An undercut for an oblong face (men): Works with a tweak

VerdictWorks with a tweak

Verdict: Works with a tweak. An undercut can suit an oblong face if you keep the top flatter and leave some fullness at the sides. You can keep the clear step between the short sides and longer top. The adjustment changes how you wear that longer hair.

An oblong face is clearly longer than it is wide, with fairly straight sides. An undercut adds height on top, which makes an already long outline look longer. Width beside the face helps balance that length.

What to ask your barber

Ask your barber to keep the top flatter and the sides a little fuller. Explain that you want the undercut's distinct step without a tall shape above your forehead.

An undercut uses one short clipper length on the sides, with a clear step up to a longer top. Fuller sides still fit that structure. They don't need to be clipped as close as possible.

Keep length without building height

For an undercut on a long face, focus on where the hair sits. A longer top doesn't have to stand upright. Keep its outline flatter rather than pushing the front high above your forehead.

A fringe shortens the visible face by covering part of the forehead. If you want that effect, discuss leaving enough front length to wear it forward. A messy fringe for an oblong face offers another way to use that shape.

Keep some width beside your cheeks. Cheek-level volume helps an oblong outline, while long, straight lengths beside the face can make it look longer.

Maintain the sides every two to three weeks

Upkeep: sides every two to three weeks. At each visit, ask your barber to preserve the slightly fuller sides as they tidy the cut.

Check the top from the front when you style it. If you've built a high crest, flatten it before deciding the whole haircut doesn't suit you.

Check the shape before choosing a version

The free face-shape finder confirms your face-shape prototype from one selfie; the hairstyle try-on then shows this cut on your own photo.

Compare a flatter undercut with a taller version. Look at the space above your forehead and the width beside your cheeks, rather than judging the haircut's name alone.

Questions people ask

Should men with oblong faces avoid undercuts?
No. Treating a caution as a ban misses the point: nearly every cut works on every shape once something is adjusted. For an oblong-face undercut, keep the top flatter and the sides a little fuller.
Can I keep a long top with an oblong face?
Yes, but length and height have different effects. Wear the top flatter or bring some hair forward as a fringe, rather than styling it upright.
