This procedure has been called the logical end point of 30 years of evolution in hair transplantation beginning with traditional larger plugs and culminating in the move to one, two, three, and four hair individual follicular unit hair grafts, which mirror the way hair grows in nature. (Hair Transplant Forum Feb. 1997).

Hair grows in natural groupings of 1, 2, 3 and 4 hairs. These groupings are caller follicular units. The key to follicular unit transplantation is to identify the patient's "natural hair groupings" and use them intact to create from "micro follicular unit hair grafts" that are composed of naturally occurring 1, 2, 3 and 4 hair grafts.
The following picture shows what the follicular unit grafts look like.



Below is a zoomed in picture of the naturally occuring hair groupings in the scalp. As can be seen, the hair are emerging in random groupings(follicular units).



These follicular unit grafts are much smaller than traditional untrimmed micrografts that contain equivalent amounts of hairs.

Their size enables larger numbers of them to be placed in tinier, less traumatic incisions closer together. Using this advanced technique a surgeon can move more hair in a totally natural way - creating a natural look at every stage of hair transplantation.
