Undercut SimulatorLong on top, clipped underneath, and a hard line between the two.

An undercut is a haircut where the sides and back are clipped very short, usually with a #1 or #2 guard or down to the skin, while the top stays long, 3 inches or more, with no blending between the two. That sharp, disconnected line is what separates an undercut from a fade.

The long top is what makes it versatile: slicked back, swept to the side, pushed up into a quiff or left wavy and loose. Women's undercuts work differently, as a shaved patch at the nape or above one ear that stays hidden under longer hair.

This undercut simulator clips the sides on your photo and keeps your face, hairline and ears as they are. Compare it with the wavy undercut and a fade in the gallery to decide how much contrast you want.

Who an undercut suits

  • Thick, straight or wavy hair

    Removing bulk from the sides is the point of the cut. Thick hair that puffs out above the ears sits flat and controlled once the sides are clipped.

  • Oval, square and round faces

    Short sides with height on top slim a round face and sharpen a square one. On a long face, wear the top swept to the side rather than tall.

  • Fine or thinning hair: careful

    Clipped sides make a thin top look sparser by contrast. A textured crop or a low taper is usually kinder to thin hair.

  • Plan for the grow-out

    The sides need 3 to 4 months to reach the length of a normal short back and sides. Wearing the top down over them, like a two-block, hides the awkward stage.

Keeping an undercut clean

  • Sides every 2 to 3 weeks

    The disconnection only looks deliberate while the sides are tight. Many people re-clip them at home between barber visits.

  • Daily product on top

    Pomade for a slick back, matte paste or clay for a messy quiff, sea salt spray for waves. Expect three to five minutes each morning.

  • Cost: about $30 to $50

    Standard US barbershop pricing. Home clippers make the side touch-ups nearly free.
