The hair transplant procedure is technically divided into two types, namely the FUT (Follicular unit transplant) and the other one is the FUE (Follicular unit extraction). The procedure of hair transplant involves the shifting of hair roots from the donor portion to the recipient one in such a manner that the donor portion is utilized with a careful decision in order to offer the aesthetic effect of the procedure.
FUT Hair Transplant
The follicular unit hair transplant involves the excision of the strip of skin for getting the hair roots from the safe donor area, usually from the back and sides of the scalp. We are using the word safe donor area for the back and sides of the scalp as these areas of the scalp are resisted with the effect of the DHT hormone that causes a severe hair loss. The DHT (DI-hydro Testosterone) hormone of the body is a converted form of the testosterone (male sex hormone), which is affected by the enzyme named 5-alpha reductase and gets the synthesis form of DHT from testosterone in the areas like the prostate and hair follicles. The DHT causes a severe hair loss and the condition of male pattern baldness and the female pattern baldness is occurred to present the cause of baldness. The excision of the strip of skin’s main motive is to get such type of hair roots for the implantation procedure that is destined to remain permanent in nature and never tends to fall.
The FUE Hair Transplant
The Follicular unit extraction is a procedure of hair graft extraction one by one with the use of modern punching machine that needs a careful attention and forecasting skills to target the single hair grafts at a single time. This technique of the hair graft extraction is also known as the blind technique as there is not known of the root direction and angle because the punching is made from the outer skin of the scalp and nobody exactly tell about the position, angle, direction and shifting of different types of hair grafts below the skin of the scalp.
What is the damage in the hair restoration and how is it controlled?
Damaging of hair roots are a common phenomenon during the procedure of hair transplantation, it can be controlled or make, the less if proper care and consciousness will be applied at each step of the restoration procedure. It is mandatory that a hair transplant surgeon is well-versed, extremely qualified along with an extreme sense of aesthetic skills to put the hairline design as according to the patient’s age, sex, facial profile and their available donor portion. The technicians should also possess a number of years’ experience in order to offer the greater output of the procedure in terms of saving the number of grafts.
Damage of hair grafts can be possible at any step of the procedure, whether it is harvested/extraction, dissection or handling the grafts for the implantation procedure. The damage of grafts is higher in the case of the FUE hair transplant as compared to the FUT hair transplant because the punching is made randomly from the unsafe areas also results in the less sustainable hair roots as well as the damages during the punching itself as the angle and direction are not cleared from the outer of the skin.
As far as FUT is concerned, the possibility of damaging the hair roots is very less and can be controlled up to 99% if the best hair transplant Surgeons and the trained technicians along with the advanced technology are there to support the aesthetic effect of the hair transplant procedure.
How to Reduce the damage rate in the FUT Hair Transplant Procedure?
1. Careful Incision for the Strip Excision
The strip should be excised minutely with the minimum depth of 3-4 mm from the scalp skin in order to avoid the damages of the grafts origin and only catch the extreme outer layer by the hook to get the collection of the grafts for the implantation procedure. In this way a good hair transplant Surgeon can save the 500 grafts during the strip harvesting step.
2. Proper use of higher Magnifications
If there is use of the magnification of microscopes during the graft dissection step the graft can be saved up to 99%. The good hair transplant centre uses the 20X magnifications of German microscopes and 200X magnification of video-assisted microscopes to avoid the damage rate while the dissection under the practice of the trained technicians.
3. Handle with care while holding & placing the Grafts
It is a considerable point in the hair restoration procedure that the grafts should hold from the shaft side and not from the root side while placing it in the saline water to make it viable till implantation. The second step where it is needed to hold the graft is the implantation step when Doctor places the grafts in the recipient zone and in this step the same point should be considered to avoid the damage rate of the graft.
4. Trained Technicians
Since the step of the dissection and harvesting the strip is required to have the technicians who help the surgeon to complete the task and they must have such training to make possible the process of dissection of grafts with precision, holding the graft with care and harvesting the strip with the quite care and consciousness to support the aesthetic outcomes of the procedure.
