Exte (エクステ, Ekusute) is a 2007 Japanese supernatural horror film written and directed by Sion Sono, and stars Chiaki Kuriyama, Ren Osugi, and Megumi Satō. The title is a Japanese slang shortening Romanization of the English term "extension" from "hair extension".

The plot involves an aspiring hair dresser (Kuriyama) who becomes the infatuation of a tricophilic man who sells hair extensions to nearby hair salons. The source of the hair is the stolen corpse of a girl whose dead body continues to grow beautiful and voluminous black hair that comes alive, driving those who use the extensions insane or killing them. The movie was released in the U.S. as Exte: Hair Extensions.
