Hack: Sleep with your hair wrapped up overnight to wake up with a natural wave.
DIY it: This works best when you apply a bit of mousse to damp hair at the root. Brush half of the hair up into a ponytail. Then, use a moldable, soft tool, such as the Wrap Up, to secure your hair on top of your head. Open it up, pull the hair through, pinch it closed, roll it up, and bend it into a loose bun. Twist the remaining bottom half of the hair into a low ponytail bun. Get some beauty rest!
When your hair is released in the morning, it will have a loose wave in it from holding that bun shape. You can then spend just five minutes touching it up with a curling iron, like the Beachwaver S1.25. This will "polish the waves and get that tousled Victoria’s Secret look," Potempa said.
