What does the term "undercut" refer to in barbering styles?

The term "undercut" in barbering refers specifically to a style where the sides and back of the hair are clipped very short, while the hair on the top is left longer. This creates a distinct contrast between the longer hair on top and the shorter hair underneath, emphasizing the length and style of the top section. The undercut offers versatility, allowing for various styling options for the longer hair above, such as slicking it back, sweeping it to the side, or leaving it tousled. This technique is particularly popular in modern men’s hairstyles and can complement a variety of looks, from edgy to traditional.

In contrast, a hairstyle where the hair is all the same length does not create the same visual separation that defines an undercut. Long sideburns are a different aspect of hairstyling and do not directly relate to the concept of an undercut. Similarly, a hairstyle with bangs only does not feature the same length variation between the hair on top and the hair on the sides and back, which is a defining characteristic of the undercut style.
