Cut

Disconnected undercut

The defining feature of a disconnected undercut is the abrupt change from very short sides and back to a long top. The contrast is intentional and should remain visible rather than fading gradually.

Top length and direction vary: it can be textured and worn forward, parted and swept sideways, or brushed back. The undercut describes the cut structure, not one required styling finish.

Tommy Shelby's Peaky Blinders look uses closely shaved lower sides and a heavy top shaped forward and to the side. Cillian Murphy has described the show's shaved-sides look; this is a screen-role reference, not a claim that either selected public appearance photo shows the cut.

Estimates describe how closely defining features can be achieved with ordinary cutting and styling while preserving the natural curl pattern, assuming sufficient length. They are not personal suitability scores, promises, or eligibility guidance. Each segment is labeled for screen readers with its subtype and resolved score.

Examples

Textured forward disconnected undercut
Fictional adult model showing closely clipped sides with a clear separation line beneath a longer textured top styled into a short fringe. The model's slight wave is illustrative and does not claim a natural subtype. The sides and back are clipped close beneath a distinct shelf; the top remains substantially longer.

Variations

Choose the details

Classic disconnected undercut

Very short sides and back with a clean shelf line and a longer top left visibly separate.

Textured forward undercut

A longer textured top styled forward into a short, broken fringe above closely clipped sides.

Side-swept undercut

A distinct long top parted or swept to one side over closely cut sides.

Agree on the side length, height of the disconnection, and top direction before cutting; the transition will remain clearly visible.

How close should the sides and back be clipped?
Where should the visible shelf line sit: low, around the temple, or higher?
Should the top fall forward, sweep to one side, or brush back?
How much texture should remain through the top?

“I want a disconnected undercut with short clippered sides, a clear shelf line around the temples, and a longer textured top that I can wear forward into a loose side fringe.”

What changes the result

Bring these variables

The abrupt transition is the key feature; a blended fade is a different finish.
Keep enough top length for the intended direction and texture.
The contrast can be softened by lowering the disconnection or leaving more side length, while retaining a visible weight line.
Hair growth patterns and head shape affect where the shelf line sits; choose its height with a barber.
