I need to know EXACT color name and number and the right ratios of color and developer to make my naturally black roots go to a med/dark brown color. All supplies will come from professional beauty store, not a kit. mssherryk. Please give eaxact formula

I will try to be more pacific with you. You will need to use a half-bottle of peroxide developer with your desired color (medium brown) which you will find separately at a beauty supply store. You can also buy separate hair coloring application bottles to mix the color mixtures evenly and then apply it to your hair. You've asked the same question more than once. Obviously, you have no experience in hair dyeing, so you should definitely let a professional or someone who's knowledgeable in hair coloring to color your hair for you.
