What distinguishes Color Wow from other hair care brands? Color Wow is the ingredient police when it comes to hair colour, being the first to outlaw "colour corrupters" present in most haircare and style products. Over 60 substances have been discovered and prohibited by Color Wow because they can stain and alter hair colour. Every composition is based on groundbreaking, exclusive Color Wow Lab technology. Not tested on animals, No parabens, No sulfates and No toxic ingredients
