The Color Strand Test is the best way to preview a color and avoid undesirable results. We recommend that you test the color on a part of your hair that contains the colors you want to cover. Think of this as a dress rehearsal—time yourself as if you were coloring your whole head, but don’t mix up the whole kit, only a small portion is necessary.
