6. Mixing the colors
Unnatural hair coloring that comes in a tube or a jar is already considered premixed. It is, however, necessary to mix the color with its developer if you bought it on a box. When it comes to mixing hair colors for the two-toned effect, make sure that you are mixing two colors from the same color family. Doing the mix-and-match by yourself could be risky and mixing the wrong colors could make a huge disaster.
