Finger waving
Shaping damp hair with fingers and a comb into flat, rippling S-shaped waves close to the head.
Also: finger waves
Finger waving pushes damp, gelled hair into ridges with the fingers and a comb, making a series of S-shaped waves that lie flat against the head. The waves are left to dry, often under a net or a dryer. Finger waves were the defining short-haired style of the 1920s and 1930s, worn by flappers, film stars and the women of the Harlem Renaissance, and they remain a showpiece for stylists, especially on short relaxed or textured hair.
