For a horror comedy about killer hair extensions, this movie takes itself surprisingly seriously. I'm... not saying it's bad, but... I was expecting more time laughing and less time squirming at fairly legit attempts at body horror. There are some genuinely amusing humor bits scattered through the movie, but they're mostly squished to the beginning and end of the film to make room for the horror, as the hairstylist protagonist protects her niece from child abuse and watches her salon coworkers get picked off one by one by a vengeful ghost's ever-growing hair. Score: 2 stars out of 4, but add a star if you like Japanese horror films.
