Every time a new idea crosses the mind, a new hair sprouts as the idea tries to escape the brain and patent itself. Keep thoughts in check with today's hair-disciplining Groupon: for $25, you get three men's haircuts at Y-Chrome (a $63 value).

Y-Chrome's head gardeners manicure dapper 'dos from overgrown hair jungles. Beckoned inside by the shop's all-glass façade and checkered tiles, cut-needing clients lean back and relax in the barber's chair, while experienced hairsmiths fashion their cranial pelts. Customize your look by buffing back your bangs, tapering your nape, adding layering, shaving it all off for a scorched-earth look, or buzzing in your grocery list with the detail trimmer. Clients can schedule an appointment, but drop-ins are always welcome; pool tables, men's magazines, and a flat-screen TV that hugs the exposed brick wall entertain waiting customers. After your cut, feel free to hop into another chair for a shoeshine ($5 for shoes; $7 for boots), or sip a microbrew while you toss darts at a picture of your old haircut.
