Summer may be (sadly) over, but that doesn’t mean you have to stop wearing your hair in tousled waves. Celebrity hairstylist—and THE master of lived-in hair—Anh Co Tran recently dropped by the Women’s Health offices to show us how to get gloriously undone waves that are perfect for any season. (Demi Lovato, seen above rocking this look, is one of his regular clients.)

The best part: This style thrives on imperfections, so you don’t have to have the golden touch to do it yourself.
