What Is Choi Pen In Hair Transplantation?

Choi Pen, 1992 yılında Güney Kore’deki Kyongpook Ulusal Üniversitesinde icat edildi. Hassas ince uçlara sahip olan bu kalem sayesinde, saç ekimi işlemleri hiç olmadığı kadar kolaylaştı.

DHI hair transplantation is a technique born from the FUE technique. The biggest advantage of this technique is this pen. So, in this technique, Choi pen is used. In fact, the reason why it is called a pen is that its shape resembles a pen.

The tip of the pen has a needle with a diameter of 0.5 mm - 1.5 mm. There is a tiny motor called a micromotor behind the needle.

The pen has two functions, that is, areas of use. Its first function is to remove hair from the donor area. Its second function is hair transplantation. Thanks to the many different functions of the pen, both functions are fulfilled successfully.

After the grafts are removed with the pen, the tip of the pen is changed. Grafts are placed into the needle, which is connected to the piston through a tube, and transplantation is performed.

How to Perform Hair Transplantation with Choi Pen?

This pen is used in the DHI hair transplantation method. Hair follicles are taken from the donor area with the help of a pen. Thanks to the Choi pen, unlike other methods, there is no need to open channels to remove hair follicles.

With the same pen, both hair follicles are removed and hair follicles are opened to the area to be transplanted. Choi pen has a cylindrical and sharp tip. In other words, the structure of the needle is similar to the structure of the hair follicle. In this way, it can easily move along the channels of the hair follicles. The needle goes down to the hair root and allows the graft to be placed in one go.


How to Use Choi Pen?

In the DHI hair transplantation method, Choi pen is performed in the following stages:

  • Grafts taken from the donor area are kept in a special solution for a while and then placed into the pen one by one.
  • The surgeon performing the operation applies the hair follicles to the hairless area at an angle of 40-45 degrees, which is the most appropriate angle. The process takes a long time because it is done separately for each hair follicle.
  • After the placement process is completed according to the direction of hair growth, the patient is left to wait for a while. Then, bandaging is done and the process is completed.

What are the Advantages and Disadvantages of the Choi Pen Method?

The advantages of the DHI Choi Pen method are as follows:

  • Hair follicles taken from the donor area are more likely to survive.
  • Fewer incisions are made in the area where transplantation will be performed. Thus, the recovery time is shorter.
  • Since the graft is taken from the donor area with the help of a pen, very small wounds occur and these wounds heal in a short time.
  • This method is applied without shaving.


  • The cost of the operation performed with a pen is higher than other methods.
  • It takes longer to complete than other methods. In some cases, one session is not enough. In other words, the process continues on other days according to the planning made.
  • The surgeon who will perform the transplant needs to be more careful. If the surgeon who will perform the operation is not experienced, he may damage other hair follicles with the Choi Pen.

Because of the hair’s anatomical variations, we used to have difficulties in extracting them during the hair transplant surgery. Fortunately, all these aspects are left behind. Thanks to advancements in an FUE (Follicular Unit Extraction/Excision), hair transplant for those with afro hair has become more accessible, with better results and higher survival rates.
