Face Shape Guide
Strong angular jaw, equal width throughout
Add Volume Here: Crown
Textured height softens angular lines and draws the eye upward.
Keep It Short Here: Jaw & sides
Extra width at the jaw emphasizes squareness — taper here.
These are starting points — AI try-on shows you the real result on your actual face.
Why It Works
A square face with a prominent jawline can carry the high-contrast undercut look well. The key is managing the proportion between the long top and the side length. A disconnected undercut with a generous amount of length on top creates vertical emphasis that counteracts the strong horizontal line of the jaw. When the top is styled upward or with some volume, the overall silhouette becomes taller and less boxy. A faded undercut with a slightly softer transition is a good middle ground if the full disconnected look feels too dramatic.
How to Style
- 1
Get the sides buzzed to a number 0.5 with a hard part shaved in.
- 2
Leave 4 inches or more on top for styling flexibility.
- 3
Blow-dry forward with a vent brush, then sweep to one side with your fingers.
- 4
Lock in with a medium-shine wax for a structured but not rigid finish.
Angle the top hair slightly forward rather than straight back — it creates diagonal lines that counteract the strong horizontal jawline.
The length of the top section in an undercut drastically changes how a square face reads. AI try-on lets you preview a short-top undercut vs. a long, swept-back version so you can see which proportional balance works for your specific jaw width before committing.
How They Compare
Frequently Asked Questions
Will an undercut make my square jaw look too wide?
Only if the top is kept short and flat. A taller top styled upward or backward balances the jaw's width and prevents a boxy appearance.
Should I choose a disconnected or faded undercut for a square face?
Both can work. A disconnected undercut is bolder and more dramatic; a faded undercut is softer. The choice depends on your personality and style.
What products work best for styling an undercut?
High-hold pomade for a sleek, slicked-back look. Matte clay for a textured, piece-y style. Use a blow-dryer for volume if your hair is fine.
