Boyish, slicked-back hair was de rigueur at the spring shows, with stylist Guido Palau lopping off locks backstage at Prada and Alexander Wang. On the runways, the look was severe, but this bob has more versatility than you might think. To replicate the look, stylist Cim Mahony added volume by setting the hair in rollers and then back-combing it with a spritz of Less Is More Angelroot Volume Spray and Oribe Thick Dry Finishing Spray. “Hair has been flat and skinny for so long,” Mahony says. “It’s nice to see that volume is finally happening again.” Here, 8 products to get the look at home.
