    DHI Channel Technique

    DHI Channel Acquisition Technique is one of the most common hair transplantation methods that is frequently used in our country. It is also known as direct hair transplantation or hair transplantation with a pencil. Hair follicles taken from the relevant donor part are transplanted into the hairless area with the help of a pencil. In this method, hair follicles are collected one by one with a pen. The success of the operation is directly proportional to the skill of the doctor who will perform the application at this stage.

    The surgical pen used in DHI Hair Transplantation is 0.6 mm or 1 mm thin. The grafts taken are separated and cleaned. Then, the hairless part of the scalp is transplanted. With this process, which is done without direct channel opening, the time is short as the hair is added directly. In other hair transplantation methods, the channel opening process is applied first. In the application of DHI Hair Transplantation, which is an experienced surgical method, the doctor’s extreme attention is required.

    DHI Hair Transplant Application Process

    DHI hair transplantation is completed as follows, respectively.

    • The grefts of the hair in the area of healthy hair are loosened and collected one by one with the help of a pen.
    • Since tissue may remain in the removed hair follicles, the cleaning process is performed.
    • Hair directions for application are determined by the specialist doctor.
    • The success of hair transplantation is also related to planting in the right directions according to the head structure.
    • The hair follicles collected in the DHI special pen are placed one by one.
    • Pen tip size is determined by the thickness of the hair follicle of the person. Pen tips varying in thickness from 0.6 mm to 1 mm are used.
    • Pen tips varying in thickness from 0.6 mm to 1 mm are used.
    • The grafts taken are added to the slots created in the skin.
    • There is no incision in this method. Thus, there is no seam.
    • Finally, the application is completed by placing.
    • Generally, the recovery time with this method is very short.

    Differences of DHI Hair Transplantation

    The most important difference of DHI hair transplant application from other methods is that there is no incision. The application is made without shaving the hair. It is longer than other methods. For example, in the FUE technique, the duration is 6 hours for 3 thousand roots, while in the DHI technique, it lasts from 6 hours a day to 2 days. In this method, hair follicles are added as soon as they are taken directly. Since it preserves its properties, the field is a method that gives definite results.


    DHI refers to a different implantation technique during FUE transplantation.

    Grafts are first extracted using micromotor assisted staples, as during FUE transplantation. With this technique, there is no need to make incisions in the recipient site.

    Grafts are first inserted into specific implant pens with a hollow needle connected to a tube and plunger device. These implant pens are also known as Choi implants..

    The grafts are gently inserted into the hollow needle placed at the tip of the implanter pen.

    Next, the needle is inserted into the scalp at a right angle of 40-45 degrees so that the incision site is made, then the graft is implanted by pressing the plunger.

    During a DHI procedure, a normal amount ranging from 2 to 6 ChoI implanters and about 15-16 needles are used simultaneously, the device comes in a variety of needle sizes to fit follicular unit grafts.

    The main advantage of the implanter is that more grafts can be placed per cm2 of the recipient area, thus providing a more intensive FUs transplantation. This feature is especially advantageous for the front hairline.

    The biggest disadvantage of the DHI technique is that it is usually a much more expensive procedure compared to other hair transplant methods. In addition, improper graft placement in implant pens and improper bending of grafts during implantation can cause excessive trauma to sensitive hair follicles, which can lead to follicle death.

    Sapphire FUE or DHI-FUE ?

    Both Sapphire FUE and DHI-FUE have almost the same advantages because; opening more channels and placing more grafts at a given cm2 in the recipient area, a dense transplant for both mild forms of hair loss, Class 3 and Class 1, plus a denser and softer front hairline.

    Sapphire FUE also provides another advantage over DHI. Contrary to DHI implants, which have this risk, there is no risk of damaging sensitive hair follicles both during the placement of the graft into the implanter and during the placement of the graft from the implanter to the recipient area.

    Sapphire tip FUE provides the same dense implantation as DHI.

    The sapphire tip has proven its effectiveness to provide a maximum dense transplant on the front hairline and even to create a dense corner fold, and its results are very comparable to DHI implants. Considering that there is no extra cost for Sapphire FUE, there is a lot of extra cost for the DHI procedure to achieve the same result; we don’t see much of a reason to get a DHI procedure. Anyway, we provide DHI-FUE for patients who choose it.
