Princess, semi-permanent hair color is a type of hair color that will last for anywhere from 6 to 8 shampoos or more. However, if a black semi-permanent color is applied to porous hair or light hair, the color may leave a permanent tint. I suggest that you go to the salon a have them fix your hair. At the salon, they will strip the black hair dye and then apply a color that's close to your natural hair color.
