I have light brown hair, and I bleached parts platinum (Blonde Brilliance) to dye them green. Once it grew out a little, I bleached it again (it was the wrong shade of green anyway) and redyed it a darker green. (SpecialFX Iguana)
The second bleaching took the yellowish tint out of the hair from the first dye, and changed it more of a sea-foam color in some places, other places a little greener, and white in other places, like the new roots. Then I applied the darker shade, which had more blue in it.

Now I am applying for a new job and don't want to look so cool. :D Ahhh good ole' Corporate America. :rolleyes:
I've been washing at least once a day with dandruff shampoo, and a few times with dish soap to remove the green. It has faded considerably, but I'm thinking I'll need to dye it a darker color to cover the green.

Do I need to bleach those green parts again to dye over it? Which is better, bleach or a color remover/ color stripper? (I can't afford a salon so I'll be doing this myself.)
Or can I just dye over the highlighter shade of green it is now if I use a darker brown? Would a redder dye help balance the green, or can I just do my whole head one color and hope it balances itself. I'm expecting a little variation, but just don't want the green to show though.
Heeeelp my interview is this week!:confused:
Thanks.

You will need to strip out the green. Perhaps with a colour remover? As it's faded quite a lot. Hopefully that will lift out the lovely green :p
Then once that's been lifted out, apply the red toner (can be a temporary or semi colour), then the brown on top.

I just think it would be best for the green to come out, because when you add colour to the hair, it just builds up inside the hair.

Let me know if you decide to go for it and let me know how it turns out. :)
