The film, originally released in South Korea in 2005, tells the tale of Su-hyeon, a woman suffering from leukemia, whose sister and roommate Ji-hyeon gives her a wig to cover the baldness which results from her chemotherapy. But little do either of them know that the wig was actually made from the hair of a suicide victim (gasp!), and thus Su-hyeon begins to take on the characteristics of the hair's original owner (which, needless to say, are not pleasant ones.)
Right off the bat, we've got an inescapably silly premise, and director Shin-yeon Won takes it all way too seriously. While interestingly shot, the pace is discouragingly slow for the most part, and the structure is such that at times the plot can be pretty tough to follow. Then, once you actually figure things out, it all turns out to be so cliche you almost wishe you still didn't know what the heck was going on.
The film's only memorable performance is given by Seon Yu as Ji-hyeon, the perpetually anguished and put-upon sister of the possessed wig-wearing cancer victim. Of course, she puts in her solid performance in spite the maddeningly inexplicable decision of screenwriter Hyun-jung Do to make her character completely mute as a result of a car accident which is vaguely connected to the wig, but never fully explained.

The big revelation near the end manages to be confusing, ludicrous and boring all at the same time. And the final scenes, meant to be both shocking and poignant, are just clumsy.
Director Shin-yeon Won may be a talented stylist, and "one to watch", as some critics have branded him--but his debut The Wig is definitely not a picture that does his nascent skills any justice. He's made two more horror/thrillers since, which are allegedly far better, so he may become a major player in Asian horror despite this lackluster first effort.
