Biting your fingernails is a bad habit that nail technicians help to prevent by shaping nails into brussels sprouts. Flaunt artistically crafted nails with today's Groupon: for $15, you get a Shellac manicure at Imana Sky Salon in San Marcos (a $30 value).

Imana Sky Salon's aestheticians cultivate elegance while plunging beauty-buffing clients into black-and-white décor beneath a crystalline chandelier. During the 20-minute Shellac manicure, digit tips bask in lavish attention as a nail tech fastidiously grants them an elegant shape and cleans up unruly cuticles like a sheriff's finger puppet. As hands unwind under the primping regimen, gazes meander to Couture prints above the nail table and a gossamer abstract piece, reminiscent of swirling peacock feathers, along an adjacent ebony wall. Chip-resistant Shellac polish lacquered onto nails weathers stresses in the outside world, standing strong against fierce finger drumming and high-fives from rugged iguanas.
