I am a natural blonde and have been dying my hair golden blonde for the past year. I decided to dye my hair light brown with highlights on top. Didn't like the brown so I used color oops. I then dyed my hair medium blonde and it turned greenish, brown and gray. I used color oops again. Now my hair is blonder but still pretty green. If I apply effasol will it correct the green or will my hair fall out?

Moved from forum helps to hair

I love green, you will stand out, well I did move your post for you, sure you will get some help here

From what I know effasol is a colour remover? Don't think it will remove the green tone. You will need to use a red toner to counteract the green. But be careful, sometimes very porous hair grabs onto the red and won't wash away!
If you can try get it corrected from a professional. :)
