Abstract: A method for defining a standardized procedure for a predetermined haircut comprises defining two or more sections of hair on a subject, defining two or more geographic checkpoints on the group consisting of the face, head, neck, and body, wherein each of the geographic checkpoints is generic to a large number of subjects, and defining at least one vector hairway, wherein the at least one vector hairway corresponds to one of the sections of hair and two or more of the geographic checkpoints, further wherein the at least one vector hairway defines a path upon which hair is cut. A code for use in defining a standardized procedure for a predetermined haircut and a method for giving a haircut based upon a standardized procedure are also disclosed.
