Why use a comb to style your hair when you can simply wear a hat? Alva K. Dawson patented this “combined head covering and hair comb” in 1920—a solution for keeping your hairstyle perfect while “riding a bicycle, playing golf, or driving.” The flat hat not only protected the wearer’s head: whenever you took it off, its integrated comb would pass through your hair, magically “move it into the proper and orderly position.” In 2020, your hair would never be messy again!
