The logic of follicular unit transplantation

Follicular unit transplantation is a method of hair restoration surgery whe re hair is transplanted exclusively in its naturally occurring, individual follicular units. The evolution and rational for follicular unit transplant ation will be discussed, as well as the logic for the various techniques us ed in its implementation. Specifically, the logic for single strip harvesti ng, stereo-microscopic dissection, automated graft insertion, and large tra nsplant sessions will be reviewed. The central role of the follicular unit constant in the surgical planning will also be discussed.
