Oh christ this is awful. 15 years old, we started letting her dye her hair at 13 as long as it was black/brown/blonde/red etc and not crazy colours. She's been black, dark brown, red, and brown with a purple tinge which was her most recent colour about 3 months ago. She has always done it herself with a home dye kit and we've avoided any disasters up until now. She decided she wanted to go full on platinum blonde because that seems to be the thing right now and we're going on holiday on Sunday. She goes upstairs to do it and an hour later emerges in tears after drying her hair because it's orange. And god it really is awful, there are tinges of green and red in there. We are going abroad in 2 days and all of the hair salons are saying they can't get us in with such short notice but they'll call if they get a cancellation! Does anyone have any advice? I've bought her some chocolate brown hair dye (she won't go out) because I feel dark colours will cover it all up but I don't want to use it yet as I have no idea what I'm doing!
