okay, if you have black hair, manic panic won't work on it. if you leave it on overnight, it'll give a slight tint that's only noticible in the sunlight, but it'll still be black. like if you put blue on it, in the sunlight it'll look blue-black. it won't look like an unnatural color.
i suggest you bleach first.
