Well I have atomic pink hair. And luurve it.
Anyways I dyed some of it, especially my fringe, black about two weeks ago. And it looks like shit now. Not only did I forget about the fact that black and pink looks terribly emo, but it also bleeds like hell and gives my lovely pink hair ugly blackish purple stains 0_O

I just want to get rid of the shit. The shit was "permanent" H&M true black dye, and it's not really as permanent as it said it was, it washes out faster then the pink does, so..

Any ways to wash out or just get rid of the dye very fast? I don't care if the hair goes a bit less pink, I just want the dye oout.
And I'm broke. I've got half a bleaching kit and about one and a half bottle of atomic pink to use, but nothing more... Any clever ideas? :D

Wow who knew H&M did hair dye.

Anyway, I think you need to experiment with a strand test. You might be able to bleach it out pretty easily, especially since your hair was already bleached but expect some damage. The strand test will give you an idea of how much damage to expect.

If it's still running into the pink I would maybe wait a week or two until it stops washing out. You could try applying shampoo to the black hair when it's dry and then rinse it out to remove some of the excess colour.

If the bleaching doesn't take it out easily you'll probably want to opt for a colour remover. L'Oreal Effassor is apparently pretty good and you'll be able to pick that up at a beauty supply shop.

So if I just bleach the black the next time I do my roots, think that will work? At least enough for me to dye pink over it again?

I really couldn't say. Black dye is kind of unpredictable that way. You'd need to do a strand test.
