Every so often, the techniques and treatments used to treat alopecia are further refined. Hair transplantation has been improving its processes, and has produced new techniques such as the FUE technique that involves follicular unit extraction in order to graft the units onto areas of the scalp suffering from baldness. It can be interesting to find out what does follicular unit extraction involve. When the FUT technique – the removal of follicular units in strips – first appeared as the principle method for preforming hair transplants, scientists did not stop evolving their experiments to improve the process. And as a result, the FUE technique was born. This method is now preferred among patients and specialists due to its many advantages.
What is the FUE technique?
It is the latest hair transplant technique to be used in the fight against baldness, and is characterized by the extraction of individual follicular units from the scalp, that are then grafted to areas showing signs of baldness. The birth of this technique represent a radical change in the way hair transplants are preformed, in that they no longer require large surgical procedures, and they have dispensed with the scalpels and sutures that were needed to carry out transplants using the strip method. The execution of this procedure requires a special instrument, whose diameter varies between 0.8 and 1.2 millimetres, and that allows each follicular unit to be extracted individually. This helps avoid the tedious procedure of removing a strip and separating out each of the follicular units.
What are the benefits?
Patients have said that the procedure is more effective, as it does not leave any visible scarring so they can cut their hair in any style they like. This is one of the main problems with transplants using strips, as they leave a lineal scar on the scalp. Another advantage is that it is possible to plan the surgery in more detail, taking control over how many follicular units are extracted from the scalp, so not a single one is wasted. The FUE technique also requires a very short and less intensive recovery period, as the patient does not need any suture and the scars are virtually imperceptible. The patient can return to normal activities very shortly after a session, and can continue or repeat the process whenever they like, due to the recovery time being so short.
What are the disadvantages?
Although the results are effective, the method does have a few drawbacks, such as the duration of each session, which can be much longer than with the strip method. The specialist extracts the follicular units one by one and grafts them in the same way. This can lead the patient to experience high levels of fatigue. Equally, the complexity of the procedure makes the technique more costly. In some cases, the follicular units do not survive a long time in the recipient site as they are removed with a very small amount of scalp tissue. This causes the adhesion to last less time.
Why choose it?
Despite of the disadvantages of the procedure, there are many reasons to choose this method. The first is the fact that it leaves no trace. This is particularly attractive to many patients, as they will not be left with unsightly scars on the scalp. Likewise, those patients who can not spare a long time for the recovery process usually opt for the FUE technique, which involves a longer extraction process, but a much shorter recovery time. There is another group of patients that choose this technique to avoid the appearance of scars, which can be caused by erroneous surgical procedures.
