Recently I decided to dye my hair from blonde to my natural dark brown hair color. As us women all know, who have our share of gray/white hair, it's much easier to go blonde than a dark color. Color Wow helps! After 2 weeks, my roots start peering out, lol! All I need is my medium brown Color Wow to keep my secret safe. It comes with a double sided brush which is super easy to use. A little powder goes a long way. I will be a returning customer!
