Besides providing a particularly compelling reason to stay apprised of world events, our collective crush on Anderson Cooper has succeeded in reinforcing one other important value: gray hair can be hot. Yeah, no one likes to get old, but men spotting wisps of silver on their heads can take comfort in knowing that they lend a certain air of distinction when coiffed properly. We trust Barbershop Lounge (254 Newbury Street, Boston, 617.450.0020) for men's color services ($45); the stylists at this swank gentlemen's club can definitely take those grays away, but they also offer a "blend" option that lets you keep just a bit to achieve that salt-and-pepper chic.
