3 surgical hair follicular extraction techniques are used in modern hair transplantation:
- FUT technique
In this Hair Transplantation technique, a linear series of follicular units are removed from the donor area. A trichophytic closure is used in the donor area so that only a minimal linear scar less than 0.4mm- 0.5mm remains undetected even with a haircut no less than 0.5cm hair. Stereoscopic microscopes are used to prepare the hair follicular units and then follows placement of the grafts in the recipient area.
- FUE Technique
In this hair transplantation technique, individual hair follicles are extracted one by one from the donor area with special cylindrical tools of 0.7-1mm diameter. This technique does not require the use of a suture. Small, not easily visible (less than one millimeter for each hair follicle removed) scar – like white dots – remain and are easily covered by hair. After removal, the hair follicular units are further prepared with special microscopes.
- Body Hair Transplantation (BHT)
The Body Hair Transplantation technique (BHT) is similar to the FUE technique. Hair follicles are removed from areas of the body other than the donor area on the scalp.
The most important thing to remember is that the only difference between the two basic techniques, FUT & FUE, is how FUs are removed from the donor area.
All other surgical steps are the same.
Also remember that there is no “old” and “new” technique, as both techniques developed from older techniques and are constantly evolving.
