A do-rag or du-rag is a scarf worn on the head after a hair treatment process. Think hair doo.
Do-rags were originally founded as the headgear of poor African American women laborers and slaves in the 19th century. In the 1930s, during the Harlem Renaissance and Great Depression, the do-rag evolved into a hairstyle preserver. After the Black Power Movement in the late 1960s, the do-rag became a fashion statement among African Americans, worn by rappers, athletes and men of all ages. In the 2000s, wearing do-rags in public lost popularity in certain areas but maintained its popularity in others.
Also: It was worn in a cap-like manner and was also known as a do-rag, durag, or dew-rag. In 1990s and 2000s, do-rags re-emerged as wave caps. Wave caps were popularized by several rappers as a fashion accessory. However, the main purposeof a wave cap is to accentuate waves in the hair.
