible) flex-elastic polymers that seal down the cuticle, making the hair silky smooth, waterproof and tightly hold the hair smooth and straight. Suitable for extremely dry/dehydrated hair, porous hair, and curly/coily hair. Safe for Keratin-treated hair.
