The talented actor has been meeting stylists and hair dressers to narrow down on the look he will be sporting in the film.
Shahid has been experimenting and has tried more than 15 looks.
From short hair to keeping it messy to tying a ponytail, they have been experimenting with the look which suits his character.
He has also been trying combinations by coloring his hair, keeping a french beard, etc. He has also been pumping iron at the gym to build muscle.
In addition to this Shahid has been extensively attending workshops for the film. He has been reading the script and in fact also admitted on a social networking site on how this would be one of his toughest roles ever.
