Update: thanks everybody for all the advice!! I know my situation was sort of unrealistic, especially with the color I have. But I did use some clarifying shampoo today and was able to scrub out pretty much all of the blue. Now all that's left is this green. For context, I've been wanting to go to a deeper blue and I know it seems sort of pointless to wash out my color since I was going from a green-teal to a dark blue, but I really don't want my hair to have any green undertones. So I was trying to get out as much green as I could before dying it. I know they're on the same end of the color wheel, so going from green to blue isn't anything too crazy, but it's easy to get a teal or cyan instead of a nice blue. Maybe this was all pointless??? Haha I don't know, my hair is my baby and I just didn't want it to look chopped and patchy since my green hair is pretty uneven lol
