HAIR DILLEMA- overbleached hair gone green

Like this:

Anyway, the bleach was left on a little too long, and the final product was a pale yellow color, so close to WHITE! I flat ironed my hair a lot from then on, because if not, it would've been a big messy BUSH. So I think that's contributed to the damaging of my hair... So about 5 months later, about an inch or more of my roots grew out, and I went to a salon again because I wanted my natural color back. All she did was recolor over my whole head, no color correction! So my hair was dark brown. And then, the color faded within a few days. The roots were fine, but the bleached part started to fade to a GREENish color! I just left it alone, and in September 08, I tried coloring it over myself with a brown color. When I washed my hair that night, my roots were the color I wanted, but again the bleached part showed through and was greener than before.

 

& now it looks like this!

 

But I've heard of fillers and all of that. Would that work for my hair situation? What color/kind of filler would I use for my hair, and would I just use it on the bleached-that-turned-green part and not my roots, and then just color the whole thing brown?!

 

confusing and frustrating!

 

 

Sorry so much questions. I'm tired of calling salons and asking, because they don't seem to be much help at all!
