Bad hair...tipp

Well, im no expert on hair as ive had a few disasters myself but i asked my hairdresser what i should do and she suggested getting a semi permanent lighter colour so that your hair can go lighter gradually and not straight from the dark colour to the light colour. then after that has washed out a few times go for the same colour but maybe a permanent colour...
Want some real advise? i'd get it done at the hairdresers that way they can get it just how you want it and if they screw it up you can blame them not yourself!
