I've growing out my colour & having regular cuts to speed up the process. But- my hairdresser put a toner/rinse through it on Saturday to help blend my natural white with the last remaining couple of inches of coloured hair. I don't like it, my natural white has gone blue/ grey. She told me it would wash out in about 3 washes , needless to say it hasn't. Can anyone advise me how to remove please?!
