Who Should Get an Undercut?
An undercut has a hard, visible line at about ear height between a long top and very short or skin-shaved sides, with no blending; a taper fade, by contrast, blends gradually. The disconnect can be subtle, such as a #2 or #3 on the sides with three inches on top, or dramatic, with skin on the sides and five or more inches on top. The top usually runs three to six inches or more and can be slicked back, quiffed, worn curly or tied in a bun, so the cut suits men who want strong contrast and plenty of styling options. It works on straight, wavy, curly and coily hair; round faces suit a pompadour or quiff undercut, and oval faces almost any version. Ask for your top length and texture, your side detail, such as a #0 or a high fade, and a sharp disconnected line with no blend. Trim the sides every two to three weeks; the contrast fades after four to six.
The undercut is one of many cuts in the short sides long top family, which also includes faded and tapered versions.
If you want the sides taken all the way to skin rather than a guard, our guide to shaved sides haircuts covers razor, buzzed and one-side versions.

The undercut is the base of many hipster haircuts, where it is worn with a longer slicked top and a full beard.
If you want the step between the sides and top to show on purpose, see our disconnected undercut guide with 30 styles and the words to use with your barber.
Curly and coily hair has its own set of undercut options; see the curly undercut guide for guard numbers, curl care and 48 styles.
It is more forgiving than its reputation suggests, because the disconnect can be as subtle as you like. Your barber cuts above the line with scissors and clips below it, so check that the line sits level on both sides before you leave.

How to Cut the Perfect Undercut (Barber Instructions)

Prep
Dampen hair or cut dry for precision. Section top hair away from the sides before starting.

Sides & Back
Use clippers (#0–#2) or skin fade for very short or shaved sides and back. Decide disconnected line height.

Top Length
Leave 3–6+ inches on top, keeping bulk for styling options.

Disconnection
Create a sharp, clean line between the top and sides, no gradual blend. This is what makes an undercut an undercut.

Clean neckline, sideburns, and around ears. Style dry to show the client the final contrast look.
