Washington, Jan 10 : Mel Gibson is flaunting a bald head these days - and the reason behind his `no-hair scalp' is a dare!

The actor's son had dared him to shave off his head, and the actor obliged.

While the `What Women Want' actor was sure he'd look good with a baldhead, the daring antic wasn't really appreciated.

Thus, the embarrassed actor is again growing back his hair.

"I thought it would be cool. That I''d be Shaft," Contactmusic quoted him as telling the New York Post.

He added: "Looking like I was a plucked chicken, the only perk was I wasn''t recognised in a crowd." (ANI)
