Did somebody join the Hair Club for Men?

Famously bald Seinfeld star Jason Alexander, 52, showed up to the 27th Annual C.S.A. Artios Awards in Beverly Hills Monday with a full head of hair.

The actor's new look was quite a shock, given that Alexander was practically hairless just three months earlier at the ICON Awards in Beverly Hills.

"I am experimenting with some interesting hair systems," Alexander told his Twitter followers on July 21. "Don't be shocked if you suddenly see pics of me with more hair than usual."
