It's change you can see: after only 44 days on the job, Obama's hair is already flecked with gray, which appears to wax and wane depending on when his hair was last cut. The presidential barber, Zariff, denied the charges of bloggers who have suggested that Obama dyes his hair gray to appear more distinguished or black to appear younger. "I can tell you that his hair is 100 percent natural," Zariff said. "He wouldn't get it colored." Experts say that whitening hair can be a sign of stress common among presidents, which certainly would make sense in Obama's case. The president may seem as cool as a Bebop club in the middle of winter, but with two wars and a collapsed economy on his hands it's no wonder he's aging fast.
