Follicular Unit Extraction

Hair transplant is a medical technique used to treat baldness performed under local anesthesia without hospitalization. It involves harvesting hair roots located at the back (crown) and sides of the scalp and replanting them in the bald or thinning areas. Once implanted, grafts will grow new and resistant hair that will continue their hair growth cycle for life.

Hair transplant can therefore be compared to a redistribution of the patient’s ‘hair capital’ in the crown area, it is about managing this capital by changing the distribution between the occipital zone, the donor zone and the area to be treated, the recipient zone.

This hair capital is very valuable and should not be wasted, which is why the hair micro-transplant treatment should always take into account the future evolution of hair loss. Anticipation is one of the essential rules of the success of micro-grafts. Filling in the gaps is not enough; it is also necessary to get ahead of what will happen and treat accordingly in a preventive way the areas where the hair will fall, especially for young patients who sometimes need a second subsequent hair transplant. For these patients, adequately anticipating hair loss will allow them to enjoy normal hair throughout their life.
Hair transplants often lead to a new quality of life, it is therefore necessary to ensure that any procedure is preceded by a detailed consultation and that the treatment is always performed by an experienced and competent doctor.

The pre-operative consultation

The medical consultation is a very important and essential step before a hair transplant. During this consultation, a detailed and thorough discussion allow patients to learn all the important information concerning the causes and treatment possibilities of baldness.

Dr.Seffen will meticulously examine the hair density of your crown, the texture of your hair, perform a capilloscopy (examination with a camera associated with a software to assess your hair and scalp: appearance of the hair, diameter, densitometry, condition of the scalp (sebum level). He will ask you your wishes in terms of future hairstyle, all the questions necessary to establish a medical record and he will clearly tell you what is and what is not possible in order to achieve a reasonable and aesthetically successful strategy, in the short, medium and long term.

Follicular unit extraction (FUE) is a technique allowing hair to be removed from the donor area using 0.75-0.95 mm diameter punches and manually perforating the skin at the crown of the previously shaved head.

The obvious benefit of the FUE technique is the fact that it avoids a linear unsightly scar at the donor area (which is the case with the outdated FUT technique). Instead, the FUE hair transplant only leaves microscopic traces becoming completely invisible 48 to 72 hours after the procedure.

Perforating the skin for graft implantation requires extreme skill and precision of the practitioner to preserve the integrity of the follicular unit when removing it, which is why Dr.Seffen only uses extremely sharp manual punches. These punches offer control of the drilling movement and avoid deep sectioning of the graft or heating the skin, which happens with extraction machines used for FUE hair transplants.

The procedure

Patient Preparation

The patient’s hair is first washed to remove impurities and their lubricating film produced by the sebaceous glands of the skin. Typically, the scalp is shaved for a FUE hair transplant. Hair in the harvesting area should be short enough (about 2mm) to allow the Punch to slide over the hair shaft without any constraints. Shaving the hair shirt reveals the true exit angle of the hair or follicular unit, which allows the Punch to be aligned so as to avoid sectioning of the grafts.

Extraction / Implantation

Once prepared for the procedure, the patient can choose a lying position or sit on a chair. The edges of the donor area and recipient area are usually drawn beforehand. Local anesthetic is injected in the scalp, after which the procedure can begin. The harvesting step of the procedure involves alternating between the same two actions: separating a series of grafts from the scalp using the Punch and then extracting them using micro-forceps. Depending on the speed of the practitioner and his assistants, it is possible to extract 400 to 700 grafts per hour. Hair transplantation is sometimes performed by two surgeons simultaneously on both sides of the patient’s scalp.

Micro-perforations (to place follicular units in the balding area) are made in the scalp using a micro-needle. During hair implantation, the patient can watch TV, read a book or listen to music to pass the time. Graft implantation can take several hours depending on the number of grafts desired. Once the follicular units are implanted, the scalp is cleaned and inspected by Dr.Seffen. The patient will receive specific postoperative instructions as well as a medication prescription.

Benefits of the FUE hair transplant

Because the FUE hair transplant technique does not leave a linear scar, it adapts well to people who usually cut their hair short. It is also an asset for patients who are often involved in intense exercise such as high-level athletes who need to resume training quickly after their procedure. Other relatively common cases are those of patients who been poorly after a FUT hair transplant technique and patients whose scalp is naturally very tight. In these cases, the FUE technique will make it possible to camouflage the scar by implanting hair and to harvest grafts in a targeted and individual way on a tense scalp.

Some patients request the FUE hair transplant because they have heard that the procedure was minimally invasive or non-surgical. The reality is that the FUE technique, like the FUT that preceded it, is a micro-surgical procedure. The difference and innovation brought by the FUE compared to the previous method lies in the harvesting phase. The FUE method uses very small circular micro-perforations that are spread in the sampling area and leave no visible trace after 48 to 72 hours.


Most of the transplanted hair will fall about three weeks after the transplant. This marks the entry of the transplanted follicles into the resting phase during which they do not produce hair. This is absolutely normal and this resting period varies significantly from one patient to another (it usually lasts 3 to 6 months). On average, patients can expect a regrowth of :

  • 10% 3 months after the transplant.
  • 20% to 30% after 4 to 5 months.
  • 40% to 50% after 6 to 7 months.
  • 60% to 70% after 8 to 9 months.
  • 80% to 90% after 10 to 12 months.
