DHI-Direct Hair Implantation
DHI Hair Transplant is the process of extracting hair follicles from the donor area via utilizing a micro motor and then transplanting them into the desired areas using a pen-like device that contains a hollow needle. The first thing that comes into mind when we say DHI is usually the FUE method, but there are actually some differences between the 2 techniques.
Similar to FUE, Direct Hair Implantation is a method used for hair transplants to give patients with balding or thinning hair a naturally thicker appearance. It also does not require the removal of a donor strip of scalp to extract individual follicles and it does not leaves scarring as well. However, unlike its predecessor DHI technique enables the hair transplant to be performed without shaving the head. Making it the best option for woman and man with long hair.
Before the extraction of the follicles begins, the only donor section of scalp is shaved. Just like with FUE – the donor area is cleansed and anesthetized with a local anesthetic. Instead of making slits before implantation, the surgeon uses Choi pen, a disposable devise that looks like a pen that has an accurate head. The extracted grafts are inserted into the Choi pen one-by-one by the medical staff, then implanted into the desired areas of the scalp. It is easier to transplant between hair strands if the patient has healthy areas on his/her scalp. In addition, DHI allows us to achieve higher density of hair, especially when the area to be transplanted is not spacious.
Note: In our clinic, we include one Platelet-Rich Plasma (PRP) session during the hair transplant operation. This will significantly influence the engraftment process ensuring the maximum regrowth result.
During the procedure, up to 4000 grafts are implanted into a particular area on the scalp. The DHI operation lasts longer when compared to the classic FUE technique. As the method requires precision of the procedure, more attention and attentiveness is needed which, as a result will raise the overall cost of the operation. Since the process of opening the microchannels to transplant the extracted hair follicles is different from the classic FUE technique, it is important for operation to be performed by an experienced specialist with in-depth knowledge. As the microchannels are opened one at a time in the DHI method, a low experienced surgical team can cause inaccurate insertion angles.
Direct Hair Implantation, like any other hair transplant technique, seeks to reverse hair loss created by thinning hair, bald spots and receding hairlines. It leaves no linear scars after the operation, is known to heal quicker and is completely painless.
Following a DHI hair transplant surgery, avoid activities that causes excessive sweating such as cardio exercise for at least one month and heavy lifting for at least 60 days. Steam rooms, saunas, and other similar activities should also be avoided. Do not drink any alcohol for at least 1 week after the operation to ensure quick healing. Be cautious, do not touch or comb any areas that received grafts, as they will be sensitive.
