Therefore, it is necessary to resort to a final and radical solution that addresses this problem: hair transplantation, especially the DHI technique.

Initially, such operations were performed in complex ways with unsatisfactory results and many complications. However, with recent medical developments, hair transplant operations such as the DHI technique have become comparable to natural hair, especially in Turkey. In this article, learn the details of the dhi technique for hair transplantation and for whom it is performed in Turkey.

What is the DHI technique for hair transplantation?

The dhi technique of hair transplantation or what is called Direct Hair Transplant Direct Hair Implantation is a modification and development of the technique of picking (or the so-called fue technique for hair transplantation), wherein the dhi technique, a tiny slice is separated from the hair-giving area and implanted directly in the hair-free area.

The DHI hair transplant technique is characterized by being an alternative method of surgery in which a surgical scalpel is not used at all. A specific device called a Choi pen is used instead. Therefore, this method is also called the Choi pen technique for hair transplantation.

The difference between FUE and DHI hair transplantation

The DHI hair transplantation technique is a development and modernization of the FUE technique, which is still widely used in this field. Therefore, it is necessary to compare the most important differences between these two technologies shown in the following table:

DHI hair transplant FUE hair transplant
Hair follicles are extracted and transplanted at the same time Extracting and transplanting hair follicles is done in two separate steps
No sharp surgical instrument is used Sharp surgical tools are used
There is no need for haircuts Hair must be shaved
The duration of the operation is less The duration of the operation is more
The number of transplanted bulbs is about 80-90 bulbs per square centimeter The number of implanted bulbs is about 60 bulbs per square centimeter
Neither blood pressure nor blood sugar affects the procedure Blood pressure and blood sugar affect the procedure
The tools used in the process are Choi pens, which are used to harvest the follicles and plant them directly The tool used is a micromotor, which is used to soften the follicles before extracting them

  • Wounds and skin burns of all kinds, mainly if they include a large scalp area.

  • The surgeon then performs local anesthesia of the donor and recipient areas in the scalp with xylocaine 2% with adrenaline to prolong the effect of the anesthetic used.
  • Determine the locations of the slices that will be removed from the donor area (usually from the back of the scalp or the sides) and the places of implantation in the bald or recipient area, in addition to making tiny holes that represent the receiving areas, using an excellent needle.
  • After that, the surgeon begins to remove a microchip with a diameter of about 0.5 mm using a Choi pen and implant it directly in the previously prepared recipient sites (no surgical scalpel is used to open the skin), and the extraction and implantation process is repeated until the entire bald area is covered.

Frequently Asked Questions

The dhi hair transplantation technique or direct hair transplantation is a modern technique that aims to perform hair transplantation with high accuracy and low risks, in which choi pens (a pen-like instrument with a hollow needle on one end) are used without resorting to any surgical instrument such as a scalpel.

There are many techniques used today in hair transplantation, each with its pros and cons, and these techniques are:

  • Chip technology, or what is known as FUT technology.
  • Extraction technique or what is known as FUE technique.
  • The Choi hair transplantation technique, or what is known as the DHI technique, is a modified technique of the FUE technique.

The tools used in the fue technique differ from the dhi technique, where a sharp tool called a micromotor is used to extract hair follicles from the hair-giving area in the fue technique, while in the dhi technique, a choi pen is used for hair transplantation.

In the fue technique, a series of channels are cut in the scalp manually before inserting the hair follicles, while such a procedure is not performed in the dhi approach, where the incisions are made and the bristles are implanted at the same time.

The transplanted hair can fall out after the dhi hair transplantation process in about 2-3 weeks. Then the hair begins to grow slowly, so the total result of the transplantation may take approximately a year after the procedure. Still, the effect of the operation often lasts for life.

The appropriate age for hair transplantation is 25 years and above due to the possibility of baldness if hair falls before this age, in addition to the impossibility of predicting the natural diameter of the hair.

Although the side effects of hair transplantation are almost non-existent, they may occur in a small percentage of some patients, the most important of which are:

  • Adverse reaction to local anesthesia.
  • infection.
  • hair loss shock
  • Swelling of the scalp.
  • lightheadedness or dizziness;
  • Folliculitis.

It is certainly possible to perform a hair transplant twice using the DHI technique in order to increase the density of the hair transplanted the first time or if the first result was not satisfactory for the patient, but the duration of the second operation is less than the first.

It is possible for us to have a failed hair transplant using the DHI technique if the doctor who performs it is incompetent or if there is a disease that affects the result of the hair transplant.

You can have quiet sex after about two weeks of hair transplantation, as the hair follicles have settled well.

The pain after hair transplantation lasts about two weeks, but it can be controlled with some painkillers or ice packs.

The cost of hair transplantation using dhi technology (direct hair transplantation) in Turkey starts from 1200 USD, but the price varies according to the area to be transplanted.
