I am naturally blonde and used schwartzkopf permanent rose gold for several months. I then used their semi permanent bright pink dye on top for a week before I had to go back to school but it didn't fade as much as it usually does. I'm not allowed dyed hair at school so I used colour B4 hair colour remover which I thought would take my hair back to its usual light blonde but instead it's gone bright blue with parts if it grey. I don't know why it did this but I need a way to get rid of the blue without damaging my hair asap. Can anyone help?
I'm not sure why it went blue with the colour B4, but you could try some of the other fading methods listed on this forum, I recently had some success removing some unexpected green from my hair by using crushed up Vitamin C tablets mixed with Head and Shoulders shampoo. If none of the fading methods work you could try using an adore dye with orange tones diluted with conditioner to counteract the blue, but this will probably result in a muddy brownish colour.
