Is Zac Efron using his hair as a post-breakup coping mechanism?

Not likely. Although the "High School Musical" star and Vanessa Hudgens, 21, split in mid-December, Efron, 23, is focusing his energy on work -- namely, the Nicholas Sparks movie he just wrapped in New Orleans.

As part of "The Lucky One," Efron had to shave his signature wavy locks into a military-style cropped cut, the Times-Picayune reported.

Efron and Hudgens dated for more than three years before going their separate ways. "It was mutual," a source told "They have been together for so long. It just ran its course."
