Medical terms in the field of hair transplantation

Very often, we notice some confusion about the technical terms in the consultations. We will try to describe the most important terms as simple as possible:

Graft:
When you look more closely at your partner’s scalp, you will notice that more than one hair can often grow out of a hair canal. Each hair from the canal has its own root in a particular skin depth. All the hair from a canal, along with its roots, is called a graft. The doctor always takes out grafts and never single hair from a hair canal.

Hair follicles:
These are two layers that surround the hair roots. They ensure the attachment of the hair to the skin. One can imagine the hair follicle as a skin-hose, which determines the growth direction of the hair-shaft by its slight inclination. Thus, different curvatures of the hair follicles can be found in different hair types. The glands which produce sebum and odor are found here. There are tiny muscles set in there, which can pull up the hair (goose bumps). Many nerve fibers also end in hair follicles, which serve the sense of touch.

Hair root:
The portion of hair that lies within the skin. It is about three millimeters deep and lies in the skin of the leather, but it can also extend into the subcutaneous fat. The lower end is thickened like a bulb and is called a hair bulb.
Due to the different curvature of the hair follicle and different depth of the hair roots within the skin, the FUE technique is a blind process, which requires high precision and experience of the hair surgeon.

FUE:
Follicular Unit Extraction = Obtaining Follicular Units (Grafts)
This is also referred to as a single hair method.

Local anesthesia:
Local anesthetic. This is done twice during the procedure. Once in the donor area and once in the reception area. Each last about 4 hours. It is performed superficially with a very thin cannula and has the same circumference as a cannula with which diabetics inject insulin. The feeling of pain is therefore tolerable.
