How important is it that my hair be unwashed before dyeing it?
Having unwashed hair before a color treatment isn’t always necessary. If you are doing a full lightener on the scalp as the oils will protect your scalp and cause less irritation or tingle …..unwashed hair is a good thing. Normally, hair should be washed within 24-hours prior to the appointment for optimum results and gray coverage. Especially for those who use dry shampoo or a root touch up powder. Remember, formulas have become gentler and are not as harsh as they were in the past, so they work better on a clean hair fiber.
