As technology continues to advance, medical engineers are developing sophisicated techniques, tools and devices in the hair transplant industry to improve the old existing hair transplant techniques and tools and adopt new scientific approach to make hair transplant easier and time saving for the medical team, comfortable for the patient during and after the surgery and also more safer.
FUT (follicular hair transplant)
In the past 30 years before the emergence of FUE (Follicular Unit Extraction), hair transplant surgeons were using an old painful technique which is called FUT (follicular hair transplant). In the FUT technique, a strip of tissue with hair follicles is excised from the back of the scalp and the incision is then sutured. Hair follicles are extracted from the strip of skin and implanted into the recipient areas by a skilled clinical team.
There are numerous disadvantages in the FUT technique compared to the other techniques like the FUE. Some of the disadvantages include; the risk of scarring and a longer recovery period per treatment session. The FUT technique often leaves a linear scar at the site where the donor strip is excised. Furthermore, FUT treatments can result in stretching of the scalp which can exacerbate the appearance of the linear scar. The stitches used to close the excision will need to be in place for one to two weeks, and it is advisable patients avoid strenuous activity for a few days before the removal of the sutures. Also, the surgeons can extract only up to 2500 hair grafts at most in one session. In addition, while sorting hair grafts from the strip, many roots can be damaged and lose its effectiveness during this process.
FUE (Follicular Unit Extraction),
In FUE, there is no excision but instead, a punch is used to extract follicular units (each with 2-5 hair follicles) from the scalp and these extracted hairs are then implanted into the recipient areas. Hair follicles are removed in a random fashion and is not even noticeable after the donor area recovers. This is the main difference between FUE & FUT.
Some advantages of FUE are, no scars can be found after two weeks of the procedure, and no unusual pains for patients who undergo this hair transplant surgery. FUE hair transplant is considered the suitable method to treat the cases of advanced hair loss, because this technique allows surgeons to extract between 3500-4500 hair grafts during one session of surgery. This technique is one of the best techniques for hair transplantation because the doctor opens the hair channels in the receiving area which allow him to determine the angle of natural hair tendency.
DHI (Direct Hair Implantation)
When did DHI (Direct Hair Implantation) hair transplant begin?
A Greek physician, Konstantinos Giutis began this technique. He founded DHI Medical Group in 1970, and moved to Palo Alto, California, USA. His medical group then spread to San Francisco and Beverly Hills, where it was known as Golden Creek.
The group’s common goal was to solve hair loss problems in 1985, Gautis and his team were able to introduce one of the most revolutionary techniques of hair transplantation: the method of smelting the epidermis, from which time the group became known and took its place.
In 2001, the first conference of the International Society of Plastic Surgeons was held, during that conference doctor Gautis introduced his technique which hold the name of his medical group “DHI’ which is characterized by careful handling with the scalp. And the capacity to implant the maximum number of follicles without leaving visible scars into the skin layer. Since then, this technique has been considered the newest and most famous method, taught at the international medical schools.
In the same year 2001, Giutis presented at the International Conference of the International Society of Plastic Surgeons for the first time the technique of direct hair transplantation “DHI”.
What is “DHI”?
DHI (Direct Hair Implantation) is a type of FUE hair transplant technique and the main difference is how the hair is implanted at the recipient site. In an FUE hair transplant, the hair transplant surgeon makes incisions over the entire scalp and places the follicular units into these incisions. However, the DHI hair transplant technique requires the use of a patented tool to implant each hair, one at a time into the scalp without the need for any incisions. It is performrd by using a special tool called “Choi implanter” it looks like a pen so it is called “Choi pen”. The grafts which extract through DHI are directly implanted to the recipient area. This new technology assurance you the natural hair line from the front side of your head. Also it can give you a good density hair apparence.
Advantages of DHI Technique
Getting a high rate of viable healthy follicles.
Reducing time of procedure (with a medical team experienced in Choi implanter pens technique) as creating the incisions and implanting the follicles are combined in one step. It also reduce trauma during follicles transfer, and causing less damage in the blood supply to the implanted area.
No Scarring, the DHI tool ensures that hair extractions are well-distributed and so there is no scaring. This helps in faster recovery.
A DHI Direct Hair Implantation is a very safe procedure with low risk of infection and complications, and a very has a high rate (over 90%) of hair survival. DHI technique is one of the latest hair transplant methods currently available and it helps in your hair restoration and your confidence, permanently.
DHI is one of the best technique for your hair transplant because ensures strong and healthy placement of the grafts and there is adequate survival rate of hair follicles. It also reduce bleeding drastically during the creation of the recipient area. DHI gives good density of hair and natural looking results. The tool controls the depth, angle and the direction of the implanted hair follicles so your new hairs grow as your natural hairs.
