Disregard my 5 star vote on 'completely covered my gray' I don't have gray hair yet, but there is no way to answer 'not applicable.' I didn't want to give the product a low score. Maybe it's because this is my first try with the coloring comb but this dye was extremely messy for me! I had it all over the floor and counter, not to mention the back of my neck, shoulders, ears and forehead. It was much more runny than other dyes I've used. I didn't think the comb was much easier to use than the normal coloring tip. Yes, it helps with distributing color throughout the sections of hair, but I still combed the color through with my own comb because I could tell there were missed spots. That said the color is gorgeous! When my hair was wet, I was nervous because my roots looked red still . The tips of my hair looked much darker. I had to blow dry to make sure the color was even. It is! There is still SOME red but mostly I see beautiful brunette. I've been trying to correct a process of bad colorings, but I think it's resolved now! Keep in mind, my normal color is fairly dark, so this color might be a little dark for you. It's perfect for me though! My hair has been dull and dry lately. That is all gone now! My hair is shiny and soft. I feel like I have my healthy pretty hair back!
