There is a lot of confusion regarding what is DHI,

So to answer your query lets start by understanding what exactly DHI is ?

What is DHI Hair Transplant?

DHI method/ technique is an advancement of FUE method where the hair follicles are extracted from the donor area via utilizing a micro surgical tool and then transplanting them into the recipient site using DHI Implanter , a pen-like device that contains a hollow needle.

The tools used in DHI treatment/ technique are US patented and single-use. They provide angle, depth, and direction to a surgeon thereby ensuring the natural-looking hairline. DHI technique is performed by MD surgeons only who are certified by London Hair Restoration Academy.


DHI Procedure

Now, lets get acquainted with the DHI tool which makes all the difference.



The Choi Implanter is a pen-like device featuring a hollow needle attached to a tube and plunger apparatus.

During the procedure with the Choi Implanter, the physician/technician loads harvested follicular units into the implanter pen.

Then using the forceps, the graft is placed gently into the hollow needle (at the end of the implanter) and handed back to the physician.

The surgeon then inserts the needle at an appropriate angle in the scalp (making the incision site) and implants the graft by pressing down on the plunger.

Normally, anywhere from 2-6 Choi implanters are used concurrently during a procedure, and the device comes in a variety of needle sizes to fit single, double, and triple follicular unit grafts which are US patented and are used only once.

How is the DHI Implanter used?

1. Hair follicles are placed one by one into Choi’s implanter. However, care should be taken while handling the grafts as they are very delicate.

2. The most suitable angle for inserting the grafts in the tool is 45° to 50°.

3. During the operation around 2-6 choi pen and 14-16 choi needles are used.

4. According to the thickness of hair and root appropriate pencil is used during the procedure.

What are the 3 steps in DHI hair transplant procedure?

It is a 3 step procedure starting with extraction phase followed by placement phase simultaneously hence giving you natural results.


Lets dive deep into each phase to gain an insight


Hair follicles are extracted one by one from the donor area using a specifically designed disposable tool with the diameter of 1 mm or less.

Then the follicles are kept at a specific temperature in a solution that enhances their development after placement, without separating, cutting or generally handling the grafts.

Right after the extraction process, the hair follicles are implanted directly into the region suffering from hair loss using a patented tool, the DHI Implanter, with a diameter of 1 mm or less.

And you know what’s the best part is ? The doctor does not need to create prior holes or slits before implantation.

Since, there is full control of the depth, direction and angle of the placement of each graft, it will ensure 100% natural results giving maximum visibility.

This assures that the implanted hair will never fall out and will grow for a lifetime.

DHI provides a guarantee on graft survival ratio of 90% implanted hairs.

It is a form of natural hair transplant.

How long will the Surgery last?

The duration of Direct Hair Implantation procedure depends on the extent of the patient’s hair loss.

A patient with a small amount of hair loss may only require a small session lasting around 3-4 hours, whereas an individual with extensive hair loss may require a 2-day procedure, each day lasting around 6 hours.

Generally, the actual procedure can take you up to 6-7 hours in one sitting.

Doctors and their team work efficiently, and don’t rush it to ensure the precise implantation of every hair, guaranteeing natural hair transplant results.

Recovery Process after DHI Hair Transplantation

After the DHI Hair Restoration is completed, crusting will be seen in the transplanting area within 5-6 days.

It takes about twenty days for these crusts to heal and fall off.

Within three months you can see your fresh, bushy and new hair.

However, it will take a year for you to see all your transplanted hair.

Cost is the most important & crucial factor!

So let’s dive deep into it...

What is the cost of Direct Hair Implantation?

Hair transplant is an innovative medical procedure which, when performed by certified physicians in the field, gives a permanent solution to hair loss.

It improves not only the patient’s appearance, but their self-confidence as well. By contrast, a failed hair transplant exaggerates the problem by only providing a temporary solution, at best.Hence a finest and optimum choice has to be taken.

The cost of hair transplant is the main query that needs to be addressed before choosing the method of transplantation. DHI hair transplant cost is principally determined by the number of follicles required to ensure best results to a patient. Generally it is Rs.100 per follicle and the whole DHI procedure ranges from Rs.1.5 lakh to Rs.4 lakh. However, it is not possible to give an accurate estimate over the phone or online.

You will have to meet the experts at clinics near you for a comprehensive hair and scalp consultation. Post consultation the doctor will be in a better position to tell you the exact cost of the treatment.

Your DHI hair transplant Cost Will Be Based on the Following:

Usually, all the countries do not have a uniform price for DHI.There might be a vast difference between the cost in the developed countries and developing countries. While making the decision it is better to compare the prices between the countries. Further, it is not uncommon to see people travelling to different countries for hair transplantation.

Breaking the Myth of DHI:

A lot of people think that DHI hair transplant is too expensive to even consider or it is usually done by the rich and the famous. In this misconception, they lend their trust to uncertified clinics. Before deciding to do anything like this, you must evaluate long-term effects of cheap hair transplant option. These cheap procedures can give unnatural results and leave scars for a lifetime.

A lot of people are now considering DHI for its high success rates and natural results. Additionally, the survival rate of follicles is less than 50% as compared to more than 90% offered by DHI technique. DHI Hair restoration treatments have become even more convenient and affordable with the availability of a variety of financing options.

What are the advantages of DHI Technique?

Among its advantages indicated by some hair restoration experts are as follows:

Reduced time of grafts remaining outside the body enhances the survival rates.

Reduced bleeding during the creation of the recipient area.

Reduced trauma during follicle handling, thus leading to less damage in the blood supply to the implanted area.

Fast recovery during the post-operative 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.

It is also ideal for women since hair shaving is not necessary in the area to be transplanted.

The operation does not include any incision or sewing processes

As the extraction and placement can be carried out simultaneously, the plantation phase is shorter

The operation does not cause any scars or traces of implantation Provides magnificent symmetry on the front hairline.

The angle and direction of each hair follicle can be accurately determined.

Benefits of Direct Hair Implantation:


What are the disadvantages of DHI Technique?

• Generally, it is a more costly procedure when compared to other hair transplantation methods.

• This method requires more attention as well as accuracy during the procedure which can cause the operator stress. Due to this it could likely affect both the extraction as well as the implantation process, causing possible damage while handling the grafts.

What are the risks associated with DHI Technique?

• If you are at risk of responding badly to local anesthesia then there could be a potential danger of undergoing DHI.

• If you have concerns about this due to any past or current medical conditions then you should discuss this with your general physician in the first instance and make sure that you also discuss it in detail with your doctor

• There is a risk of infection. But since, DHI involves moving single follicles at a time, the risk of infection is very minimum.

• The immediate result of your DHI procedure could result in your friends and family noticing that you have had a hair replacement treatment, so if you are worried about this then you may want to consider this as a potential risk of DHI.

• However, the immediate effect of the DHI procedure is probably more of an advantage than a risk if you wish to improve the hair coverage of your head as soon as possible.

The DHI Procedure: What To Expect?

Highest Graft Quality and Natural Results

Direct Hair Implantation is a very safe procedure with low risk of complications, and a very high rate (over 90%) of hair survival. DHI method is superior to other hair transplant methods currently available. Not only will DHI help in restoring your hair but also your confidence, permanently by giving it a natural look

A Complete Pain Relief Method in Hair Transplantation

Thanks to the use of sedation given under the direct supervision of the Anesthesiologist (An anesthesiologist is a doctor (MD or DO) who practices anesthesia) , you will no longer feel any pain during the administration of local anesthesia prior to the hair transplant procedure.


Yes, a small number of patients may not qualify for either medical reasons or higher than normal expectations. To address these issues, various sophisticated diagnostic systems have been found, including:

-Alopecia Tests: These are a series of coordinated tests that examine the scalp and skin very closely, followed by accurate measurements of the available number of hair for transplant. Cutting edge mathematical modeling is used to ensure a homogenous and natural result.

-DNA Analysis: A one of a kind test, each patient’s DNA can be tested to understand the cause of the hair loss at the smallest, molecular level.

-Stress Tests: These are a series of trademarked biological tests that measure the level of oxidative stress impacting each patient’s hair. An effective and unique treatment plan, including nutrition and lifestyle advice, can then be developed for each patient to ensure that their hair has the best potential to grow and flourish.

No specific precautions should be taken before the DHI hair transplant procedure. However, it is advised that patients should not take blood thinners at least 7 days prior to the procedure, in order to avoid prolonged bleeding during implantation. Also the patient should avoid vitamins, aspirin, alcohol and smoking as per the direction of the doctor.

Each patient is unique, with individual requirements, so it is generally not preferred to provide a quote or an estimate without consultation and an accurate diagnosis. Moreover, DHI can be 20% more expensive than FUE, but has a consistent hair survival rate of 90%.

The main difference between Direct Hair Implantation (DHI) and other methods of hair transplant is that this technique offers quality results as compared to traditional FUE along with several other advantages. By definition, FUE means Follicular Unit Extraction and hence, placement of the hair follicle is not given as much importance as the extraction process. Most often, forceps are used for placement after many slits/cuts are made in the recipient area. This can lead to uneven healing, scars, and an unnatural result.

In contrast, under DHI technique, the patented DHI Implanter tool is used to precisely control the angle, depth and direction of the implanted follicle without making any cuts which creates a totally natural hairline.

The procedure causes minimum pain and causes less irritation than say getting a tattoo. Further, the procedure is done under local anesthesia so you can relax, listen to music, watch TV, enjoy a light lunch and even nap during the procedure.

DHI uses single-use disposable punches and needles for every session. These instruments are destroyed after every procedure in front of the patient according to the DHI protocols. Hair follicles are extracted one by one from the donor area using a specifically designed disposable tool with the diameter of 1mm or less.

In DHI, there is very minimal bleeding as compared to “FUT” or “Strip” surgery.

Heavy exercise, weight lifting, swimming and scalp exposure to direct sunlight has to be avoided for 15 days after the procedure. The patient can resume light exercise and brisk walks 7 days after the procedure.

The client is prescribed antibiotics and anti-inflammatory course which needs to be followed for 3 days post procedure.

There’s no requirement of any long term medication, as the implanted hair will not fall.However, Minoxidil applications are required to prevent thinning and falling of the existing hair.

Proper care must be taken of the implanted and donor area after the procedure. If not, there could be complications such as folliculitis infection, bacterial infection etc. in such an unforeseen situation, proper and immediate medical attention should be availed.

You will start noticing improvement within 3-4 months, but the complete results take up to a year.

Yes, this is one of the best procedures as it does not require shaving your head.

If there is not enough hair for donor extraction, then sometimes doctors use facial and body hair.

You can return to cardio and swimming 2 weeks after your procedure, but wait a month before resuming intense exercise.

In many cases, you will be able to return to work even the following day, provided you are able to maintain your post-operative routine. Many prefer to take a week off.
