The change in Saif's hair length has been cleverly incorporated in Love Aaj Kal.

A unit member told, "The entire San Fransisco schedule was designed on the basis of Saif's hair and beard. Saif had to have four different looks so schedule was timed in such way that Saif could play with the length of his natural hair rather than use fake beard and hair extensions."

The scene where Saif is actually getting a haircut at the salon is real one. "The stylist was giving Saif a haircut in reality. Imtiaz Ali took it as a shot in the film," said the source.
