After all, hair transplant is a surgery, where knifes are essential tools to perform the job. As a result, the generation of scabs and scars is unavoidable. There are differences though. When the Follicular Unit Transfer (FUT) method is used for the hair transplant scarring can cause a much more serious problem. In the Follicular Unit Extraction (FUE) method this issue is not so disturbing. Here is why:
Difference between the FUT and FUE method relating graft harvesting
When using the FUT method the surgeon cuts out a fairly large peace (a strip of about 30 cm x 1 cm) from the rear and lateral parts of the scalp in order to get the necessary quantity of grafts. (The graft is a follicle unit that contains 1-4 hairs, which share the same follicle and other skin structures.) This cut is made practically from ear to ear and it is so big, that it has to be stitched. Of course, traces of this large wound cannot be cleared away totally. After its healing, a hair length of at least 1 cm is needed to cover the scar remaining in the scalp.
The situation is totally different in FUE method. In this procedure the grafts are taken out from the scalp one-by-one using a very fine surgical chisel. Quite naturally, the wounds are much smaller than in the case of the FUT method and they are distributed over the occipital part of the scalp therefore the scars left in the skin are almost undetectable. Even a hair cut short can cover these little scars.
The implantation procedure
As to the implantation, there is no difference between the FUT and FUE methods. In both cases small, fine incisions are cut into the bald area of the scalp in order to prepare the place for each graft to be implanted. In this way, depending on the quantity of the grafts, 1000 – 3000 small cuts are made in the scalp. Although they are very small and fine, still they are wounds. Infections may occur in them hindering the healing process. However, thanks to the fact that the patient’s own follicles are transplanted, these infections can be cured relatively easily as no rejection threatens. When finally the healing process takes place scabs are generated on the wounds, but these scabs can be simply washed off as the healing continues. All that are left from the surgery are very small, almost invisible scars in the scalp.
Of course, the transplanted hair falls out in a few days after the surgery, due to the shock caused by the operation and transplanted follicles also need some time to settle in their new place. But after this transitional period the new hair grows out and it covers even these hardly visible scars.
