| If your hair is color-treated and you use a darker, it will grab the color you use quickly, making your hair darker. To neutralize the red tones in your hair, you can use a green-base ash hair coloring product in dark ash brown or ash brown. In order to go from dark brown to light brown, you may have to use some kind of hair lightening product to achieve results. This can be done by using a higher volume-peroxide developer with your selected color in equal parts, however, it could produce an unpleasant shade. So it would be best to pre-lighten your hair a level lighter than the color you want and then apply the desired color. If you think brown hair doesn't suit your skin tone, and want to go back to blonde, please go to a salon and have a corrective color done. |
