Σε ευχαριστώ για την απάντηση, αλλά νομίζω πως δε λέει αυτό. A common question among the hair transplant enquiry is how long does the transplanted hair last. There is a paucity of research on this subject.
The aim of this study was to assess the longevity of transplanted hairs after FUT.
The longevity of the hair follicles after FUT is still debated; there are no studies to document the life term of the transplanted follicles.
These findings of the reduction in the density of the transplanted hair, even though they were harvested from safe donor area, question the theory of donor dominance. The influence of recipient area on the transplanted hairs has been documented in Hwang’s[
1] study of grafting the scalp hair to the leg and vice versa. These findings raise the following questions: Does the theory of donor dominance hold ground? Will the recipient site influence the transplanted hairs? Is there any genetic variation in the results of hair transplantation among various races? Another possibility for the reduction in the density of the transplanted hairs could be due to synchronization of the hair cycle post surgery. Synchronization is not clearly documented in the literature and is known to occur at the end of 2 years, and these follicles regrow after a lag period.[
2] The findings in our study do not seem to be correlating with synchronization. It has been found that the miniaturization does affect the occipital donor hair, and this may be the cause of reduction in the density of the transplanted hairs. Usage of minoxidil and finasteride and their influence in the longevity of the hair follicles in our study were not statistically significant. The limitation of this study was that the hair density counts could not be done in the subjects as this was a retrospective study.
