DHI vs. FUE. Which hair transplant method is best? Which one should I go for? These are probably topics that you’ve already come across quite a lot during your Google research on hair transplants. And with such a vast amount of information out there, it’s understandable that things can quickly become confusing. That’s why we’re here to give some clear definitions of both DHI (Direct Hair Implantation) and FUE (Follicular Unit Extraction). We’ll look at what these treatments are, examining their differences, and provide some tips on how you can make a decision about which one is right for you. But before we get into that, let’s take a closer look at what DHI and FUE are and how they work.

What is an FUE hair transplant?

FUE hair transplant surgery has gained in popularity over the last decade. Unlike the classic technique, FUT (or Follicular Unit Transplantation), in which a strip of skin is removed to harvest the grafts, FUE extracts the grafts directly from the scalp. As a consequence, FUE does not leave such visible scarring and ensures natural-looking results.

How It Works

During an FUE hair transplant, groups of 1–4 hair follicles, known commonly as grafts, are manually extracted one at a time and placed into a storage solution. Once the extraction stage is complete, the doctor will open the canals using microblades. These are the holes or slits into which the grafts are implanted. Once the canals have been opened, the doctor can then remove the grafts from the solution and implant them into the recipient area. Following FUE surgery, patients tend to notice the first results appearing around two months after the transplant. More significant growth usually becomes visible after six months, while the full results typically appear 12–18 months after the procedure.

What Is DHI and How Does It Work?

DHI is a relatively new procedure and, similarly to FUE, it leaves no visible scarring and produces natural looking results. While the graft extraction process is similar to FUE, there are a few differences worth noting.

How It Works

To start with, hair follicles are extracted one by one using a specialist tool with a diameter of 1mm or less. The hair follicles are then loaded into an implanter tool, known as a Choi Implanter Pen, and implanted directly into the recipient area. During DHI, the creation of the canals and the implantation happen simultaneously. The Choi Implanter Pen gives the doctor more precision when implanting the hair follicles. This allows them to control the angle, direction, and depth of the newly transplanted hair. Recovery time for DHI is similar to FUE. Results usually appear within a similar timeframe too, with full results typically taking between 12–18 months to appear.

What Is the Difference Between DHI and FUE?

The main difference when it comes to DHI vs. FUE is the way grafts are implanted into the recipient area. During an FUE hair transplant, the canals need to be opened prior to implantation, which then allows the surgeon to manually implant the extracted grafts. DHI on the other hand, makes use of a specialist tool known as a Choi Implanter Pen. This allows the implantation stage to happen right after extraction, without the need to first create the canals for the grafts.

Which One Is Right for Me?

So, now that we have a basic understanding of what these two procedures are, your next question might be, “which one is right for me?” To help us answer this, we asked one of the most renowned hair transplant specialists, Dr. Emrah Cinik, MD, to give us a few pointers on this topic. Dr. Cinik explained that, “DHI is typically recommended for patients who are younger than 35 because in these cases hair loss is not very advanced and success rates are higher.” He also noted that, “DHI is a good option for those who want to lower their hairlines and fill up their temples. The maximum number of grafts we implant with DHI is 4000.” We also asked Dr. Cinik about DHI vs. FUE in terms of surgery success rates. He explained that there’s virtually no difference between the two here, as “both FUE and DHI’s success rate is up to 95%”.
