Having frizzy, unkempt hair can make you appear disoriented and unhinged during job interviews, first dates, and shouting matches with the neighbor's bush. Keep it together with today's Groupon: for $99, you get a keratin hair treatment at Studio 157 in Hendersonville (a $350 value).

At Studio 157, talented beauty mavens combat the ravages of dry winters and harsh hair chemicals with nourishing, formaldehyde-free keratin hair treatments. Consultations kick off all services, granting patrons a chance to divulge their hair's needs and secret crushes on the heads of '80s keytar players to attentive stylists. Hair gurus then set to work filling in dry, cracked cuticles with keratin, a naturally occurring protein that strengthens and protects fragile locks. The protein saturates hair follicles, rendering coifs as smooth and slick as a slip 'n' slide that can speak French. While manes bask beneath the one-hour treatment, eyes feast on the salon's lustrous hardwood floors illuminated by picture windows and brass chandeliers.
