I'm planning to cosplay as Spike from Cowboy Bebop for a con coming up, and I can't afford a wig (and I hate wearing wigs anyway), so are there any temporary hair dyes that I could use that would last a day and could be washed out with shampoo? I've got mediu brownish hair (there are pics in the Show Yourself thread) and would need to dye it dark green.
Nothing that'll only last a day, but there are some spray ons which you usually get from costume shops. They'll come out in 3-4 days.
I bought some green hair gel from Sally's for halloween. I've got black hair so I had to use the whole bottle, but it worked. It did make my hair hard as a rock though. I believe is said "Snookie" on it but I don't know if its referring to "That Snookie"
Some kinds of manic Panic will wash out in a couple days, I think, but if you want it to look good, you'll have to go with a permanent dye. It'll grow out...
