If we choose hair from the safest donor area, then we can be more confident that the transplant surgery results will last. This makes it a proficient harvest of the safest area. Now consider FUE’s (follicular unit extraction) harvesting rationale, where the technique only uses partial removal of hair from the donor area. Only 25-35% of the available hairs are harvested, as over-harvesting leads to a variation in the density of the donor area compared to the rest of the hair. In extensively balding areas this becomes a concern but is unlikely to be a problem in small cases.
