Follicular units are a bundle of hair growing together. A follicular unit is usually formed of one to four terminal hairs. Every follicular unit is surrounded by one to two fine vellus hair, oil glands, a small muscle and a fine band of collagen. The follicular unit is the skin’s hair-bearing structure ensuring maximum growth. It looks like a well-formed structure under the microscope.Visit FUE Hair Transplant NYC for more details.
In genetic balding the transplanted hair is of smaller diameter and length than the hair replaced. It is highly advantageous to use individual follicular units. It facilitates the use of very small units. At the same time the amount of transplanted units is proportionately much large. Therefore a surgeon can place up to four hair strands in a tiny recipient site. It has tremendous implications for cosmetic surgery in general.
This gives follicular hair transplant a considerable edge over micrografting. Transplantation
of individual follicular units also gives a natural look to the transplanted hair.
In hair follicle transplant, individual follicular units are directly removed from the donor area. It means that this method is independent of linear incision. The surgeon uses a 1mm punch to make a small circular incision in the skin around the upper part of the follicular unit. It is then directly extracted from the scalp.
Very often follicular unit extraction (FUE) and follicular unit transplantation (FUT) are treated as two different things. It’s wrong. FUE is basically a type of FUT in which the follicular units are extracted directly from the scalp, instead of microscopically dissected from a strip that has already been removed. In follicular hair transplant the individual follicular units can be obtained either through single-strip harvesting and stereomicroscopic dissection or through FUE.
Follicular transplant preservation
In follicular hair transplants it is crucial to keep the individual follicular unit as it is. Neither the unit should be broken up into smaller units nor combined with larger ones. This is a ground-breaking development in the history of cosmetic surgery. Often hair transplant surgeons combine several follicular units or split them up.
Follicular hair transplant and mini and micro grafting
There is similarity between follicular hair transplant techniques and those followed in minigrafting and micrografting. However, follicular hair transplantation is different from mini and micro grafting. Both of the latter procedures use a multi-bladed knife to split the follicular units. This results in unacceptable levels of transaction of hair follicles. In follicular unit transplantation it is the nature that determines the graft sizes. In mini-micrografting the graft sizes are arbitrarily determined. The donor tissue is sliced to the size the surgeon considers fit. There is another difference between follicular hair transplant and mini-micrografting. In the latter neither the hair follicles are kept intact nor the follicular units are preserved. In mini-micrografting, speed and economy of the procedure are more important. The process entails using a multi-bladed knife to quickly generate thin strips of tissue.
