Rod Blagojevich’s Chicago-area barber reportedly said the former governor's thick, black hair will likely turn gray while he’s in prison, where dyes are strictly banned.

Blagojevich's barber for more than two decades, Peter Vodovoz told The Associated Press that the 55-year-old ex-governor has dyed his hair for years and that his last dye will fade within three months.

“His hair will turn gray, like (talk show host) Jay Leno's,” Vodovoz told the Associated Press a week after Blagojevich entered a Colorado federal prison.

Blagojevich is serving a 14-year sentence on corruption charges, including trying to sell Barack Obama’s old Senate seat.
