Tell us about hair restoration and follicular unit extraction.

The hair grows in the scalp. We can think of it as "follicular units." So follicular units basically involve anywhere from 1 to 4 hairs. And the traditional method of harvesting was actually harvesting large areas of multiple follicular units at one time. Now what we're able to do with the system we have in place, the NeoGraft system, is actually a micro follicular unit extraction. So, much like the endoscopic techniques that really revolutionized orthopedic surgery, neurosurgery, and general surgery, it now has application in plastic surgery. It's really disruptive technology in the sense that we're now able to harvest individual follicular units, and that's great from several perspectives. One is that there's that little disruption and trauma to that delicate follicular unit, which is of course what grows a patient's hair. Secondly, there's minimal disruption to surrounding follicular units that we're going to leave in place and that are going to continue to grow in that area, and possibly harvest later on if we want to go back and give a patient more density. Everything now is going towards follicular unit extraction, or FUE, as the best way to both harvest and transplant hair in hair transplantation surgery.
