Basically hair restoration is carried out by relocating hair from a thick place to the scanty place. Follicular grafting strategy was the first hair transplantation technology carried out to restore fallen hair. A follicular unit is the smallest biological unit of hairs. It consists of 2 to 5 hairs. These follicular units of hairs are plucked from a sheath of fatty tissues existing on the back of the scalp. As hair for transplantation is collected from this area, it is known as donor area. In the older method one graft consisted of 7-12 hairs and they looked unnatural hair plugs. There are two methods of hair transplantation. They are follicular unit extraction and follicular unit transfer. These two hair transplantation methods commonly practiced in hair transplant centers are explained below.
Follicular unit extraction: In the hair restoration procedure (FUT), the skin from the donor area, which is usually the back of the head, is removed as a strip. With the help of a microscope the follicular units are separated from this strip. These donor hairs are individually planted in the tiny ports prepared using microscope in the recipient area. One strip of 20 cm width usually contains 1500-2000 follicular units. The wound left at the donor area is closed with suturing and it leaves a scar mark there. This procedure usually done in hair transplant near me centers is very fast compared to the other procedure known as FUT and is less costly also.
Follicular unit extraction (FUE)
In this procedure follicular units of hair are extracted individually from the donor area through a long and strenuous process. This process does not necessitate any skin cutting or removing skin strip. This is carried out by plucking hair follicles one by one using special devices. It is a very strenuous process and requires much time. These extracted follicles are then planted on the recipient area in the pores already made. In this case, as follicles are extracted one at a time it takes much time for extracting sufficient quantity of grafts. It also leads a time lag in replanting the grafts resulting in non survival of grafts after transplanting.
Problems associated with hair restoration
For restoring the lost hair on particular portion of the head, the patient should have sufficient density on some other part, usually the backside of the scalp area. There are some other factors for the hair to become eligible for accepting as donor hairs. Future baldness possibility of the head would be taken into account before plucking hair from the donor area.
The hair removed retains the baldness characteristics of the person concerned. So, one cannot completely deny the possibility of affecting this problem to the transplanted hair. Proper assessment about the donor hair plays a crucial role in the surgery related to hair restoration.
