This works just like most dry shampoos and sprays a powdery like substance on your roots but the difference is it is colored so it doesn't look like your hair is gray. If you think it's making your hair look worse the color you're using is too dark for your hair shade.
It goes on dry. It's cold though, so it may feel wet at first but it's not. Just be sure to not spray too close or you will have white on your hair lol. This stuff does work good though. I use it and won't use any other brands anymore.
