A line up, also called a shape up or edge up, is a finishing technique where the barber uses a trimmer or razor to cut sharp, straight lines along the hairline: the forehead, temples, sideburns and neckline. Here's what sets it apart, who it suits, how to ask your barber for it and how to style it.

Line up at a glance

  • Top: Any short style
  • Sides and back: Usually paired with a fade or taper
  • Maintenance: High
  • Trim every: 1 to 2 weeks; the lines soften quickly

What makes it different

It gives any short haircut a crisp, defined frame. It's usually added to fades, tapers, waves and buzz cuts, and it can be continued into the beard.

Who it suits

Anyone with a fairly even natural hairline. It's most common with curly and coily hair, where the contrast is strongest. A line up shouldn't push the hairline back; ask for your natural line.

How to ask your barber for a line up

  • Ask for a line up or shape up with your cut.
  • Ask the barber to follow your natural hairline, not move it back.
  • Say whether to line up the beard as well.
  • Bring a photo. Barbers use these names differently, and a picture removes the guesswork.

How to style it

Nothing to style. Between visits, leave it alone or tidy stray hairs carefully with a trimmer.

Variations

  • Line up with a fade: the most common pairing.
  • Line up with a taper: sharp front, soft sides.
  • Beard line up: matching edges on the cheeks and neck.
