Eyebrows are the face's primary mode of emotional expression and if left unkempt can grow shaggy, droop toward the center, and convey a perpetual desire to wrestle. Express yourself accurately with today's Groupon: for $7, you get an eyebrow-threading session at Brow Threading (a $15 value).

The follicular technicians at Brow Threading whisk away facial hair with a removal procedure that's more precise than waxing, plucking, or facial-hair immolation. During the five-minute treatment, one of Brow Threading's hair-removal heroes employs intertwined pieces of thread, which trap follicles and pull them out in the same direction by the root. Hair removal lasts up to four weeks, demolishing unwanted soul patches or sculpting eyebrows into a permanent state of surprise.
