No amount of absurdity—and this film delivers plenty—can clip the essential enjoyments of Sion Sono’s hair-horror flick, about haunted extensions that strangle their style-obsessed victims to death. Sono is still best known for 2002’s grim Suicide Club, but here he takes a likeable turn toward mainstream, almost feminist thrills à la Ginger Snaps, as hairdresser-trainee Yuko (Kill Bill’s stoic Kuriyama) must do battle with the sadistic, woman-hating morgue attendant (Osugi) who commands the killer tendrils. Scary? Hardly. But the film has luxurious height and volume to spare.
