Over-direction
Combing hair away from its natural fall before cutting, so it ends up longer in one direction.
Also: overdirection
Over-direction means combing a section away from where it would naturally fall, towards a guide, before cutting it. When released, that hair is longer, because it had further to travel. Stylists use it to keep length at the front of a bob, to make face-framing layers grow longer towards the back, or to build weight on one side of an asymmetric cut. Together with elevation it decides the shape of almost every cut.
