DHI Hair Transplantation: What Is It?

Direct Hair Implantation, often known as DHI hair transplantation, refers to the direct transplantation of hair follicles. Contrary to traditional FUE, with this technique, grooving is not done prior to hair transplantation; instead, the hair is implanted immediately using specialized needles called implanters. This type of transplantation enables transfer across hairs because it doesn’t call for grooving. As a result, hair transplantation can be done without requiring hair to be clipped.

The primary reason women choose to have this surgery is because it allows them to have hair planted between their hair strands without having to remove their hair. This approach is also known as hair transplantation for women. But in identical circumstances, males might also profit from this hair transplant method.

Phases of DHI Hair Transplantation

The DHI method for hair transplantation has three phases:

  1. Making preparations for a hair transplant
  2. Hair follicle harvesting
  3. Grooving and transplantation of hair follicles

In contrast to other techniques, the DHI approach uses a unique tool called the Choi Implanter to simultaneously open micro hair channels and implant grafts. The Choi Implanter pen is used to perform hair transplants. Hair follicles are gathered, isolated from their surrounding tissue, and then put one at a time into the implanter pen. They are methodically and properly inserted into the implanter. In this approach, the hair transplantation technique produces results that look natural.

The best angles for hair transplantation are 40 to 45 degrees, and the hair follicles are planted in the natural (combing) direction of the hair. The Choi tool is used to conduct transplantation by pressing the hair follicles at the proper angle and direction. During this process, the natural hair is kept. A total of 2 to 6 Choi pens and an average of 15 to 16 sharp Choi tips are used in the process. These pens’ tips can come in a variety of sizes. The size of these tips is determined by the individual’s hair root and hair thickness.

Benefits and Drawbacks of the DHI Method

The DHI hair transplant technique differs from the FUE technique in a number of positive and negative ways.


  • It ensures healthier hair planting and reduces the amount of time hair follicles spend outside of the tissue.
  • The likelihood of hair follicles surviving is increased.
  • The risk of bleeding is as less as feasible due to the reduced incision region.
  • In the DHI procedure, having hair in the transplanting location is a more minor issue. Consequently, it is possible to transplant more readily between the strands of hair in locations where there isn’t total hair loss.
  • After the procedure, a quicker recovery can be seen, allowing the patient to quickly resume their normal daily activities.
  • The DHI method enables hair transplantation without shaving and allows for denser hair implantation in smaller spaces.


  • Both the doctor and the hair transplant team must go through a very extensive training process in order to master this method.
  • When compared to other hair transplantation treatments, it can often be said to be more expensive.
  • The surgeon doing the transplant should be skilled and careful because it is a highly delicate procedure.
  • Due to the narrowness of the transplantation area and the risk of neighboring hair follicles being damaged by the Choi pens used by the specialist, transplanting in a hairy area demands expertise.

Is DHI Hair Transplantation Available to Everyone?

Choi tips are a far more safe way to perform hair transplantation in the modern era thanks to scientific and technological breakthroughs. With these suggestions, hair transplantation results can be effective, dependable, and most importantly natural-looking at expert clinics.

When the Choi pen was first created, it could only be used on people with straight, thick hair, but as advancements have been made through time, its range of applicability has increased. Choi pens can currently be found in sizes ranging from 0.64 mm to 1.0 mm, allowing the DHI process to be applied to many hair types.
