How to use shades eq kickers with other permanent haircolors?

To use Shades EQ kickers with other permanent haircolors, first mix the desired permanent color with the appropriate developer as per the manufacturer's instructions. Then, add a small amount of the kicker (typically 1/4 to 1/2 of the total mixture) to enhance the tone or correct underlying pigments. It's essential to perform a strand test to ensure the desired result before applying the mixture to the entire head. Finally, follow the processing time recommended for the permanent color while keeping in mind that the kicker may influence the overall outcome.
