After rinsing out your color, apply the conditioner supplied with your kit but don't wash your hair. Wait at least a full day, preferably 48 hours, after coloring your hair before you wash it. This will also allow the hair color to completely penetrate your hair shaft. About four to six weeks after coloring your hair, you may need to touch-up your roots. When touching up the roots, don't over-color the ends. Apply conditioner to your ends and then just color the roots and top.
The general rule is to wait four to eight weeks before coloring your hair again but as we just learned itâs not always necessary. If your hair is strong and you use a dye which is not too harsh then you can try to wait a little less than that and everything might still turn out fine. In most cases you can feel if your hair is OK and you can dye it sooner or if itâs damaged and needs to be fixed first. Anyways, regardless of the hair type you have and all other things, thereâs no guarantee that your hair will be severely damaged even if you color it, letâs say, twice in one week.
