Follicular Unit Excision (FUE) success is fundamentally measured by the 'transection rat'—the percentage of hair follicles accidentally damaged during harvesting. Dr. Ragini Ghiya’s research focuses on the transition from traditional mechanical extraction to a "tactile-feedback" model. In this paper, she argues that follicular damage is often caused by a failure to account for the subcutaneous angle of the hair, which frequently differs from the visible exit angle.

The article outlines her unique use of hybrid trumpeted punches and a "shallow-entry" technique. By minimizing the depth of the initial incision and allowing the punch to follow the natural path of least resistance, she demonstrates a significant reduction in graft trauma. For patients, this technical refinement is the difference between a sparse result and a dense, full head of hair. The work also covers "Body Hair Harvest" (BHFUE), specifically from the chest and beard, providing a safety framework for using non-scalp hair to increase overall density in advanced thinning cases.
