Regular but NC'd for this...HELLLLP
I've been blonde before, I'm naturally ginger,wanted to dye it back to blonde. Used Jerome Russell B Blonder maxximum lift kit like I always do - it was AGONY on my scalp and I don't know why. Left it to develop for about an hour, then washed it out. THIS HAPPENED.
HELP. Someone please tell me how to fix this, bearing in mind I only have a Tesco extra near me that's open at all. How do I fix this?! It's a disaster!
