The wonderful thing about hair chalk is that it is temporary color! You remove it by simply washing your hair. While hair chalk is easy to wash out, for the most part, if you’re blonde, you may find it a bit trickier to get all the pigment out of your hair. If you’re having trouble removing the pigment from your hair, try massaging a hair oil into your hair before washing and follow up with a clarifying shampoo to strip out the color.
