In traditional hair transplantation, a strip of skin is cut from the back of the head and transplanted in the recipient site, leaving a long scar in the donor area. This strip is cut into micro or single graft transplants and then replaced. Other methods manually remove the follicles one by one. Of all these methods, the most advanced is the one practiced by Hair Science Institute. Because of the dimensions of the needle, the experience of the employees, and the precision of the procedure, neither the donor area nor the recipient area are damaged, which allows us to achieve natural results.

With FUE (Follicular Unit Extraction), the entire follicle is removed with a needle 0.75 to 1.0 millimetres in diameter (0.45-0.8 mm²). This size needle means a considerable chance of scarring, and the regrowth of the hairs removed is minimal.

Who is it for?

Yes, in theory anyone can be treated. You can meet with one of our doctors for a free, non-binding consultation to discuss what this technique can mean for you. In certain situations we do not recommend hair transplantation.

Yes, our method is excellently suited for the treatment of scars. Our employees have extensive experience in this area.

Yes, our method is also suitable for treating burns. We work closely together with various burn centers in The Netherlands and Belgium.

Yes, our method is also suitable for treating eyebrows, beards, and moustaches. Many treatments are performed in these areas every year.

Often, afro-textured hair cannot be treated because the curled structure of the hair continues into the hair follicle. Because of the subcutaneous curl, the hair stem cells cannot be removed with enough precision.

This should not generally pose a problem, although if the donor area is severely damaged we may be limited in the number of grafts we can obtain per treatment During a free consultation one of our doctors can evaluate your situation.

Personal consultation

Of course, this depends on the size of the area to be treated. We will give you an exact indication during a free, non-binding consultation. We can say from experience that one treatment is generally sufficient for treating minor male pattern baldness, retreating hairline or small bald patch.

At present, the price per treatment day depends on the number of grafts transplanted. Every graft can produce 1 to 4 hairs. The average number of hairs produced per graft is 2.5, so the number of hairs after 1,200 to 1,400 grafts is approximately 3,500. However, the number of grafts we can or should remove depends on the quality of the skin and hair follicles, the size of the donor area, the presence of scars and, of course, the client’s needs.

Both the consultation and the treatment are conducted by certified doctors and nursing staff.

Preparation

Should hair be cut before for treatment or grown properly?
If you want the donor area to be covered after the treatment, we recommend that you grow your hair on the back and sides to a length of at least 8 centimetres. The best results are obtained by shaving the entire head, although for obvious, aesthetic reasons, this is not generally done on women.

The treatment

A single treatment will, on average, take a whole day, from 7:30 AM to approximately 5:00 PM. In the morning, you will be lying face down as the grafts are removed. Lunch will be provided. After lunch, we make the holes in the receptor area and then implant the grafts. In the afternoon, you will be sitting upright. Throughout the treatment you will be able to watch films and take breaks.

No, you will not feel anything during the procedure. Of course, a local anesthetic is administered in the treatment area. Drs. Gho has developed a new, virtually painless anesthetic especially for this technique.

The number of grafts required depends on your degree of baldness and your wishes. Additionally, the number of hairs that can be transplanted depends on the size of the donor area and any scars present. Propensity for bleeding, hair colour, and skin structure are also factors. In a normal procedure, some 3,000 grafts (average 2.5 hairs per graft) can be transplanted in a treatment day.

On a given treatment day, 30-35 grafts per cm² can be placed (in a completely bald area). In a subsequent session, this density can be increased, up to a maximum of approximately 50 grafts per cm².

Results

The wounds created after a HSI treatment session are so minuscule, they require virtually no recovery process. After four days, you will be able to wash your hair as normal, and we know from our prior treatments that there are generally no visible effects at that point. Within seven to ten days , all visible signs of the treatment will have vanished.

Because we use needles no larger than 0.6 millimetres in diameter, there will be no visible scars and you will be able to style your hair in any way you like.

In theory, all transplanted hairs will ‘take’. In practice, the grafts are the most vulnerable in the first few days after treatment, and you may lose a few. You can minimize this number by following our instructions.

We will assess the final result in the clinic nine months after treatment. The transplanted grafts will start growing immediately after treatment; however, we can’t predict how many grafts this involves. The transplanted hairs may also fall out two to eight weeks after treatment. The transplanted tissue is strongly anchored in the skin and will produce new hair. This takes time, which is why we wait nine months to determine whether all of the transplanted hairs have started growing.

The transplanted hairs come from a donor area that is not susceptible to hormone-related hair loss. These qualities are also maintained at the new site, which means the hair will not fall out. The only exception to this is a hair condition like alopecia areata. Should someone require chemotherapy, this will have a negative impact on all of the hair on the head. Fortunately, we know from experience that the hair recovers and regrows – including the transplanted hair.

The remaining hair in a transplanted area are subject to the ongoing process of hormone-dependent hair loss. As a result, you may notice thinning in the transplant area. This is not caused by the hair falling out.

After the treatment

You can shampoo and blow-dry your hair four days after the procedure, and colour and perm your hair again a month after treatment. You can also colour your hair up to one day before the treatment.

Although you can resume your daily activities immediately after treatment, we recommend that you avoid heavy physical exertion in the first two weeks after treatment.

You can fly immediately after the treatment. To allow the tiny wounds caused by the procedure to heal, we recommend that you do not spend time in the sun until all the small scabs are gone.

Yes. Yes. In the course of the treatment you will not be administered any medication that would impair your ability to drive. After a treatment day, you will be able to drive yourself home.
