Hot rollers have it kinda rough — they’re most often associated with cranky old ladies and pageant queens. But the truth is that they’re actually a really simple, natural way to add sultry volume and lush waves to your mane. We saw so many models rocking rollers backstage at Fashion Week this fall, that we just had to give the retro stylers a try for ourselves. We enlisted Kelsy Osterman, a stylist at NYC’s Cutler Salon, to help demystify the old-school tool. Follow the video tutorial and learn how to create glam ‘70s waves that will transform you into a stone cold fox — in 20 minutes flat.
