The HASCI method

A hair stem cell transplant, also known as the HASCI method, does not remove the entire hair follicle. Instead, several hair stem cells are left in the donor area to stimulate regrowth.
  • Multiple transplants can be performed in a single donor area
  • No scarring
  • Painless treatment

As only a portion of the hair follicle and the stem cells it contains is removed, the remaining and transplanted stem cells stimulate new hair growth in a matter of weeks. The remaining and transplanted hair stem cells generate the same quality hair as the existing hairs. The final result can be seen after a full hair growth cycle of nine months.

How does hair stem cell transplantation work?

Studies carried out by doctor and researcher Coen Gho found that several new hairs can be produced using only part of the hair stem cells (instead of the entire follicle). This results in new hair growth in both the donor area and the receptor area. The HASCI method cleverly utilizes natural stem cells paired with a specially-developed medium that guarantees the viability of the grafts and stimulates further growth in the stem cells. Both components are essential to achieving the desired results and is what makes the HASCI method so unique. A natural hairline can be created using smaller grafts than the ones used in other techniques.

There are more hairtransplantation techniques

Various hair transplant techniques are available, each with their own advantages and disadvantages.

 

Follicular Unit Transplantation (FUT)

A well-known and long-standing method of hair transplantation is the strip method, otherwise known as follicular unit transplantation or FUT. With this technique, a strip of skin and hair is removed from the back of the head, sectioned into grafts, and transplanted in the receptor area.

  • Excessive scarring
  • Painful
  • The hair in the donor area is completely sacrificed for the transplantations, making it impossible to reuse

This method results in excessive scarring in the both donor area and the receptor area because square grafts are transplanted into round holes, causing scar tissue to form. These obvious and unattractive scars are the biggest disadvantage of this method, which also happens to be the most painful.

This technique also results in hair retention of just 70 to 95%, as some of the grafts inevitably fall out or are unsuitable for transplantation. This means hair loss of 5 to 30%. Of course, the end result differs per person.

Follicular Unit Extraction (FUE)

A second, more modern technique is Follicular Unit Extraction (FUE). This technique extracts entire hair follicles from the donor area one by one and transplants them in the receptor area. FUE results in dozens of small, round scars in the donor area.

  • Excessive visible scarring
  • Painful technique
  • No regrowth

A major disadvantage of the FUT and FUE transplant methods is that the extracted follicles are removed entirely, creating an even smaller donor area. Hair transplant methods that use these techniques have a limited number of donor follicles as no regrowth occurs in the donor area after transplantation.

The FUE method results in hair retention of 90 to 96%, as some of the grafts inevitably fall out or are unsuitable for transplantation. This means hair loss of 5 to 10%. Moreover, neither of these methods allow for short hairstyles due to clearly visible scarring.

Hair Stem Cell Transplantation

More hair after treatment

Each hair follicle consists of different areas that contain hair stem cells. The scientific studies conducted by Coen Gho found that there was no need to extract the entire hair follicle; just a small part of the follicle is capable of producing new hairs. Under ideal circumstances, this technique can be used to create two follicles from a single follicle to generate hair growth.

As a result, the donor area can be used for future transplants.This method uses a hollow needle of just 0.5 to 0.6 mm in diameter. The hair shaft is used as a guide to remove part of the follicle. By following the hair shaft, the needle automatically reaches the correct location to remove a few stem cells. This makes it possible to extract a small portion of the follicle, even if the shape is not ideal. The result is a well-preserved donor area that can be used to harvest new hair follicles for future treatments.

An overview of the HASCI method

  1. It starts with a local anaesthetic. HASCI uses its own unique anaesthesia method that is much less painful than traditional methods
  2. This makes the treatment itself entirely painless
  3. And thanks to the exceptionally small needles, there's no post-operative pain either
  4. The end result is virtually complete regrowth in both the donor and receptor areas
  5. Full healing of the donor area within two days
  6. A very natural result
  7. Full healing of the receptor area within five to seven days
  8. Suitable for facial area treatments
  9. Suitable for treatment of scar tissue (e.g. burn wounds)
  10. Multiple treatments are possible thanks to the full recovery of the hair follicles in the donor area

An overview of the differences between the three methods

The table below shows the differences at a glance.

The differences Fut (strip) FUE HASCI
Sedatives before treatment usually usually no
Pain during procedure some no no
Stitches yes no no
Scarring in donor area yes, one large scar yes, white dots no
Loss of donor area yes yes limited
Reusability of donor area limited limited good
Pain after treatment yes limited little
Swelling after treatment yes yes rarely
Recovery period 14 days 10 days 5-7 days
Maximum number of grafts per treatment 2500-3000 2000 3000
Body hair transplant possible no limited yes
Treatment of scars and burn wounds very limited acceptable good
Treatment of eyebrows, moustache and beard very limited acceptable good
Results 70-90% 80-95% 100%

Body hair

The HASCI method is one of the few techniques that allows for body hair transplantation. Body hair transplantation is a technique in which hair from elsewhere on the body (for example, the lower leg) is used as the donor area. This form of treatment may be useful if the quality of the skin and/or hair on the back of the head is poor or if there is no viable hair due to burn wounds, for example.

It's also useful if the donor area (the back of the head in most cases) doesn't contain the desired hair type. Curly hair, for example, isn't suitable for an eyebrow restoration. In this case, straight hair from another part of the body would be used instead.

The fact that nearly all body hair can be used as donor hair highlights the potential of this technique. It should be noted, however, that the transplanted hair will retain the qualities of the area from which it was harvested. Body hair has different qualities that must be taken into account during the transplant process. The resting phase for body hair can be extremely long (i.e. years), which means it could take a long time to see new hair growth in the receptor area.

Scars and burn wounds

Doctor/researcher Coen Gho has been closely involved in the development of new medication and treatment methods for burn victims since the early 1990s. The results of his research led to the development of the HASCI method, which has been of invaluable importance to the physical and emotional recovery of many burn victims over the years.

Afro-textured hair

T

he HASCI method can be used on almost any hair type. Afro-textured hair may be an exception. This is because the curly structure of the hair continues subcutaneously into the hair follicle. For afro-textured hair, it is difficult for the needle to follow the curly structure of the hair shaft and the subcutaneous hair follicle. As a result, it's impossible to accurately determine whether sufficient stem cells have been removed and what the results of the treatment will be. The likelihood that the HASCI method won't work is higher in patients who have two parents with afro-textured hair.

As all hair is different, we recommend contacting one of our clinics to discuss the options. With a few photographs of the different areas of your head we can determine whether treatment is possible. A trial treatment is also possible and can give you a better understanding of the options.

Hair Stem Cell Transplantation: a patented and sophisticated technique

Doctor/researcher Coen Gho has conducted fundamental research on hair transplantation since 1996. His studies have found that different parts of the hair follicle contain stem cells that can stimulate hair growth. These studies formed the basis of the hair multiplication techniques used by Hair Science Institute, such as hair stem cell transplantation.

The HASCI method is a hair stem cell transplant method that utilizes the potential of stem cells. This technique was developed by Hair Science Institute and is used worldwide in our clinics in Amsterdam, Maastricht, Cap d'Antibes, London, and Jakarta.

A hair stem cell transplant using the HASCI method is only possible in one of the certified Hair Science Institute clinics, where the technicians and doctors were trained by the Hair Science Academy.
