There are two types of hair surgery.Follicular unit transplantation and follicular unit extraction (Robotic Hair Transplantation)

The FU is identified an atomically as a small bundle consisting of 1 to 4 hair follicles, full-thickness as well as fine hairs, and the oil glands, muscles and connecting tissue that accompany and support hair follicles.

A recent development in surgical hair transplant surgery is to specifically use the FUs for transplantation. The FUs are removed from the donor site (usually on the nape of the neck) by using a harvesting technique that preserves the FU intact. One such technique is called single-strip harvesting and is done with a scalpel-like blade.

The extracted FU may be used intact, or may be divided into smaller units for transplantation. Single follicular units are often used to fill in a hairline, multiple FUs to provide greater density in the center of the scalp. The FUs are transplanted into the scalp by inserting them into small slits incised into the skin and underlying tissue with a small blade or needle.

Another method is called follicular-unit extraction (FUE) or Robotic Hair Transplantation. FUE is performed by using a punch-like "circular scalpel" to score the skin and mid-dermis to a level of about 2 millimeters around a follicular unit, then gently extracting the FU from within the scored circle.
