Question: Can a self-tanner dye my hair?
Because hair is porous, it can easily absorb the dihydroxyacetone used in self-tanners. Dihydroxyacetone is the chemical in self-tanners responsible for the tinting process. To avoid having your hair turn orangey, use a cotton ball or swab to apply self-tanner around your hairline. You can also put your hair up in a shower cap for added protection. If you do happen to get self-tanner in your hair, don’t worry it is not permanent. However, it will take a few shampoos before it does come out.
