If you try to apply color over hair that’s already been dyed, it’s only going to get darker. To dye over a dark hair dye, you can choose a simple method, such as adding highlights or color sprays to your hair. You can also lift the color using special shampoos or color removers — this method will work for lightening your hair color just a few shades. For a more drastic color change, you can bleach your hair and apply a new color to achieve your desired look, making sure to use extra caution so that your hair doesn’t become super damaged.
