Hair transplantation means, transplanting live hair roots onto the bald area.(RECIPIENT AREA). These transplanted hair roots behave in the same manner as the hair from the area where they are extracted. These transplanted hairs after growth can be cut or trimmed regularly. These can be shampooed or dyed if required. These hairs don’t require any medicines to maintain the growth as it occurs naturally and permanently. Even after complete shaving or tonsuring, these hairs will grow back and tend to do so for the rest of the life.
Transplanted hair roots should be bald resistant. And these bald resistant hair roots are usually present on the back or sides of the scalp (DONOR AREA).
The density of the hair depends on the number of grafts present per sq. cm. Each sq. cm area of normal scalp contains more than 80 follicular units. Hence, in the bald area, more the number of grafts transplanted the denser the appearance. More than 40 follicular units per sq. cm should be implanted to give the natural look. Transplanting around 40 FU s/sq. cm is not an easy task as it requires lot of technical skill. This particular skill of hair transplanting more number of grafts is called Dense Packing.
The process of hair transplantation is done in sessions if the area to be covered is more.. Transplanting more number of grafts at a single session can be termed as Mega and Super Mega sessions depending upon the number of grafts transplanted.
Mega session means transplanting >2000 follicular units (3500 follicles in a single session and super mega session comprises of transplanting > 2,800 follicular units ( 5000). A session can be termed as Giga Session, if >5000 follicular units ( 8000 follicles) have been transplanted at one go.
All the above mentioned processes can be successful only in centers that have many surgical assistants who are well trained and adept at utilizing the latest equipments available, to their best.
Follicular unit transplantation can be done by two methods.
