Myth. According to Greek mythology. Natural redheads have always had a tough time throughout history just for being ginger, that was until Ron Weasley made it cool. The colour red is synonymous of the Devil and evil in general, so redheads were accused of being friendly with Satan. Although you weren't able to stop people from turning into vampires when they died, there were a few techniques that you could try in order to stop them from rising from their graves. You had to cover their graves with stones or rocks, put coins or soil in their mouths and coins over their eyes. Maybe sprinkle some holy water over their graves, just to be extra safe.
