Nomenclature Proposal for the Zones and Landmarks of the Balding Scalp

In 2001, Michael L. Beehner presented a standardized nomenclature for the balding scalp, dividing it into three major areas: the frontal region, the midscalp, and the vertex, with additional subregions and landmarks. The proposal introduced the "vertex transition point" and defined subzones like the frontal hairline zone, lateral "crease" zones, and posterior parietal triangle zones, which are crucial for hair restoration surgery. It also provided precise definitions for common scalp landmarks to ensure clear communication among professionals in hair-related fields. The system incorporated feedback from hair surgeons and was shared with the international hair transplant community for further input.
