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.
