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 $30, you get a women's haircut and blow-dry at Andrew John Salon in Mt. Lebanon.

Husband-wife duo Andrew and Tracey Valko harness more than 30 years in the hair industry and experience examining international 'dos in Paris, London, and New York to pamper local locks with custom styles and organic products. After designing a clip to suit a client's style and schedule, tress-smiths frame chins and cheekbones with edgy angles or beachy waves, lightening head loads to make room for whimsical beanies or delicately balanced water jugs. Before releasing their customers back into the wild, stylists strategically aim blow-dryers at each head, boosting volume for hair-flips, emphatic nods, and impressive 360-degree rotations.
