Hair transplantation has progressed since the introduction of the concept of follicular unit transplantation, a method that recognizes the follicular unit as the basic element of tissue to be transferred. It was aimed to estimate the area of donor scalp with the greatest probability contains the number of follicular units desired to transplant and to analyze the complications in all patients who underwent hair transplantation procedure.


A retrospective study was conducted in our clinic from January 2014 to January 2018.


One thousand thirty hair restoration procedures were performed. Each patient was evaluated for age and gender in addition to the follicular unit density and postoperative complication rates. The mean age was 37.2 years. It was noted that the most common type of hair grouping was the 2-hair follicular unit grafts. The FU density ranged between 70 and 90 and the hair density ranged between 130 and 220 hair/cm2. Postoperative frontal edema was the most common postoperative complication.


Data collected from this series can help to estimate the area of donor scalp with the greates probability of containing the number of follicular units desired to transplant.

Level of Evidence: Level IV, therapeutic study.
