Classic Undercut
Shaved sides with a much longer top for high contrast.

A men's cut with tapered sides and a back hairline shaped into a smooth U, with medium length on top styled back for a clean, sculpted outline.Our advanced AI generator lets you try out the U-Shape Cut look instantly. See if it is the right choice for you before making a commitment at the salon.
This cut is particularly flattering for individuals with oval, heart, or square face shapes as the rounded nape helps to visually elongate and soften the neck area. It works best on straight or wavy hair with medium density, providing enough body to hold the swept-back top while keeping the tapered edges crisp. It appeals to those wanting a professional yet distinct look that requires only a moderate amount of daily styling effort to maintain its sculpted silhouette.
Request a low to mid-taper on the sides and back, emphasizing that you want the back hairline finished in a smooth, rounded U-shape rather than a square or V-cut. The top should be cut to a medium length of three to four inches and lightly textured with point-cutting to allow for a clean, swept-back finish. Specify that you want the transition between the tapered perimeter and the longer crown to be softly blended for a seamless, cohesive appearance.
To keep the U-shaped perimeter looking sharp and the tapers clean, you should schedule a touch-up every three to five weeks. For daily styling, use a small amount of medium-hold pomade or clay on damp hair, then use a comb or brush to direct the hair back and set the sculpted shape in place.
Unlike a square neckline which features sharp right angles, the U-shape is softly curved to follow the natural contour of the neck. This creates a more organic look that tends to grow out more naturally without looking messy or blocky between salon visits.
This cut is most effective on straight to wavy textures where the direction of the hair can be easily controlled with minimal product. Extremely tight coils may obscure the subtle U-curve at the nape, though a skilled stylist can adjust the taper depth to compensate for the curl pattern.
While the U-shape is traditionally paired with a swept-back style to highlight the clean neckline, the top can also be worn in a side part or slightly forward. However, keeping the length directed away from the face best showcases the sculpted taper and the unique rounded shape of the back.
