Aside from warming our brains and framing our faces, hair provides the only concrete evidence of the existence of wind. Treat breeze detectors right with today’s Groupon: for $9, you get a shampoo and haircut at Great Clips (a $18 value). This Groupon is valid at either the Brookfield location on Capitol Drive or the Menomonee Falls location on Silver Spring Drive.

Great Clips harnesses the vast resources of a national salon chain to provide personalized, professional styling services to follicle frolickers. Highly trained hair tamers tame wild wigs and also serve as style guides through the often-intimidating tonsorial jungle, answering clients' questions about hair trends and maintenance. The stylish snipping ($13) gets started after a warm shampoo and rinse ($5) cleans scalps and washes away the melodies of musical comedies stuck in hair. Walk-ins are welcome.
