sounds like you left it on too long - was it an ash color? I would call the 1800 number on the box and get them to help you, or have a hair stylist advise you. If it wasn't a permanent color, sometimes a clarifying shampoo can help get it out but where this is your hair - I wouldn't mess about. Ask a pro. I do know it can be fixed. All those little old ladies with the purple hair used ash colors and they were left on too long. Good luck :)
