FUE - Follicular Unit Extraction
The main difference between FUE and FUT is the extraction technique used to harvest follicular units. In FUT or strip method, you are given local anaesthesia in the donor area of your scalp (usually the back) where the hair never undergoes balding and a strip of scalp skin with hair is cut. The donor area is then sutured. This typically leaves a fine scar that's easily hidden by your remaining hair. The follicular units are then removed from the donor strip under microscopic control and divided into natural groupings of one, two and three hair follicular units.
In FUE, we still use the follicular unit approach to hair restoration, but instead of removing a donor strip, we remove one individual follicular unit at a time. The instrumentation (0.8-1.0 mm punch) we use is so small that the donor area is left with tiny, almost invisible dot marks.
Advantages of FUE over FUT
- No linear scar
- No need for sutures or surgical clips
- Good choice of procedure for patients who wear short hair
- Good option for patients with previous scarring or a tight scalp
- Good choice if a limited number of grafts are required
- Faster healing
- Minimal discomfort after surgery
- Less downtime and able to resume normal activities and exercise quickly
- Useful for repairing donor scarring
- Makes it possible to harvest other hairs such as beard or body hair.
Disadvantages of FUE
- Larger donor area is required to harvest bigger cases
- Grafts are out of the body for longer time than FUT
- Quality of harvested grafts is debatable whether equivalent to FUT
- FUE is more expensive
