Ilayathalapathy Vijay does not change his getup easily. In most of his movies he comes with a normal hairstyle. His normal hairstyle is liked by all. Some time he used wigs in songs or certain scenes like in puli. But in Bairavaa he has used wig throughout the movie.
When this was asked to the cinematographer of Bairavaa Mr.Sukumar, he said when Bairavaa pre production was going on Vijay was acting in Theri and Vijay had a almost bald look in the climax of Theri . When Bairavaa started Vijay still had that bald look so the movie team decied to use a wig so it will give some stylish look for Vijay in fight scenes in the movie.
