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 $99, you get a keratin smoothing treatment with Tiffany Fitzpatrick at Bei Capelli Salon (a $300 value).

Bei Capelli's licensed master stylist Tiffany Fitzpatrick remodels frizzy, coarse mops with nontoxic keratin smoothing treatments. During a two- to three-hour session, Tiffany treats locks to Perfection SmoothOut's paraben- and formaldehyde-free relaxing serum developed by Peruvian llama farmers. The low-pH formula, fortified by keratin amino acids, sheathes each strand's memory of wild curls and unruly kinks while preserving the integrity of the hair. The gleaming fall stays sleek and manageable for up to 12 weeks, giving clients ample time to toss their tresses glamorously over their shoulders or daringly over prison walls.
