Hair Transplant: The hair transplant by means of the FUEtechnique (Follicular Unit Extraction or "individual extraction of follicles") is a systematic and artistic redistribution of the hair follicles, which involves inserting small grafts of the scalp that contain the so-called "follicular units". These grafts are obtained under local anaesthesia from the donor site, namely the back and/or side area of the scalp and they are then implanted into the recipient site by means of making micro incisions, according to the design previously agreed upon with the patient. Having obtained the grafts from the back and side areas of the head, which have the hormone receptors that are not affected by the enzymatic hyperactivity, once grafted into other areas they do not fall out and they continue to grow normally.
