The FUE technique consists in taking, using a punch (0.8 to 0.9 mm), from the occipital and temporal donor area, follicular units in order to transplant them directly into the bald region to be treated. . Although the quality of the follicular harvest is directly operator dependent, improvements in instrumentation have made it possible to increase the speed of hair transplant harvesting and significantly reduce the loss of follicular units.
When looking at a healthy scalp using magnifying glasses, the hair is seen to emerge through the skin in clumps ranging from 1 to 4 hairs.
The removal of a follicular unit is carried out using a micro-punch. This instrument allows by its sharp and circular edge, to isolate a follicular unit from all its cutaneous and fatty attachments. Once isolated, the follicular unit is recovered using a micro-forceps before being reimplanted on the bald area. The follicular units are stored on an enriched medium before being transplanted. Hair transplants are sorted and grouped according to the number of hair follicles per follicular unit.
