It is important for people to wait 48 hours to wash their hair that they have dyed it because washing the hair sooner can cause the color to come out. People who are unhappy with their new hair color can wash their hair before 48 hours has passed to begin trying to remove the hair color.
To help prevent the hair color from fading, it is advised to use shampoos and conditioners specifically formulated for color-treated hair. Using leave-in conditioners and conditioning masques can help keep the hair cuticle sealed, which helps to make the hair color last. It is helpful for people to consult with a hair stylist before dying their hair to get a better idea of what the best colors would be for their skin tone.
