Let’s try to answer the question we hear the most: but doctor, does transplanted hair fall out ? The short answer is no. But here we tell you the long answer.
The androgenetic alopecia or baldness common is the loss of hair hormone action in patients predisposed genetically . It is proven that the hair follicle is under hormonal control since the enzymatic action of “5 alpha reductase” is responsible for the transition from testosterone to dihydrotestosterone and produces an acceleration of hair cycles that leads to premature depletion of the hair.
The hair transplantation is a redistribution both systematic and artistic of hair follicles and is the introduction of small grafts of scalp containing calls follicular units (groups 1,2,3 or 4 hair follicles it as come naturally determined). These grafts are obtained from the back (occipital) and / or lateral (temporal) parts of the scalp, which are the so-called donor areas, and after carefully preparing them under high-resolution microscopy, they are introduced into bald or sparse hair areas that would be the called receptor zones .
By obtaining these grafts from these posterior and lateral areas of the head, genetically programmed to grow throughout life by having hormonal receptors that are not affected by enzymatic hyperactivity , it is achieved that once they are grafted in the recipient areas they do not fall and continue developing normally their hair cycles and growing normally.
So does the transplanted hair fall out?
It is considered that the transplanted hair is a definitive hair, although it is also true that like the non-transplanted hairs of the rest of the head are gradually lost due to aging , some transplanted hair are not alien to this natural process and can also be to fall over the years.
In this sense, it is estimated that a small percentage of the transplanted hairs will be lost due to aging, although the dynamics of fall is much lower than that of the hair in the anterior, upper and crown areas, which, as we have commented at the beginning, are under influence. hormonal and genetics.
Telogen effluvium, shedding or shock loss, after a hair transplant is a temporary circumstance caused by stress with which you have to be patient and wait a few months, during which in some cases, we can apply a PRP treatment in the area with telogen effluvium .
Finally, and always to transmit the greatest possible safety to the patient , obviously concerned about his hair restoration process, we would like to end by remembering that the hair loss caused by alopecia has nothing to do with the effluvium of the hair that can occur after a hair transplant. The effluvium in transplanted hair is the loss of hair that can occur in the first weeks after hair transplantation as a result of the post-surgical trauma to which we subject them with the entire process (extraction, preparation and implantation). Once it enters the resting phase, a new anagen or growth phase begins from approximately the third month after hair transplantation. From here on, the grafted hair continues to develop its hair cycles normally.
