A cheap party store wig? I have never dyed my hair black, so I don't know the answer to your question. Please post photos -- Snape is one of my faves! :D
Oh yes, stick to a wig. My daughter who is very blonde tried the 'koolaid temporary'colour when she was a teenager and ended up with lovely pinkish blonde hair until it grew out.
Looking at your sig pic ( Guess that is you Amanda) your hair isn't that dark, and you could get away with using a color rinse. It washes out within a week, and usually sooner then that...You could go to a salon.. it would probably be about $12.. at least no more then that.. Hope you have a good time at the movie..
