Removing dye from bleached hair

Alex

Hello everyone. In October, I had the underneath part of my hair dyed blue and green, and it was great. But now it's faded out and I've been thinking about being bold, and having it dyed a bright pink next (because I really don't like pink, I don't have anything pink in my closet, and decided to face my color fear lmao). Last spring I

had it dyed purple, and it faded over the summer because I was in the pool nearly every day. However, I don't have access to a pool right now. Anyways, the blue is still in my hair, and I would like to know any recommendations to safely strip the color, so the pink will work in my hair, without having to bleach the already bleached hair, and making it extremely weak. My goal is to only have to get my roots bleached.
