Washing out hair dye is the process of removing artificial color from your hair. There are a few different ways to do this, depending on the type of dye you used and how long it has been in your hair.
If you have used a semi-permanent or demi-permanent dye, you may be able to wash it out with a clarifying shampoo. These shampoos are designed to remove product buildup and dirt from your hair, and they can also help to fade hair dye. If you have used a permanent hair dye, you will need to use a color remover to wash it out. Color removers are available at most beauty supply stores, and they work by breaking down the dye molecules in your hair.
