Nathan Rosenkranz can spot a trend coming from a mile away. It’s a skill he’s honed after years of living in New York City and working with everyone from athletes to celebrities. So is the mullet really making a comeback? For the uninitiated, the mullet was described as “business in the front and a party in the back” when it first reared its head in the 1970s, and it’s come in and out of fashion ever since. Stylist at Hair & Co. in Brooklyn, Rosenkranz has had a lot of requests from his female clients recently for something he calls a modern version of the shag-mullet combination. “Think of it as a shag without the volume,” he says, “with the shorter texture on top collapsing into longer hair in the back.” Rosenkranz calls the look, which is a bit shaggy, a fashion mullet.
