Don't Wash Your Hair Beforehand The natural oils on your scalp actually serve as a protective barrier to guard against irritation from the chemicals in the hair dye, so you want them there before you apply dye. Do not wash your hair before applying color, this will irritate your scalp and can make it feel sore. The hair should be clean of product but not of your natural oils, as it acts as a protectant. If your hair is particularly dirty, however, make sure that you wash your hair at least 24 hours before reaching for the box—doing so will help the dye penetrate without being too clean and vulnerable to the effects of the dye. A clarifying shampoo is recommended to remove any styling products that you have used on your hair. Prior to reaching for your hair dye, make sure to thoroughly detangle your hair. This will prevent any knots or tangles from creating an uneven application—plus, you don't want to worry about any detangling mid-application. Use a wide-tooth comb for this and gently work your way from your ends to your roots.
