i would say hair dye remover if you wanna get it out quickly or you can use a clarifying shampoo a few times if u don't want to use that

oh also has your pink faded out? because i would recommend using a clarifying shampoo or something to fade it to a pale pink if it's still a rich pink before using the green dye!

oh nah i wouldn't use a spray, i'd go with any semi permanent light or mint green dye and let it process for like 10 minutes maximum

hair dye remover and/or you can straight up dye it with a light green to cancel out the pink
