What does the term "undercut" mean?

The term "undercut" refers to a hairstyle where the hair on the top is left longer while the sides and back are clipped very short. This style creates a distinct contrast between the longer hair on the top and the much shorter hair underneath, allowing for versatile styling options on top. The undercut is popular because it can be combined with various hair lengths and textures on the top, enabling creative styles that can be slicked back, left tousled, or styled in different ways for a modern look. The emphasis on keeping the top long while shortening the sides is what characterizes this hairstyle, making the definition accurate.
