The FUE technique (Follicular Unit Extraction) is based on the extraction of the follicular units, one by one, to implant them in the hairless areas of the scalp. This method can be applied for rebuilding eyebrows, hiding scars, etc. It is performed under local anaesthesia, it is not painful and the patient’s recovery is usually easy and quick. It offers great advantages because it is not invasive, working at a more superficial level than other procedures, it does not leave stitches, and it is a technique that allows treating small and medium size areas. To do this, the donor area, usually the lower part of the neck is shaved and the scalp units are removed one by one with the help of a thin calliper of less than 1 mm in diameter. At the moment, this technique is considered the most advanced hair transplant technique that exists in aesthetic medicine and the one that offers more natural results.
