Hair transplant surgeons place a high importance on the integrity of naturally occurring hair follicle units to find improved methods of hair graft harvesting, dissection, grading and transplantation. Studies have concluded that there is a measured increase in the yield of follicular unit grafts and the total amount of hair harvested from the donor strips when technicians use dissecting microscopes as compared to magnifying loupes with trans-illumination.
