And another bleaching story!! Help!

Hi everone,

Im new to these boards...so..hello!

Okay, well ill explain my situation....

About a year ago I dyed my naturally dark blonde hair black. (I know..stupid). about a year and a hlaf on it still hadnt gone! It was faded all over and had completely gone from the roots but had left me with a sort of grey colour.
So, I bought a pre lightener (garnier) and it didnt really make a huge difference. So i got another one (thinking i hadnt used enough because I have very thick curly hair). That worked well on the roots and ends but not really on the lengths.
So! I got a blonde hair dye (ice blonde) and dyed my hair. The roots looked great. but the ends were kinda orangy.

As a last resort I bought Jerome Russel Bleach powder kit and bleached the lengths of my hair (and a few mins for the roots).
Now, parts of the legths have gone a brownish orange colour, and some are very yellow. I was going for light blonde!
I left it on for ages, so im confused!

So...after all these dyes and bleach, would it be really bad to bleach again to get the orange out? My hair isnt too damaged (just a bit dry on the ends). Or would a regular dye just remedy this?

Any advice would be great. Im too ashamed and broke to see a professional!
