Aside from wearing boldly lettered sandwich boards, the human body communicates most clearly and efficiently through its feelers and its eyebrows. Today's Groupon gives eyebrows the customization they seek: for $10, you get two eyebrow-threading sessions at Changes Hair, Skin, Nails & Spa (a $20 value).

A full-service salon and spa, Changes’ skilled aestheticians perform feats of beauty enhancement through a slew of pampering services, including everything from body treatments to eyebrow threading. Patrons can stop by the spa’s 4,000-square-foot relaxation wellspring to add some definition to their brows with a 15-minute eyebrow-threading session. In the steady hands of a certified threadster, a strand of thread is deftly weaved around each individual filament, systematically ousting one hair at a time for precise, personalized shaping. Because there are no chemicals involved, this simple process is all-natural, occurring with minimal discomfort and generally with much less irritation than waxing or tying eyebrows to the doorknob and slamming it shut. Clients can expect their sharp look not to dull for three to four weeks before returning for their second session. Threading may also be employed to raise the eyebrow’s arches.
