Superstar Shah Rukh Khan, who has donned a new look in the sequel of his film "Don", says it is a real problem to maintain long hair and wonders how girls manage them so easily.

"It's a real problem maintaining such strings of hairs attached. I haven't shaved for so many days. I have huge respect for women, but really want to ask them how they maintain their long hair," Shah Rukh told the media at the launch of a documentary his production house made on the 1960s epic film "Mughal E Azam" at the JW Marriot Hotel Thursday night.
