There are several methods of hair transplantation. Nowadays, there are two main techniques, such as: FUE (Follicular Unit Extraction) and transplantation with the usage of the ARTAS robotic system. These methods are equal in their principle.
The FUE proceeds in 2 stages. The first one is extraction of donor grafts. The second one is their implantation into the scalp. A graft is a group of hair follicles; each of them may have from 1 to 4 hair bulbs. Most grafts in the human scalp consist of two follicles. Quantity of such grafts exceeds 50%. Grafts with 1 or 3 follicles are less common. Four hair follicles are observed in no more than 3-4% of cases. The grafts that contain more than 4 hair bulbs are very rare.
Grafts are extracted from the occipital region. During the procedure a doctor looks, whether it will lead to the significant hair thinning. If the number of follicles is not enough, they can be also taken from the chest and chin.
