If you discount my very gray and thin hair, I am a brunette and have had good coverage with Nutreese. I like it as it seems less harsh than others. I liked the Olia but it didn't cover the gray as well. I've been doing my own for almost a year now because of cost, and it has taken a lot of trial and error to find the best one for my particular hair. You may have to do the same thing.....every head reacts differently to the chemicals in the dyes......
