I dyed my hair blue late August/early September of last year. It was a box dye that said it would come out in 30 washes.

I wanted to dye it red next so in November I put a color corrector over the blue because it was still very noticeable. Then I dyed it red and thought that it would just dye over the blue. Well, the red is fading and I STILL see blue/green 🙃🙃. It’s not as noticeable and my bf says he can’t see it but I do so it bothers me 😂 Idk what to do lol I’m gonna have blue in my hair for the rest of my life 💀 I use a 2 in 1 dandruff shampoo which I heard helps get color out of hair faster but idk if it’s working. I think it might be a little bit but it seems to be taking forever :(
