How to get hair dye out of skin? ASAP!?

I dyed my hair black yesterday, and my forehead is now all black aswell. Me and my boyfriend are going out to dinner in a few hours with our famalies and im worried i wont be able to go as its still not out. My boyfriend has tried rubbing bleech on my head, nail varnish remover and oven cleaner as these were suggested on various websites. He was also advised to try petrol or diesel so he has just gone out to get some, is there anything else we could try, i really cant miss this meal!
