Floyd's 99

If Rolling Stone ever opened a barbershop it would look like Floyd's 99. Katy Perry uses one as the backdrop for a scene in her Hot n’ Cold video; HBO Entourage stars appear in front of another; and several reality TV shows have filmed their contestants getting rock star makeovers there. The brainchild of the O’Brien brothers, the first shop opened in Denver in 2001 and has since become the fastest growing group of barbershops in the United States with 40 locations in 9 states. Trained stylists and barbers provide services that rival high-end salons at low end prices.
