Follicular Unit Transplantation

Pattern baldness is a problem faced by both men and women. There are several reasons for hair loss though heredity is the major cause. Some people who are genetically predisposed to baldness have testosterone in their hair. In their case the hormone gets converted to dihydrotestosterone (DHT) by 5-apha reductase, an enzyme.

It is seen that DHT causes weak hair. In several cases it results in pattern baldness. There are other causes of pattern baldness, too. In the case of pattern baldness people often go for a hair restoration surgery like scalp flap surgery or scalp reduction surgery.

What is follicular unit transplantation?

There are several methods of hair restoration surgery. Follicular unit transplantation is a very effective method used in the case of hair loss. It is also widely used. The operation of follicular unit transplantation involves transplantation of hair from the permanent zone in the back of the scalp into areas of the scalp where there is no hair growth. It is done using only the naturally occurring, individual follicular units.

In follicular unit transplantation the donor tissue must be removed from the back of the scalp in one piece to prevent any damage. Single strip harvesting is thus a very important part of this hair restoration surgery. In this hair transplant procedure there is use of small recipient sites.

In follicular unit transplantation all of the follicular units are removed from the donor tissue under total microscopic control to avoid damage. The stereomicroscopic dissection used in this hair restoration surgery produces an increased yield of both the absolute number of follicular units, as well as the total amount of hair.

FUT and mini-micrografting

The procedure of follicular unit transplantation is different from the minigrafting and micrografting techniques of using a multi-bladed knife that breaks up follicular units and causes unacceptable levels of transection of hair follicles.

Graft sizes are determined by nature in follicular unit transplantation whereas in mini-micrografting the graft sizes are arbitrarily determined by the surgeon who cuts the donor tissue into pieces.

In mini-micrografting neither preserving follicular units nor keeping hair follicles intact are felt to be important. In this hair restoration surgery a multi-bladed knife is used to quickly generate thin strips of tissue and then direct visualization is used to cut the tissue. This procedure is cheaper and takes less time compared to follicular unit transplantation.
