Today's theme?
Evil hair.
I'd like to talk about exactly why hair is such a staple in Japanese horror movies, stories, games, everything  really, and to be honest, it deserves its own entry to shine as the paradigms of great traditional horror that it is.  Let's take a look on why the subject of  "hair" is so important in Japanese folklore, culture and horror, as well  as some excellent usage of it in modern-day media.
You read that right, I'm going to be talking about really good, actually scary traditional Japanese horror!
Hair  is one of the most basic and recognizable elements of traditional  Japanese horror. But the reason that a woman's long black hair has  become so ingrained into folktales and scary stories that it has become  frightening on its own dates back a long, long time, so that we must  understand how it came to be before we figure out why.
