Disconnection
A cut where two areas of hair are left at very different lengths with no blending between them.
Also: disconnected cut
Disconnection means deliberately not blending two parts of a haircut. The best-known example is the undercut, where long hair on top falls over sides clipped very short, with a sharp step between them. The mullet, short at the front and long at the back, is another. Disconnection gives strong, graphic shapes and can be hidden or shown depending on how the hair is worn. It is the opposite of the smooth blending of a fade.
