My DD has used one of these supposedly "wash out in 2 washes" hair colours, but unfortunately it's lingering in her hair in an unattractive grey/purple hue! She has in the past (when her hair went green from the swimming pool on holiday!) used something that I got from Boots that wasn't a colour stripper, like Colour B 4, but more of a colour corrector, had vit c in it. But I can't find it in store or on the website now and all that we can remember was it came in a white and gold box.
Does anyone know what this could be or recommend anything else that could help shift this colour, please. Her hair had been permanently coloured a light blond at the hairdressers, so I don't want anything too harsh, just a colour corrector not a colour stripper. Thanks
