Slick back is a commonly found hairstyle amongst men that involves combing the hair back smoothly, using wax or gel. While the term slick back is widely used, there are several other synonyms that can be used to describe this style. Some of these synonyms include "pompadour," which is a more stylized version of the slick back that involves adding volume to the front of the hair, the "undercut," which involves keeping the sides and back of the hair short while slicking the top back, and "wet look," which involves using a wet-look gel or pomade to get a shiny finish when styling the hair. These are just a few examples of words that can be used to describe the slick back hairstyle.
