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 $30, you get a shampoo, haircut, blowout, and Kérastase treatment at Mosaic Salon (up to a $115 value). Choose between their Sahara Avenue and Eastern Avenue locations.

Mosaic Salon's talented stylists whip up masterful hairdos while harnessing ongoing education and products by L'Oreal, Oribe, and Bumble & bumble. Head nests are first treated to a thorough sudsing to free them of dirt, oil, and debris. The shop's pelt-wranglers then cut coiffures into the desired style, leaving patrons sleek enough to talk their way out a speeding ticket from a dolphin. A hair-tamer then applies a Kérastase treatment designed to coax frizzy follicles into a smooth, relaxed state before a culminating blowout locks in styled strands tighter than an affectionate aunt's cheek grip.
