Manic Panic, maybe?
I used that on my hair a looooong time ago, it's supposed to be 1 week temporary wash-out, but since the ends of my hair were sooooo blonde, it stained my hair. I had just dyed the bottom 4" or so, this insane fushia, it was really really awsome, but it didn't wash out like it was supposed to. After a couple of months, I cut my hair because it wouldn't wash out.
