Kangana, please don't shave off your beautiful curls! Your hair is your crowning glory and your USP. Nobody else has in the industry has your kinda hair. It's really not worth it just for some film (which will probably flop). You also need to work in other movies, so think about continuity and don't ruin your beauty. Ask Madhur if you can wear a wig or something, but don't let him shave it off girl...or you'll regret it!!!
