I've previously had loads of bleached highlights in my brown hair. I had my hair dyed back brown in the salon back in january and I'm really happy with it. The problem is Ive had to go over it so many times since. It fades out after only a few washes. I've been using colour protect shampoos and conditioners but nothing seems to work. I don't want to continue colouring it so much because of the damage and I'm trying to grow it so was wondering if there is any sort of colour depositing shampoos available that work? my hair is a reddy brown but the highlighted bits fade to dull light brown. I remember something by wella called 'shaders' which might work for me but cant seem to find them in the shops. Anyone help???
