TLDR A new training model using an orange helps surgeons practice parietal whorl hair transplants effectively.

The study introduced a novel training model for designing and performing parietal whorl hair transplantation, addressing the growing demand for skilled surgeons in this area. The model involved using an orange to simulate the scalp, with outward divergent arc curves drawn from the navel to guide the creation of recipient sites using 23G needles or 1.0-mm blades. Hair shafts were then transplanted at varying densities, with 30 follicular units (FU)/cm² achieving a good appearance, while 40-50 FU/cm² provided better results. This model offered a practical training method for new surgeons and a rehearsal opportunity for experienced doctors, effectively aligning with the natural lines and direction of the parietal whorl.
