Hair transplant also known as hair restoration or hair transplantation is a surgical technique in which new hair follicles are transplanted from a hair-loss resistant area to a balding or hair thinning area. In fact, Hair Transplant is a permanent replacement treatment to restore the hair in the balding area.

What is Direct Hair Implant (DHI)?
Direct Hair Implant is a hair transplantation technique performed by using special DHI Pen, also called DHI Implanter, or CHOI Pen. In the DHI technique, the extracted grafts are directly implanted into the recipient area.
The innovation lies in the use of the Choi Implanter Pen, the tool that allows for direct transplantation of the grafts without having to create channel incisions in the donor area first. The site creation and the graft insertion are carried out simultaneously in DHI.
After the hair is put inside these pens, they are implanted directly in the area. By this, because the canals are opened exactly the size of the graft, there are less transplantation marks and bleeding.

When to consider DHI Hair Transplant
. If you have thinning hair
. If you have bald spots
. If you have a receding hairline
How do I prepare for a DHI procedure?
Your surgeon will provide thorough preoperative instructions, answer any questions you may have, take a detailed medical history, and perform a physical exam to determine your fitness for surgery.
In advance of your procedure, your surgeon will ask you to:
. Stop smoking at least six weeks before undergoing surgery to promote better healing.
. Avoid taking aspirin, certain anti-inflammatory drugs and some herbal medications that can cause increased bleeding.
. You may be asked to take a shower and wash your hair with regular or antibacterial soap.
. Regardless of the type of surgery to be performed, hydration is very important before and after surgery for safe recovery.
DHI procedure is usually performed on an outpatient basis. Be sure to arrange for someone to drive you home after surgery and to stay with you at least the first night following surgery.

Who are the Ideal Candidates for a DHI Procedure?
. Men who have been losing their hair due to male pattern baldness for more than five years or who have progressed to a Norwood class 3, which is the earliest stage of male hair loss, or above.
. Men who have realistic expectations and who understand that their hair loss might continue to progress even if they are taking prescription medication to stop the progression.
. Men who have been balding for many years and whose pattern has stabilized and are interested in growing hair to provide a more youthful appearance.
. Men and women who have lost hair due to trauma or burns.
. Patients who need front Eye-brow, Beard and mustache transplantation.
. And someone who has adequate hair growth or follicles that can be used for transplant.

. This procedure is done under the effect of local anesthesia, so it does not directly interfere with the functioning of the heart, etc. But, there are always risks to the patients having serious heart diseases and they should consult with the surgeons before taking the treatment.
. Heavy drinkers and smokers are also not allowed to undergo the treatment because of the risk of internal and external bleeding. If they have to take the treatment, they have to abstain from their drinking and smoking habits at least a few weeks before the time of the procedure.
. People with diffuse hair loss have inadequate donor supply hence they are advised against undergoing a hair transplant. They have a higher risk that the grafts are too weak and will not take at the recipient area.
. Those who suffer from thinning hair may also not be suitable for DHI surgery since there are no distinct bald patches and not enough space to implant the new hair. There is a risk that the new grafts will be rejected or that they will dislodge the neighbouring hair.
. Also, the risks of a DHI procedure can be minimised if your scalp is normal or loose. People with a tight scalp are not the best candidates for the procedure, as it would be difficult for the surgeon to insert the grafts.

What are the Advantages and Disadvantages of DHI technique?
. Reduced time of grafts remaining outside the body, thus ensuring strong and healthy placement of the grafts.
. The direction of hair growth with the hair sowing pen can be determined as desired. And it is much more possible to give the hair a more natural look.
. Not being necessary to open channels in the area where the hair will be planted, so, the existing hair follicles are not damaged during transport.
. Adequate hair follicles survival rates, the success rate is around 90%.
. Reduced bleeding during the creation of the recipient area. Reduced trauma during graft handling, thus leading to less damage in the blood supply to the implanted area.
. Fast recovery during the postoperative phase, the patient can return back to his/her normal routine quicker.
. The recipient site does not have to be shaved, as it is a more suitable procedure that enables this condition.
. The pen nibs who are specific to the patient and only have one use are utilized.
. The operation is realized with much less pain and bleeding.
. The operations are only performed by the specialized hair surgeons.
. Thanks to suitable genetics and insensitivity of DHI, transplanted roots stay forever.
. The physician and staff members are exposed to long-term training period so as to specialize in utilizing this technique.
. It is generally a more costly procedure when compared to other hair transplantation methods.
. This method requires more attention as well as accuracy during the procedure.
. In some instances there is a chance of losing transplanted hair, and this is referred to as “shock loss.”
. It might take months for hair to grow into the area
Risks and Side effects
What are the risks and Side effects of DHI procedure?
Like any surgery, a DHI procedure involves certain risks. But with the right specialist by your side, they can be kept at the lowest level possible. In addition, the occurrence of adverse events after a DHI procedure is considered to be relatively low compared to other surgical procedures. Here is an overview of the possible risks associated with a DHI procedure.
. Poor results
It may happen that the result does not meet your expectations. Either the hair density is too low or the hair grows in an unnatural direction and creates a non-aesthetic image. Failure to match the natural hair growth direction may also result in an unsatisfactory appearance. However, with a trained specialist who has been performing hair transplants for years, you need not be afraid of this risk.
. Pain during or after a DHI procedure
The modern DHI method, is minimally invasive and done under local anaesthesia. Therefore, the patient will not feel any pain during the procedure.
. Inflammation and swelling
Of course, wounds may swell and redden after surgery. These risks of a DHI procedure are bound to occur at least for a short time after the surgery has been performed. If the patient applies some antiseptic and soothing cream, inflammation and swelling will be relieved in 1-2 days. You can also reduce swelling by sleeping on a high pillow with your head elevated.
Itching is quite common after surgery, it means that the wounds are in the process of healing. However, you must desist from scratching the itchy areas, since it can displace the newly implanted grafts.
Bleeding may occasionally occur within 2 weeks after the operation. To avoid or minimise it, the patient should never scratch the scalp or pick the scabs. Avoid strenuous physical activities, drinking alcohol, smoking, and taking aspirin within at least 7-10 days as well. If bleeding takes place, put a clean gauze cloth on the bleeding areas and gently apply pressure with your fingers.
In the DHI method, Due to the fact that the extraction and implantation methods used in DHI involve moving single follicles at a time, the risk of infection is very small.
With the DHI method, you do not have to expect any apparent scars.
. The grafts fall out
Some patients experience what's known as "shock loss," which causes all of the transplanted hair to fall out at once. However, it's very unlikely that this hair loss is permanent and typically new hair will grow in its place. This risk can be diminished by a comprehensive preoperative examination of the patient. It is possible to predict how good the grafts will take by assessing the quality of the scalp and hair.
What is the difference between DHI and FUE?
The main difference between FUE and DHI is in the way grafts are implanted into the recipient area.
While during FUE the surgeon manually implants the extracted grafts, with DHI a specific implanter tool (also known as Choi Implanter Pen) is used. Moreover, FUE requires canal opening prior to implantation. DHI allows the implantation to happen right after extraction, without the need to create holes or slits for the grafts to be implanted.

During DHI Procedure
Before the anaesthesia and implantation, your surgeon will draw your new hairline on your scalp based on your goals and the quality and amount of hair available in your donor area. You will receive local anaesthesia on your donor area. After the anaesthesia has taken effect, the surgeon will start extracting the hair manually, one-by-one, using punches with diameter <=1 mm from the donor area.
In the DHI technique, the hair is then immediately implanted into the recipient area using a special implanter tool known as a Choi Implanter Pen. With this method, there is no need for canal opening prior to implantation and the hair does not remain outside the body for very long. The Choi Implanter allows the surgeon more control over the angle, direction and depth of the hair transplantation and hence results in a more natural look.
DHI hair transplant Stages
The Stages of DHI procedure are as follows:
. Collection: In this stage, with a specific tool called “micro motor”, the hairs who are smaller than 1 diameter are removed from the scalp and collected. There will not be any scars or cuts and the collected hairs are immediately suitable for transplantation.
. Arrangement: The hairs are carefully put in the pens which contain suitable canals for the height of the hair strand.
. Plantation: The hairs inside the pens are stuck in directly in the hairless area, thus the canals are opened and the hairs are planted at the same time. The hair is transferred easily, suitably for the angle and the depth in the area. They will stay forever and never be lost post transplantation.

The Healing process after DHI Hair Transplantation
Hair transplantation using the DHI technique requires only the infliction of minuscule wholes. Because no incisions are inflicted and no channels are opened, scar tissue and complications are much less observed than the other techniques.
Following your surgery, you will have a post-op consultation where your surgeon will discuss the aftercare with you, clear any doubts and answer any of your question. You will often receive a post-op package containing all the necessary shampoos or medication that will be needed following the surgery.
It is safe to say that the healing process after the DHI technique is generally very speedy. Little scabs disappear after 5 – 6 days.
Bear in mind that anywhere between weeks 2-8 you will undergo ‘shock loss’ where most of your transplanted hair will fall out. This is a normal part of the process. The hair will grow back gradually, both in the recipient as well as the donor areas.
Here are some aftercare tips for DHI surgery:
. Wait a few days after the surgery to wash your hair. Only use mild shampoos for the first few weeks.
. You should be able to return to work or normal activities in about 3-5 days.
. Don’t press a brush or comb down over the new grafts for about 3 weeks.
. Don’t wear any pullover shirts and jackets until your doctor say it’s OK.
. After surgery go home and rest. Keep your head up about 45 degrees. A recliner will be helpful.
. You can work out again after 1 month
. You can swim and do steam baths after 1 month
. You can wear hats after 10 days, and hard hats after 4 weeks
. A headwrap will be placed around your head for the first night. The next morning, take scissors and just cut the headwrap and remove it. Don’t pull it off, or you might pull out some grafts. Don’t leave it on more than the first night either, your head will swell more later on if you do so.
Don’t worry if some hairs fall out. This is part of the process. Transplanted hair may not grow much or seamlessly match the hair around it for a few months.

. Day 0: the day of the surgery is counted as day 0.
. Day 1-5: The first 2 weeks after a DHI procedure are the most critical ones. During the first 5 days, patients may experience swelling of the forehead and at the back of the head, which is the donor area. The skin may also look red at the areas where all the tiny incisions were made for the newly transplanted hairs. This redness usually resolves after the first week or 2. After only a few days, the donor area is no longer tender.
. Days 6 – 10: At this point, patients no longer experience any swelling and the redness should only be faint or completely gone. For each follicular unit transplanted, a “crust” will form which is the attached skin layer drying out. This scab can be gently removed by soaking and gentle rubbing with fingers. By day 10, all the crusting should be gone and the transplanted hairs will appear like a “crew-cut” haircut.
. Week 2- 3: The transplanted hairs will start to shed at this point, and by the end of the 3rd/4th week, most will be gone. This is a normal part of the healing process and is totally expected. The newly transplanted hairs go through a shedding process as the actual hair shaft is released, but the actual follicular unit and bulb are totally intact starting to grow a new hair shaft. Patients may feel like the operation was a failure but this is part of the normal hair cycle.
. End of Month 1 – Month 2: The hair follicles have entered into the resting phase of their cycle. The length of the resting phase can vary before they start to grow again. At this stage, patients will appear exactly as they did prior to surgery with regards to the amount of hair present.
. Months 2 – 4: The new hairs should start coming out. For some patients, their transplanted hairs start growing early in the timeline; for others, they start growing later. Patients will see the new transplants, but they will be thin at this stage as they begin to emerge from the scalp. Most of the native hair will be growing back at this time. The donor area is healing and any redness at the donor site will resolve.
. Month 6: Transplanted hair has entered the anagen phase and begins to grow (finally…progress!). At this point usually, the doctor used to see you in follow up.
. Months 6 – 9: Patients will start to see a considerable amount of hair emerging from the scalp. The hairs are thinner; many of the transplanted hairs will be over 3 inches or longer and is able to be groomed. Toward the end of this period, the hair will show textural changes and start to thicken up. The donor area will be completely healed at this point. The original donor laxity is restored by month 9.
. 1 Year: Patients have achieved about 80% of the hair growth of the transplanted hairs. Most of the hairs will have emerged from the scalp. At this point, further density is unlikely to noticeably improve without further surgical and/or nonsurgical intervention (PRP). It’s time to focus on outcome maintenance!
. After 1 year: For some patients, they achieve the full appearance by 1 year; others will take longer for the hairs to emerge and increase their density and thickness.
Additionally, as the hair grows longer, that provides a fuller appearance since the volume of hair is increased at the transplanted area.
