How can you darken bleached hair?

If your hair is bleached blonde in order for you to go darker and not have your hair turn green you will want to dye it red first then use a darker brown to go over it. Or you can dye it a deep brown with a red base. Remember though when you dye it that you will want to pick a color darker than you actually want your hair to look bc it WILL fade quickly. Probably 2 weeks after you dye it you will want to re do it again to acheive the color you want. hope this helps
