Asymmetry
A haircut that is deliberately longer or shaped differently on one side than the other.
Also: asymmetric cut
An asymmetric cut is different on each side: one side may be cropped short while the other falls to the jaw, or a fringe may sweep steeply across the face. It is made with over-direction, a side guide and often disconnection. Asymmetry became fashionable with the geometric cuts of the 1960s, the new wave styles of the 1980s and the side-shaved looks of the 2010s. A deep side parting gives a softer, grown-out version.
