Any good follicular unit micrografting specialist, who puts large number of densely packed grafts, would charge for the actual number of such grafts transplanted. This is the most time tested and transparent criteria. However, many surgeons try to learn the technique by hit & trial on their patients. For achieving this, they usually charge a lumpsum amount as they themselves are not sure of the number of grafts they would be finally be able to transplant. Having seen a lot of such unfortunate cases, I believe these doctors usually give very few micrografts in front, say one or two rows, followed by now discredited plug/standard grafts behind (inspite of having promised the patient only follicular unit micrografts).
