Blue hair disaster at 9am, how do I fix this mess?
So I had a client come in last Tuesday at 9am asking for a pastel blue all over. She showed me a photo of this soft baby blue, but her hair was a level 6 brown with some old copper fade. I lifted her to a level 9, toned it, and slapped on the blue. Within 20 minutes it turned this weird swamp green, like a dark teal with muddy patches. I panicked and tried to re-tone it with a violet shampoo, but that just made it worse and patchy. She was super calm about it, just said "I trust you, do what you need to do." I ended up stripping it with a clarifying treatment and doing a demi gloss to even it out. It took 4 hours total and she left happy, but I'm still shook. Has anyone else had blue fade weird on porous spots, and what color remover do you swear by for fixing this type of mess fast?
