First made popular by Janet Jackson and Jody Watley in the '80s, the big, bodacious, body wave is officially back! The great thing about this sexy style? Soft, rippling waves flatter all hair lengths from short, Rihanna-esque crops to long locks, a la Joy Bryant. And the look is super-easy to create at home: Simply separate hair into sections (small if you want tight waves, bigger if you want a looser texture), and then wrap around the barrel of a one inch curling iron, keeping the barrel closed.
