Shah Rukh Khan seems to be in a mood to experiment with his hair these days. In September, the superstar was spotted at the airport with streaks in his hair. And seems he liked adding a dash of colour to his hair. On Thursday night, SRK attended the launch of a jewellery store, but this time he sported a steak of bright blonde colour. It was in Don that the actor opted to tie his hair in a pony and soon many actors followed suit, let’s see if this colourful streak has his colleagues knocking on their hairstylist’s door now.
