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 $125, you get a Brazilian blowout at Salon Karma (a $300 value).

Salon Karma's trio of stylists provides chic sleeking services in a relaxed and welcoming atmosphere. The 90-minute Brazilian blowout treatment deftly smoothes strands, improving hair’s condition as it banishes frizz, curls, and atonal accordion pleats. One of Salon Karma's stylists will shampoo your hair with a preparatory solution, then coat strands with the formaldehyde-free formula, which busily sets out to flatten cuticles into silken submission.

Next, tresses are blown dry and flat-ironed before being rinsed and bathed in a solution-sealing mask. Routine-loving manes are rinsed again, and then a smoothing serum is applied and strands are given one last blow-dry to leave hair straighter than delegates to the right-angle convention. The treatment is effective on any hair type, and glossily smooth results last up to 12 weeks.
