Hey everyone, help is very much needed. So here's my problem:

My natural color is brown. I went blonde about 3months ago then my roots were growing and I grew tired of the blonde and me being impatience didn't go to a salon to get it dyed a darker color. I bought Garniers 100% deep brown and colored it myself but then people at work pointed out the green tints in my hair (I forgot if you go from a blonde to a dark brunette it gives off a green tint) then someone told me to use a ash brown which I think made the green show more. Now I was thinking to use COLOR Oops. However as I'm reading the box it says that it will take out the darker shade not the ligt shade. So here are a couple of questions:

Does this mean that it will NOT take out the blonde that was there before I dyed it brown?

And I have long hair down to the middle of my back. Would I need 1 application bottle or 2?

Thanks! Any help from anyone who used Color Oops is greatly appreciated!
