6. Ocean waves
This adorable hairstyle from 1920s was favored by the black men. It was created by using a special hairbrush with a little hair gel and also some sprays. While this style may look pretty ordinary now, 90 years ago it was a real hit hairstyle. In this hairstyle the hair was cut real short (about 4 mm (0,15 inches) and the hair was styled with a hairbrush to create waves.
