Dye-It-Yourself Hair Color
For a Root Touch-up
If your color looks good but some natural regrowth or a few grays are starting to appear, you don’t have to dye your whole head. Either buy the same kit you originally used or get a root touch-up kit and smooth the dye down just to where your old color starts. For highlights, use a rattail comb to section off only the pieces that need color. Process according to the instructions.
