They don't last long, the days, or are you confessing to being a serial killer?I think vampires can change their hair, though I think it depends on which tv/movie universe you are following.
Who besides a teenager would dye their hair green?
Oh wait. Katy Perry.
I'm fairly certain that I'm not being hunted down by a creature of the night but I will continue to perform this frequent ritual of hair removal. Not because it's necessary but rather I'd feel like a man if I didn't.
Although, there are some days when I wouldn't mind being a man but they don't last long.
