HAIR STEM CELL TRANSPLANTATION
It is interesting to be able to compare a transplant performed with the technique of extraction of follicular units, commonly known as FUE, with an HST hair stem cell transplantation. Indeed, the FUE is extremely well known, while the HST is still little known.
The concept of the FUE technique is that to be realised we must consider the size of the donor area. That is, the area in the occipital part of the skull in which follicular units are growing and that are not sensitive to dihydrotestosterone and are therefore not likely to fall out.
This donor area constitutes the capital available to the patient for the transplantation. In fact, the FUE technique removes entire follicular units from the donor area and moves them to the recipient area. This is how the so-called capillary restoration is carried out.
Limits of the FUE technique
It is therefore clear that the limitation of the FUE technique is the number of follicular units available in the donor area. If a donor area is rich, if it has many follicular units, the chances of a good restoration become greater than if this donor area is sparse.
All this, however, depending on the surface of the area to be restored. The larger the area to be restored, the more follicular units are needed to be taken from the donor area. It is therefore clear the relationship between the possibility of restoration and the richness of the donor area. If a donor area is rich, the patient can afford to collect a substantial number of grafts. But if the donor area is sparse, the patient probably can’t even afford a transplant.
FUE moves the follicular units but does not regenerate them
So, the first concept to consider is the fact that FUE performs a simple migration of follicular units from point A to point B. The removal of follicular units from the donor area is an element in which the competence of the surgeon is measured. In fact, if the removal is carried out too concentrated, in the end the result will be visible. The surgeon should carefully distribute the samples over the entire donor area, to minimize the visual impact that these samples can have by decreasing the density.
One of the most serious mistakes a surgical operator can make is that, in fact, he does not know how to carefully distribute the samples. In this case we see that the donor area has been removed and therefore we notice a decrease in density. It should be considered that a graft leaves a void where it is extracted. And all these samples, and therefore all these voids, ultimately limit the patient’s ability to wear short, shaved hair because his donor area would be dotted with a huge number of voids.
FUE technique not recommended for young people
The fact that the donor area is limited in the number of follicular units available, constitutes a limitation to the possibility of intervening on a young patient. A young patient has alopecia that progresses over time.
So, if he performs FUE surgery at a young age and consumes a substantial portion of his follicular unit capital, at a more mature age, if his alopecia has become more prominent, he will probably no longer have enough follicular units available to achieve acceptable restoration.
Hair stem cell transplant overcomes the difficulties of FUE
HST hair stem cell transplantation overcomes all these difficulties or limitations that FUE unfortunately presents. Instead of taking an entire follicular unit, only part of it is, acting with a very small needle. The stem cells, contained in the follicular unit, are thus divided into two groups. Each of these groups will then give rise to a new follicular unit identical to the previous one. Then, from a follicular unit, 2 are created to restore the donor area and to fill the recipient area. The first advantage that becomes clear is that we have no capital limitation of available follicular units.
Regenerated donor area
The donor area that regenerates in 9 months can afford to offer follicular units for transplantation indefinitely. The donor area regenerates, so it is no longer dotted with voids as we have seen being present in a FUE intervention.
No losses, no scars
There is no shortage and there are no scars either. Thus, the donor area regenerates exactly as before any extraction. The type of transplant is also suitable for young people. Because we have seen before that alopecia, gradually increasing over the years, can be restored with subsequent transplants, without the capital of the follicular units decreasing. There is therefore no problem in distributing withdrawals wisely, because in any case these withdrawals postpone back. The result is extremely natural. And the fact that you act with extremely tiny needles means that the result is of a great natural.
Therefore, compared to a HST procedure, the donor area becomes virtually unlimited , and the patient may therefore be allowed to restore even very large areas that would not otherwise be possible to restore.
