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
- 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.
