DHI Hair Transplantation

DHI, or “Direct Hair Implantation,” is not a new technique but has recently gained renewed interest. Individuals experiencing hair loss often struggle to choose between DHI and Micro-FUE. Before selecting a method, it is essential to understand your expectations and determine which technique suits you best. This involves various technical aspects such as experience, cost-effectiveness analysis, and more.

Before deciding on a hair transplant technique, we highly recommend undergoing an analysis and selecting the most suitable method in consultation with your doctor.

How Is DHI Hair Transplantation Performed?

In this technique, grafts are extracted from the donor area at the back of the head, just like in Micro-FUE. The grafts are kept outside the body for a minimal duration and implanted immediately. This ensures that the transplanted hair remains healthier and stronger. Unlike other techniques, channels are not opened in advance, and hair follicles are implanted directly using special implanter pens. Since no pre-prepared channels are required, the procedure saves time, and the extracted follicles are transplanted right away.

As a result, the transplanted hair adapts quickly and remains healthy. Compared to the Micro-FUE method, a lower number of grafts can be transplanted in a single session. The procedure is virtually painless, and since fewer grafts are implanted with less trauma, the recovery process may be faster compared to traditional FUE and FUT techniques.

Differences Between DHI and FUE Hair Transplantation

In the FUE technique, extracted grafts are not immediately implanted. Instead, they undergo a special preparation and healing process before transplantation. Micro-surgical blades are used to create channels in the recipient area, and then the transplantation is performed.

In contrast, the DHI technique involves the use of implanter pens, known as Choi pens, which allow the grafts to be implanted immediately after extraction. With the Choi implanter, both the channel opening and implantation occur simultaneously. During transplantation, factors such as the direction and density of the hair are carefully considered.

Compared to FUE, the DHI technique is more labor-intensive and usually takes longer.

Before Choosing the DHI Method!

Deciding between FUE and DHI should be left to your hair restoration specialist. While promotional materials highlight the advantages of each technique, your doctor—who performs the procedure—will consider various factors when selecting the surgical approach. Therefore, choosing the most appropriate method should be a decision made in consultation with your doctor.

Advantages of the DHI Technique:

  • Allows hair transplantation without shaving the existing hair
  • More commonly preferred for hair density enhancement
  • Hair follicles remain in an isolated environment for a shorter period
  • Enables a higher number of grafts per cm²
  • Causes less trauma

Disadvantages of the DHI Technique:

  • Higher incidence of rebound (grafts moving outward from the skin) during transplantation
  • May require 2-3 sessions to cover large areas
  • Limited number of grafts can be implanted in a single session
  • Takes longer compared to the FUE technique
  • More expensive than the FUE method
  • Hair follicles may be subjected to greater pressure trauma during implantation
