How is DHI Method hair transplant performed?

The grafts (elements of the hair tissue of the head with hair follicles, 1 graft includes 1 to 4 follicles) are taken from donor areas (lateral and occipital zones).

The extracted grafts are first placed with a special liquid of a certain temperature, which ensures their good engraftment after transplantation.

Then, using the same tool, the hair follicle is implanted in the receiving area, according to the direction of hair growth, at an angle of 40-45 degrees, to a certain depth. Hair implantation is performed under local anesthesia, without preliminary incisions and punctures of the skin.

How long does the healing process after a hair transplant take?

Micro-wounds in the withdrawal zone and in the setting zone resemble punctures from a medical injection, which heal without a trace in 3-5 days. During the first 6 months, the transplanted hair falls out several times and grows again. The patient will be able to see the final result approximately 7-8 months after transplantation.

After the procedure itself, the patient can return to work the next day, as this procedure is minimally traumatic and does not require dressing.

How many grafts can be transplanted in one procedure? How long does a hair transplant take?

At any stages of alopecia, transplantation is carried out painlessly and comfortably, as an outpatient, most often – in one go it takes 5 to 9 hours. If necessary (large areas of baldness), performed twice. Up to 5,000 grafts can be implanted at a time.

Advantages of DHI Hair Transplant

  • The main advantage of DHI is minimal trauma and aesthetic effect and a high % of excellent growth of transplanted hair.
  • The DHI tool enables the hair tissue to be placed well, thus there is a low risk of scars.
  • The DHI hair transplant operation does not require any incision.
  • The DHI device controls the depth, angle and direction of the hair follicles implanted.
  • DHI hair transplant is a safe operation with a low risk of complications.



Transplantation is contraindicated in diabetes mellitus, arterial hypotension, cancer, some diseases of the scalp, specific mental disorders (trichotillomania, dysmorphophobia);

Also, hair transplantation is not recommended for patients under 17 years of age, when the hormonal background is not yet stable. And for those over 70, when the recovery processes in the body slow down, and graft survival cannot be guaranteed.


What tests are required for a hair transplant procedure?

Immediately prior to the hair transplant procedure at Medworld, a patient is sampled for clinical analysis. The doctor collects an anamnesis and, after receiving necessary results, proceeds to the operation.


Are there any risks during surgery?

The success of a DHI hair transplant depends on the professionalism of the doctor and his team. Medworld doctors are transplant surgeons, professionals with many years of experience and impeccable practice, who directly supervise the entire procedure from start to finish, which is extremely important. Hair transplantation procedure affects only the surface layers of the skin, so do not worry about risk or complications. Referring to our many years of experience, we can say that the likelihood of unforeseen complications is unlikely.


What is the difference between DHI and FUE?

In contrast to the FUE method, the grafts are taken in DHI and implanted simultaneously, thus reducing the time spent by the hair follicles outside the human body, which ensures a more successful result. The DHI method allows hair transplantation without shaving the head, and also allows you to get a denser fit, and as a result, thicker hair. The downside is that the DHI transplant takes longer, the grafts are transplanted one at a time, which requires more accuracy and care.
