ARTAS is a robotic-assisted device. This means that the ARTAS machine digitally maps the donor area and harvests donor hair so that the area retains its original appearance. In addition, it uses a blunt dissection technique that minimizes injury to the grafts, which improves the likelihood of a successful transplant.
However, NeoGraft is a hand-held system. It uses the sharp punch method of extraction. Since it is not robot-operated, success depends on the skill and technique of the user.
