WHAT IS HAIR TRANSPLANTATION?

Micrograft/minigraft hair transplantation involves the transfer of tiny segments of hair-bearing skin from the permanent fringe area of the scalp (‘Friar Tuck’ area) to the bald area and is now a standard international technique. It was initiated in Australia before becoming popular worldwide. The grafted hair is permanent. Minigrafts and micrografts contain from 1 to 3 hairs. ‘Micrograft’ is the term applied to the smallest minigrafts.

HOW IS IT DONE?

Thin strips of hair-bearing skin are removed from the permanent fringe area of the scalp (‘donor’ area) and divided into hundreds of tiny hair grafts. These grafts are then carefully transplanted to the bald area. The transplanted hair begins to appear within 8 – 12 weeks, with uniform growth by 4 – 6 months. It is performed under local anaesthesia and is usually carried out over a series of sessions, each taking from 1 ½ to 4 hours, depending upon the number of grafts inserted. Common numbers are between 300 and 500 grafts per session. The interval between sessions varies from several weeks to several months.

OTHER TECHNIQUES

Micrograft/minigrafts have replaced the early grafting technique known as punch grafting. Punch grafts involved the transplanting of relativey large, circular grafts, each containing up to 15 hairs. Whilst providing superb density and coverage, punch grafts often did not produce an aesthetic, natural looking hairline.

In recent years there has been interest in follicular grafts. These are grafts of one hair from which all surrounding tissue has been stripped away, leaving the bare follicle and hairshaft. The vaunted value of follicular grafts is that they can be transplanted much closer to each other, supposedly allowing a greater density to be achieved in a single operation. Critics of ‘mega-sessions’ of follicular grafts claim that, although the technique is superficially attractive, the removal of tissue surrounding the follicle is detrimental to its survival.

Experience indicates that important conditions for any type of graft to survive and thrive are a short interval between harvesting the grafts and their insertion in the bald area, adequate spacing of the grafts so as not to threaten scalp blood supply and the rapid perfusion (nourishment) of individual grafts once transplanted.

Several sessions of hundreds rather than thousands of grafts may well be safer in producing a better eventual result.

Some mega sessions of follicular grafting, packing grafts in close proximity to each other, have resulted in overload of the scalp blood supply, loss of grafts, and replacement of scalp skin with scar tissue.
