Are you looking to color your hair yourself? If so, I agree with candibaby that Texture & Tones would be a good brand of color to cover grays. I used it to color over a color mistake I made (yeah I know...too many chemicals). Anyways, if you are able to do it yourself then go ahead, however, if you don't know what you are doing, it's best to have a professional apply your color. HTH.
