What does a hair transplant consist of?
Hair transplantation is a minimally invasive surgical technique that allows to improve hair density in patients with different types of alopecia. The technique of choice is hair transplantation with micrografts, in which follicular units (UF) are transplanted from the occipital region (genetically more “resistant” to alopecia) and implanted in the areas of alopecia.
Hair transplant as therapy
Hair transplantation is a therapeutic tool that should never replace medical treatment, but should be used as a complement to it.
Hair transplant surgery is a surgical technique that is performed in the operating room with local anesthesia and the entire process is performed on the same day. It is a surgery that does not require admission and the patient’s medical recovery is quick.
The transplanted micrografts initially look similar to short hairs with a scab, and from 2 weeks after surgery the hair stems will shed. It will be after 5-6 months after the surgery that the new follicles begin to grow and the patient will progressively improve the hair density until one year after the transplant, at which point the final result is usually seen
Types of Capillary Micrograft Surgery
There are 2 techniques to perform hair transplantation with micrografts; the strip technique (also called the “FUSS” technique or the “strip” technique) and the FUE (follicular unit extraction) technique:
1. Strip technique:
It consists of removing a strip of skin from the occipital region, the defect of which is closed with direct trichophytic suture. This technique does not require shaving the hair, but special care must be taken in patients with very short hair, as the scar from the donor area could be seen.
2. FUE technique:
It consists of extracting the follicular units one by one from the occipital region by means of small punches of 0.70-1 mm, for which it is usually necessary to shave the patient’s hair. The small defects that remain where the follicular units have been removed close by second intention and are hardly noticeable. It is the most widely used technique today.
Once the follicular units have been obtained, the next step would be implantation in the receiving area. To perform the implantation, the incisions (holes where the Ufs will be inserted) are previously made. And then the Ufs that we had previously extracted are inserted.
