There are a few different micro-grafting techniques, but the main idea behind them all is taking very small amounts of hair and doing thousands of mini transplants on the scalp.
The first is Follicular Unit Transplantation (FUT). Numerous thin strips, known as micro-grafts, are removed from donor sites (typically the back and side of the head) and transplanted in naturally occurring groups of one to four hairs, also known as follicular units. This is one of the more prevalent types of hair restoration. A huge advantage with this procedure is the rate of survivability with follicular units.
Another more precise type is Follicular Unit Extraction (FUE). In this procedure individual follicles are removed from donor sites, preferably one at a time, and transplanted into the recipient site.There are a few advantages of FUE. First, it looks more natural than FUT or other types of transplant techniques. Second, donor sites aren’t just limited to the scalp, with chest, legs, arms, abdomen, back, face, and beard being acceptable as well.
Follicular Isolation Technique (FIT) is ideal for patients that wish to keep a very short hair cut, or for those who desire a less invasive alternative to strip harvesting. The process isolates certain follicle groups in the donor area and carefully removes them with a small surgical utensil. The follicular unit grafts are placed into tiny incisions recipient areas. The donor sites heal on their own, without visible bandages. Once healed, the scalp usually shows no visible evidence of surgical procedure.
