It is vital that you wash and condition your hair before coloring it. Perform this ritually the night before your appointment, as this allows your natural oils to reside on your hair upon coloring.
The main goal before you get your hair colored is to reduce any debris or product on the follicles, so that the color can seep into your hair effortlessly. Shampooing your hair is important, as it reduces the bacteria and product that your hair absorbs during the day. Condition your hair to keep it manageable, soft and flexible for the stylist the next day at the salon.
