Waves are a hairstyle for curly hair in which the curls are brushed and/or combed and flattened out, creating a ripple-like pattern.
The hairstyle is achieved with a short-cropped haircut on top and frequent brushing and/or combing of the curls (which trains the curls to flatten out), as well as wearing a du-rag. Wave pomades and moisturizers can help hold the hair in place while preventing the hair from getting too dry. A durag is worn to preserve moisture while compressing the hair and holding it in place to create the desired waves.
In the early 21st century, as many African-American men sought to style their hair with texture-altering products, "pomade hair moisturizer" waves became a popular hairstyle. Men produced waves by washing their hair then putting on their do-rags right after putting on their choice of moisturizer.
