Everyone wants to have beautiful and healthy hair

Do you still dream of having beautiful, full and natural hair? The Hair Stem Cell Transplantation (HST) method can turn this dream into reality. HST is a patented and revolutionary method of transplantation based on decades of hair stem cell research. HST is perfect for anyone who wants to feel good with thick, beautiful hair – men, women, young or old.

If you are looking for the best hair transplant possible, HST has proven to be more effective than any other technique and leaves you with a natural result that lasts for a lifetime.

Dr. Coen Gho

The driving force behind the Hair Stem Cell Clinic is Dr. Coen Gho. His commitment to improving patients’ lives and innate passion for science formed the basis for the development of the hair stem cell transplantation technique.
When Gho was working with young burn patients in his early years as a doctor and researcher, he saw that hair transplants were painful treatments that often left large scars. He believed that this had to change.

Gho realised that the key to making a difference could be found in hair stem cells. He managed to get funding for stem cell research from several large companies who believed that the inspired young doctor could make a change. This has led to years of intensive research, which have produced an innovative medium that stimulates the tissue to renew its cells. This was a major breakthrough in his research and an important basis for the subsequent transplantation of hair stem cells. As inventor and developer, Gho obtained a patent for this method.

His drive to improve hair transplantation techniques only increased. Driven by his research, Gho wanted to realise his dream: to be able – in the future – to obtain a thousand hair follicles from one hair. To do this, he contacted Professor Dr. Martino Neumann, an international authority in the fields of dermatology, phlebology and oncology. He was sceptical about Gho’s ideas but took him under his wing to conduct the research.

Transplantation technique of partial longitudinal follicular units (PL-FUT), under the simpler name Hair Stem Cell Transplantation (HST). Dr Coen Gho, a physician and researcher, has conducted research with academic universities and hospitals around the world and is affiliated with the International Society of Burn Injuries (ISBI).

Gho also collaborates with the Red Cross Hospital Burns Centre Beverwijk and the European TissueRepair Society. He has developed various new therapies and methods of treating scalp burns. With an endless drive and his vast experience in hair, stem cells and tissue engineering he works tirelessly to refine the HST technique and make treatments even more suitable for patients.

The Hair Stem Cell miracle

Hair Stem Cell transplantation harnesses the power of nature by tapping into the regenerative capacity of human stem cells. The special feature of this innovative technique is that only a small part of the hair follicle, rather than the entire follicle, is harvested from the donor area. This small portion of tissue contains enough stem cells to grow new hair in the receptor area.
This is a small miracle: this regenerative capacity results in more hair from a single graft (hair follicle). The new grafts (hair follicles) are closely packed together, which creates a high hair density and a natural-looking aesthetic line. A special patented preservation solution stimulates growth and increases the vitality of the grafts, making them more effective. This integrated approach is the basis of our sophisticated hair transplantation method, which increases hair growth in both the receptor and donor areas.

The method is extremely effective, with minimal scarring, high hair density and a completely natural end result.

The day of the treatment

Hair Stem Cell Transplantation usually takes place within one day of treatment. We start by taking photographs and anaesthetising the area to be treated. This is followed by the harvesting of the grafts. You won’t feel anything, all we ask for is your patience. Stay alert throughout the day and you will not be under the influence of any sedatives. In the meantime you can make a phone call or stretch your legs.
The doctor will then mark the receptor area. Afterwards we will offer you a lunch of your choice. In the afternoon, after applying the anaesthetic, the doctor prepares the receptor area, after which the technician applies the grafts in their new position.

Once the treatment has been completed, the doctor will perform a full check-up and take some photographs. You will be given instructions and everything you need for aftercare.

Follow-up/contact times are set at one day, one week and one month after treatment to see how it is going. You can always contact us between these time intervals.

Is the treatment painful?

HST is a safe medical-cosmetic treatment that causes little or no discomfort. Our treatments leave no scars and the scalp generally recovers quickly. The treatment is performed under local anaesthesia and you will not feel anything during the procedure.

You can go home immediately after the treatment. The skin will recover within a few days of the procedure. We also give you tips and advice to ensure optimal recovery and the best end result. If you have any doubts about the healing process or side effects, you can contact the Clinic’s specialists for a quick consultation.

Is the end result permanent?

The results of an HST are permanent. Transplanted hair follicles continue to produce hair for the rest of your life. It is the most effective treatment for making hair denser and giving it more volume. Microscopic grafts to ensure a high-density, natural-looking implant.

The results are not immediately visible, but take time to manifest themselves. Implanted hair follicles need a period of time to become established, which differs from person to person. Transplanted hair follicles start growing new hair 3-4 months after treatment. The final result is visible between nine and twelve months on average.

Feel like home

Hair Stem Cell clinics operate to the highest medical standards. Here you can always count on the best possible competence and professionalism. But we also want you to feel at home and able to relax. That is why we do our best to make you feel comfortable. From the first appointment to the final check-up, we make sure you have everything you need and more.

During the treatment, you are entrusted to the care of our dedicated specialists. You will be supported by a team of experts who will organise everything: a delicious lunch, a wonderful four-star hotel, taxi services, relaxation and everything you need to make your treatment a pleasant experience.

The costs of this treatment are mainly determined by the number of grafts that are transplanted. If your baldness is the result of an illness, accident or burn injury, (part of) the costs may be covered by your health insurance. We will be happy to inform you further about this. Whatever your situation, we will always provide you with a clear quote before the procedure that shows a 100% transparent cost calculation.

Who is it suitable for?

What is hair loss and what causes it?

Everyone loses their hair every day, it’s a completely natural thing. Increased loss occurs in some places on the scalp when hair falls out faster than it can grow. If the follicles shrink, the hair cannot be produced, it dies and can no longer grow back. Ciò porta come conseguenza a capelli sottili e indeboliti e a zone più o meno estese di calvizie.

Generally, there are three causes of baldness in men and women:

  • aging;
  • the influence of hormones;
  • hereditary baldness (androgenetic alopecia).
Is hair stem cell transplantation the right solution for me?

There are a number of factors that come into play. The Hair stem cell transplantation method might be suitable for you if:

  • you have been suffering from hair loss for quite a long time and a bald spot (no hair) has developed;
  • you have enough donor hair and good quality;
  • you are in good health for the treatment;
  • the hairline has receded as a result of, for example, an operation;
  • you have lost your hair due to injuries, such as burns.

Getting the right diagnosis is essential. In a free, no-obligation consultation, our doctors and technicians will take the time to discuss your wishes and expectations with you, so that we know exactly what we can do to solve your problem.

Can anyone be treated with the HST method?

In principle, anyone suffering from hair loss or hair loss can be treated. But you can find out more about whether this approach is right for you with one of our doctors in a free, no-obligation consultation. In some situations, a hair transplant is not advisable, e.g. you may be too young.

Can scarred areas be treated with the HST method?

A characteristic of scar tissue is that hair growth on it never recovers. But thanks to the HST method, hair growth can be restored on scars, even if the donor area is limited. Our staff can offer you expert advice on this issue.

Is the HST method also suitable for treating burns?

For more than 28 years, Dr. Coen Gho, a physician and researcher, has been closely involved in the development of new medical and therapeutic methods for people with burn scars. The results of these studies led to the creation of the HST method, which has been a crucial development for many people in recent years in terms of physical and mental recovery.

We collaborate with various burn centres in the Netherlands, Belgium and Germany.

Can the eyebrows be treated with the HST method?

With an eyebrow transplant, the eyebrows are thickened or restored. The HST method uses precision instruments and requires very little recovery time; the eyebrows heal very quickly. The treatment is carried out in a very natural way and gives excellent results.

Can the HST method be useful for thickening the beard and mustache?

Hair Stem Cell Transplantation is a good solution for filling in places without a beard. The HST method is extremely suitable for a beard transplant, no scars are left in evidence, making this technique much more suitable than conventional hair transplant methods.

Why you cannot treat hair with "afro" structure in most cases

in most cases for hair type “afro” treatment is not possible. This is because hair with an afro structure also curls under the skin. In this case, the effectiveness of the HST method varies from person to person. To find out what options are available, please contact us to discuss your personal situation.

We recommend that you discuss this with one of our doctors.

This should not be a problem. However, it depends on the condition of the donor area. The number of grafts can be limited if the area is too damaged. We recommend that you discuss this with one of our doctors.

I am not satisfied with the transplant performed with another clinic. Can you solve the problem? Can you solve the problem?

Personal Consultations

Is the personal consultation free?

The consultation is not free but the cost will then be deducted from the actual intervention if the customer decides to carry it out.

Who carries out the consultation and who does the intervention?

Both consultation and treatment are conducted by a certified doctor and technician. Both the technician and the doctor carrying out the consultation will perform the treatment.

What does the consultation consist of?

Advice can be very useful for both you and us. You will discover the technique, receive personal advice and have the opportunity to ask questions. Together with the doctor, you can discuss your options, wishes and expectations in detail. An individual treatment plan will then be agreed together.

How many treatments do i need?

Of course, this depends on the size of the area to be treated. One of our doctors can assess your situation in a free, no-obligation consultation. In our experience, one treatment is usually sufficient for mild hair loss at the temples or hairline or a small bald patch.

Does my health insurance cover hair transplant?

In general, health insurance does not cover hair transplants. However, in some cases, our treatments may be covered by health insurance under the terms of the policy. This is usually the case when treatment is medically necessary or in the presence of severe psychological distress. For example, scars and burns as a result of an accident and/or medical procedure.

How much does a transplant cost?

The price will be based on the complexity of removing the grafts and the number of grafts. The number of grafts we can remove varies depending on the quality of the skin and hair follicles, the size of the donor area, the presence of scars and the client’s wishes, of course. An indication can be found in the menu section “Prices”.


Do I need to shave my hair or let it grow before treatment?

If you want the donor area to be covered after treatment, it is recommended that the hair grow on the back of the head and sideways to a length of at least 8cm. However, if your hair is shaved, more grafts could be pulled out, which would produce the best results. Of course, this last possibility is rarely practiced in women for aesthetic reasons, unless it is expressly requested.

Can i color my hair?

You can colour your hair up to one day before the treatment.

The treatment

How long does the treatment last and what does it consist of?

On average, a single treatment lasts a whole day, from around 7.30 to 17.00. In the morning, you will be lying face down while the grafts are removed from the donor area. Then there will be a short break and you will be invited to have lunch with us. After lunch, we will drill the holes in the recipient area and then implant the grafts. In the afternoon, we will “get you back on your feet”. During the treatment, you will be able to watch movies and ask for breaks.

Is the treatment painful?

Thanks to the new technique developed by Dr Coen Gho, you will experience virtually no pain with the HST method. Of course, a local anaesthetic will be applied to the treatment area.

How many follicles can be transplanted with one treatment?

In a normal procedure, we can transplant up to 2,000 follicular unit grafts in one treatment day. One graft contains up to three follicular units. However, the number of grafts required depends on your degree of baldness and your wishes. In addition, the number of follicles that can be transplanted depends on the size of the donor area and any scars present.

How many grafts can be made per cm²?

On one treatment day, 30-35 grafts per cm². In a subsequent session, this density can be increased to a maximum of about 50 grafts per cm².


How long are the signs of the treatment visible?

The wounds created after an HST treatment session are so tiny that they require virtually no recovery process. After a certain number of days, almost nothing is more visible. Within a week, all visible signs of the treatment will have vanished. Within a week, all visible signs of treatment will have faded.

Will any scars remain after the treatment?

As we work with needles up to 0.6 mm in diameter, no scars will be visible. This means that you can have any hairstyle you want in the future.

How many grafts will "survive"

In theory, you should be able to keep all the transplanted follicles. However, grafts are more vulnerable in the first days after treatment and some may be lost. You can minimise the loss by following our instructions.

What can i do if i am not satisfied with the result?

We take our treatment very seriously and are only satisfied if we achieve the best results. Our customers’ satisfaction is important and we do our best to make sure they are happy. Despite our care and best efforts, you may still not be satisfied. We will always acquire any complaints and do everything possible to find a solution. All you have to do is contact us and (in the contact section) and forward your complaint as clearly as possible, specifying which treatment it relates to. We will contact you as soon as possible and do our best to resolve the situation satisfactorily.

After the treatment

When will I be able to wash, dry, color or style my new hair?

Washing with shampoo and drying: four days after the treatment.
Coloring and permanent: one month after the treatment.

Can I go back to work and pursue my sporting activities immediately after the transplant?

Sport or heavy physical exertion is not recommended in the first two weeks after treatment. However, you can go straight back to your daily work.

Can I take the airplane or leave immediately after the treatment?

You can fly immediately after the treatment. But to allow the wounds to heal, it is not advisable to expose oneself to the sun until all the scabs on the skin have disappeared.

Can I drive immediately after the treatment?

Yes. During the course of treatment, no medication will be administered that may impair your ability to drive. This means that you can drive home immediately after the treatment.
