Color Wow Root Cover Up is a temporary hair color in powder form to get rid of your roots in no time. The Color Wow is an innovative mineral powder formula that immediately covers the dark roots in blond hair or hair with highlights. But a gray outgrowth is also completely covered with the dark or light shades. Color Wow helps to keep your color longer and postpones the hairdresser visit for a while. You can go swimming, sweating and sleeping, because the powder does not leave the hair until you wash it with shampoo.
