You could call Hairroin "edgy," but that wouldn't do it justice, considering that after you get your cut they'll give you favors like car air fresheners featuring skeletons in pretty updos, or pens that look exactly like syringes. (Seriously. Folks do a double take when we pull ours out at the grocery store.) But even with a heavily pierced, tatted-up staff — and a chic owner who almost won Shear Genius (you know, that Bravo show) — Hairroin doesn't feel too cool for school. In fact, it'll work for little ol' unhip you. Trust us, you'll feel right at home sipping Champagne and chatting with your sweetly smiling stylist who — check her bio — recently sexed up the manes of reality-show women trying out for the Pussycat Dolls. The best part is that once your do's been done, you'll be filled with confidence, so much so that you might even strut right into one of the many tattoo parlors that dot the area. 1553 N.
