During the dyeing process, coat lighter hair in conditioner to protect it. The conditioner will act as a shield when you rinse the dye itself out, lessening the unwanted contact that the dye has with your hair. Another option is to cover the dyed sections with foil or plastic. Then, rinse the darkest sections of your hair first to prevent them from bleeding onto the lighter sections. You will need to shampoo and condition your hair right after dyeing it to get the dye residue out of your hair, but then wait 48 hours to wash it again. Washing it too much too early can dislodge the coloring agents. Though it wouldn’t affect the vividness of your dyed hair too much, those colors can easily find their way into the parts of your hair where you don’t want them.  You can use warm water to wash your hair, just make sure it is not hot. Hot water opens up the cuticles in your hair and lets some of the dye out; run-off here will be particularly noticeable when you’re trying to keep the colors in your hair separate from one another.  Wear a shower cap or pin your hair up out the way to protect it on days you don’t want to wash your hair. You’ll want to use shampoo that’s designed for color-treated hair, to better keep all your colors from bleeding. If your hair’s getting too dirty with fewer shampoos from fewer showers, try out a dry shampoo to keep your hair clean in those interim periods. Or, you can also try rinsing and conditioning your hair to get rid of excess oils and dirt between shampoos.
