My daughter decided to color her black how can I get rid of this awful color:

Ma'am, you didn't mention your daughter's previous hair color or what her natural color was. Black hair dye is the hardest color to remove. If your daughter's hair was more than 3 shades lighter than her current hair color, then it is necessary to remove all the color from the hair in order to achieve the correct color. Do not attempt to fix it yourself, it could make matter worse. I recommend that you take her to a salon for a color correction. A stylist can strip the color and try to match her natural color as close as possible.
