To obtain a characteristic looking result and to protect the benefactor are from injury, it is so important to settle on the right choice on your hair transplant supplier from the beginning.
By age 50, more than 85 percent of men start to suffer from hair loss. In their lifetime, more than 50 percent of women also experience a noticeable amount of hair loss. As we can see, it is more common in men; yet, it does not mean hair loss is just a men problem. There are several reasons behind this.
What Is DHI Hair Transplant?
DHI hair is one of the most advanced and recent achievements. This groundbreaking Direct Hair Implantation method, which is also referred to as the Choi method, enables hair to be embedded with special care. After extracting and sorting appropriate grafts from recipient areas and embedding them in the needed receptor area, the implantation is completed. In medical terminology, a graft is a healthy tissue that is extracted from a suitable area of the patient’s body for implantation to the needed area. The entire healthy hair follicle or multiple follicles that are implanted directly into the related receptor area are contained in hair transplantation grafts.
Hair follicles from the donor area are extracted by a micro motor and are transplanted into the receipt area with a device, which resembles a pen containing a hollow needle. This device is called ‘the Choi pen’. The Choi pen has a sharp tip. Its hollow needle makes it possible to insert the grafts with the needle. This is why the DHI method is also known as ‘the Choi method’. To fit each patient’s grafts, the Choi pen comes in a wide variety of needle sizes.
This method is one of the most researched methods of transplantation by people who want to have the procedure done nowadays. When we say DHI, the first thing that comes to our mind is mostly the FUE method as DHI is a modification of FUE. During FUE, before implanting hair follicles, a surgeon manually cuts channels, which is in your scalp. In DHI, specialists use the Choi pen, which enables them to do both at the same time. This is the most significant point which differentiates this method from other methods. It enables the hair transplant to be performed without shaving the patient’s head. After the extraction of hair follicles, they are embedded in 1-2 minutes, which means that they remain outside the body for only a short time of period.
It is possible to expect natural and healthy results with DHI. Thanks to the DHI method, people can regain their hair.
Development Of Direct Hair Implantation
For almost all people who look for treatments for hair loss, the DHI method is convenient. However, this was not always like that. Just a certain type of hair was available in the early stages of the Choi pen technique: thick, straight hair. Fortunately, this is no longer an issue and individuals with all types of hair can experience natural-looking outcomes. A specialist at Kyungpook National University in Korea developed the DHI method. Their device is generally called the ‘original’ implanter pen device which is the Choi implanter pen. Experts working in this sector began to examine after its development to better understand this new method and to see whether it helps all patients equally and universally. However, according to the results of their research, they noticed that not all people were suitable for the Choi implanter pen during hair transplant surgery. In the initial transplantation with Choi pens, better results were observed for Asian patients with hair loss compared to other ethnic groups, primarily due to their hair’s thickness and texture. The experts came to the final results: in general, Asian people’s hair is thick and straight. However, other races’ curly characteristics and thinner diameter, make it hard to load their hair into the implanter correctly and to be planted concurrently in the scalp. The needle sizes used in those studies ranged between 0.8-0.9 mm. Follicles may experience a bending effect without the appropriate diameter and straightness or may result in an improper graft placement and severe trauma for the follicles.
For that reason, it was confirmed that not all patients are suitable candidates for the use of the Choi implanter pen during the hair transplant procedure. However, some physicians opposed to this argument, stating that with improved knowledge and expertise with the Choi implant pen, successful graft placement with any type of hair may be possible. With scientific and technological advancements, the hair restoration techniques have progressed over the last decade and reached a point where it is possible to perform hair transplantation using the Choi implanter pen with any type of hair and a fair number of grafts. So, almost all patients choose the DHI implant method if they prefer, and can experience the same reliable, efficient, consistent, safe, and natural-looking outcomes as those first Asian patients. For all patients, hair growth timelines are similar as well.
The Direct Hair Implantation Method
Steps which are used to perform a successful DHI hair transplant are as follows;
- Extracted grafts and donor’s hair are transmitted into the implanter Choi pen by a specialized surgeon.
- To be given back to the expert physician, the graft is carefully placed into the hollow needle which is located at the end of the implanter pen.
- The surgeon inserts the needle at an accurate 40-45 degree angle into the scalp.
- Generally, a number of 2-6 Choi implanters and roughly 15-16 needles are used simultaneously during a procedure.
Before Direct Hair Implantation
If the individual has an ongoing scalp condition, he/she must be treated before the operation. Antibiotics must be taken if there are any active acne. Excess dandruff must be dealt with. In a potential precancerous active lesion, specimens should be collected for biopsy and sent to the pathology laboratory in order to be examined. Patients should stop using a wig or prosthetic hair two weeks before hair transplant and should be rinsed off if it is fixed on the scalp with glue or an adhesive. The use of cosmetics such as hair gel should be stopped. Using solutions to avoid hair loss, such as minoxidil, must be discontinued one week before the operation.
After Direct Hair Implantation
The amount of time needed for recovery, healing, and growth of the hair is up to 12 months after hair transplantation About two to three weeks after hair transplantation, most patients undergo a condition referred to as ‘shock hair loss’ where new hair grafts enter a resting period and therefore the hairs are shed. This period is completely normal and natural. Therefore, you do not need to be scared if you experience this period after your hair transplant procedure. Your new and natural hair will soon start to grow in its place after the shedding of transplanted graft. Your newly transplanted hair will start its natural growth cycle in about 2 to 2.5 months and will grow nearly 1,5 cm per month. After the 9th month, the hair that is transplanted will become stronger and will improve in texture. At about 12th month, it will blend with your own natural hair structure.
Is Direct Hair Implantation Operation Painful?
Local anesthesia is usually used for the DHI technique, which means that you will not feel any kind of pain. Clinics carry out hair transplantation with sedation to improve the comfort of their patients during surgery. Without any discomfort or suffering, the patient undergoes the procedure. You can use a painkiller that was prescribed by your doctor if you feel any pain.
Advantages Of The DHI Technique
As hair transplantation can be performed directly in the required areas, DHI may be helpful for those who have ongoing hair loss. With all of this, hair transplantation with the DHI procedure requires skill and care. As a result, it may be somewhat more expensive than other types of hair plantation. However, naturalness to be achieved will be worth the price.
Thanks to the Direct Hair Implantation procedure, patients who suffer from hair loss DHI and FUE follow a similar procedure and leaves no visible scars after transplantation. Another important thing is that, unlike other hair transplants, DHI requires no major surgery. Furthermore, with this procedure, the risk of infection can be greatly minimized.
No scarring: Incisions generally remind us of scarring. However, thanks to the Choi pen technique, which is used in DHI hair transplant, there is no need for any incisions and therefore no scars. Additionally, the healing process is much quicker because there is no need to sew the source region where the hair follicles are embedded. To mitigate the chance of scarring as much as possible, thanks to the Choi pen, extractions are more well-distributed.
Consistent results: The Choi pen helps to control the depth, angle, and trend of the planted hair follicles as an advanced technique. It makes your new hair grow just like your original hair and the result will be natural.
The growth angle, colors, and the natural path of the hair are taken into consideration when the hair tissues and roots are relocated to the operation area. Therefore, in all sensitive areas including temporal sides and hairline, you get natural results. That means, with the DHI transplant, you will easily recover with no scars or stitches.
Unlike typical sowing techniques, the DHI method promotes multiple root transplants for fast results and more hair growth. For instance, in the FUE technique, patients have to wait at least 3 days to wash their hairs. However, in the DHI technique, you can wash your hair the same day after sowing.
Though it depends upon your choices, sowing can be operated without shaving. If you select the DHI method, you will quickly return to your normal life without feeling any differences thanks to the unshaved hair implantation.
Disadvantages Of The DHI technique
While it cannot be considered as a disadvantage, the DHI technique must be carried out by highly qualified doctors with great care. As the density level is very important in the application process, for the aim of achieving the best results, operations should be performed by qualified doctors. Furthermore, hair transplantation with the DHI technique is more expensive than the other hair transplant techniques.
Compared with the Follicular Unit Transplantation and Follicular Unit Extraction, the cost of the DHI can also be higher. The cost of DHI hair transplantation is between 2.000 and 3,500 euros. The reason behind this, it may be hard to find a hair clinic that performs this operation, or which has the experience. As the DHI is a new procedure, there are likely to be fewer surgeons who are trained and certified in the DHI Hair Transplant method.
In general, the DHI Hair Transplant procedure is more difficult and hair follicles may be damaged more easily if the procedure is not done with great care. This draws attention to the importance of having an experienced and certified DHI professional.
