Okay, so I made the mistake of impulsively self-colouring my hair on Monday afternoon.
Back story:
I had my hair bleached in early December (2010) from a dark blond to basically peroxide.
Then in February-ish I had it coloured a dark red/brown which faded to blond again (through the bleach). Then a few days ago I dyed it blue-black, for reasons not known to me.
Fact of the matter is I look like a moron and need to solve this problem. I am getting my hair cut in a few days, so that will help solve the matter dramatically but how long should I wait and even if I can bleach it after this? HELP.
