The DHI Hair Transplant Technique


Hair loss is a widespread concern that transcends age, gender, and cultural boundaries. As advancements in medical science continue to evolve, so do the techniques for addressing hair loss. One such groundbreaking method that has revolutionised the field of hair transplantation is Direct Hair Implantation (DHI). In this article, we will explore the intricacies of the DHI method, its unique features, and the benefits it brings to individuals seeking effective and natural-looking hair restoration.

Understanding Direct Hair Implantation

Direct Hair Implantation is a state-of-the-art hair transplant technique that has garnered immense popularity due to its precision, efficiency, and aesthetically pleasing results. Unlike traditional methods, such as Follicular Unit Transplantation (FUT) or Follicular Unit Extraction (FUE), DHI offers a direct and controlled approach to implanting hair follicles into the recipient area.

The DHI process involves a meticulous and highly specialised method of harvesting, preparing, and implanting hair follicles. The key differentiator is the use of a Choi Implanter Pen, a sophisticated tool that allows for the direct placement of hair follicles without the need for prior channel creation, as seen in other methods.

Step-by-Step Procedure

  1. Consultation and Assessment: Before the DHI procedure, a thorough consultation is conducted to assess the patient’s individual needs, expectations, and the extent of hair loss. A comprehensive evaluation helps determine the optimal course of action and the number of grafts required for the transplantation.
  2. Hair Follicle Extraction: DHI involves the extraction of hair follicles from the donor area, typically the back or sides of the scalp. Unlike FUT, which requires the removal of a strip of tissue, or FUE, which involves extracting individual follicular units, DHI employs a more controlled and less invasive approach.
  3. Graft Preparation: The extracted follicles are then meticulously examined, sorted, and prepared for implantation. This step ensures that only healthy and viable follicles are selected for transplantation, enhancing the overall success of the procedure.
  4. Choi Implanter Pen: The hallmark of DHI is the utilisation of the Choi Implanter Pen, a specialised tool that streamlines the implantation process. The pen has a hollow needle attached to it, enabling the surgeon to pick up individual grafts and directly implant them into the recipient area.
  5. Direct Implantation: With the Choi Implanter Pen, the surgeon makes precise incisions and implants the hair follicles directly into the scalp without the need for creating recipient channels beforehand. This direct approach allows for greater control over the angle, depth, and density of the implanted grafts, resulting in a more natural and aesthetically pleasing outcome.

Benefits of Direct Hair Implantation

  1. Natural-Looking Results: The direct implantation method ensures a natural distribution and orientation of the transplanted hair follicles. This closely mimics the natural growth pattern, making it challenging for onlookers to distinguish between transplanted and existing hair.
  2. Minimised Trauma to Grafts: The Choi Implanter Pen minimises the time that grafts spend outside the body, reducing the risk of damage and dehydration. This translates to a higher survival rate for transplanted follicles and an increased likelihood of successful hair growth.
  3. Precision and Control: DHI provides unparalleled precision and control over the implantation process. Surgeons can adjust the angle, depth, and direction of each graft with precision, ensuring optimal aesthetic results tailored to the patient’s unique features.
  4. Faster Healing Time: The minimally invasive nature of DHI results in faster healing times compared to traditional methods. Patients typically experience less discomfort, swelling, and scarring, allowing for a quicker recovery and return to normal activities.
  5. No Need for Channel Creation: Unlike other methods that require the creation of recipient channels before implantation, DHI’s direct approach eliminates this step. This not only expedites the procedure but also reduces the risk of trauma to the existing hair in the recipient area.
  6. Versatility in Hair Restoration: DHI is suitable for various hair restoration goals, from filling in receding hairlines to addressing more extensive balding. The method’s adaptability makes it an excellent option for a diverse range of patients.


Direct Hair Implantation stands at the forefront of modern hair transplantation, offering a refined and innovative approach to address the universal concern of hair loss. With its unique use of the Choi Implanter Pen, DHI provides patients with natural-looking results, minimised trauma to grafts, precision in implantation, faster healing times, and versatility in addressing various degrees of hair loss.

Kevin was very helpful and put my mind at ease with all my questions before my surgery. I’ve visited serval hair transplant clinics and what they said to me just did not sound right and the price they were giving where outrageous and at one point I wanted to leave the hair transplant. However after speaking to Kevin and his team they have regain my confidence and courage to get this done. I would fully recommend Harley Street if anyone who is wanting to get a hair transplant.
I would like to give a huge thank you to Kevin and the rest of the team for a wonderful experience. I am over the moon with the results already and the high level of professionalism the team showed throughout the day of my operation. I felt extremely comfortable and well looked after during my operation. The team were also very happy to answer any questions I had throughout the day and they continue to communicate daily with myself post operation which puts your mind at ease during your healing process! I would highly recommend going through hairtransplantliverpool if you are thinking of having a hair transplant, you will not be disappointed. Many thanks Jake

After years of struggling with thinning hair I finally decided a permanent solution was required. Much research found hair transplant Liverpool and I started the consultation process. Kevin was very patient as I explored and questioned options that would fit my situation. We eventually settled on a two stage process with the assurance that they would be able to get a good level of coverage. A short trip to their Bury location and the process began. What an amazing team. Dr Kalra took lots of time designing the hairline and I was fully included in the process as I explained what I wanted and was then guided by his expert knowledge. The first stage was 2000 grafts and that sounded daunting. A bit of prep to prepare the donor area for taking the grafts was done with care as they shaved an area in between the top and bottom of my ponytail so that the graft area would not be seen afterwards as the shaved area grew out. Then the only slight pain as the numbing injections went in. 5 rounds of those but after the 2nd round things were quite numb. Having the grafts taken was not painful but I was aware as each was taken. Then a short break and on to numbing the front area ready for implantation. More injections but soon over and over to Dr Kalra to carefully make the 2000 incisions ready for the grafts to go in to. A short break again for lunch and a drink then on to a 3 hour implant session where the team took great care to place each of the grafts in to their new home. Slight pain towards the end as the numbing wore of on the donor area but a couple of paracetamol later and it was ok. Then before I knew it I was talking to Dr Kalra again about aftercare and receiving my care pack. That evening was a bit sore but easily managed by paracetamol and ibuprofen. I slept propped up in bed with a neck pillow and woke up to tightness in the donor and implant areas but no need for any more pain meds. Ok...it looked red and sore but keeping up with the aftercare helped and at day 5 I washed my hair gently. Now at day 6 and almost all tightness gone. There was a little swelling around my eyes but this passed in two days. A review is planned at 3 months then 2nd session at 6 months. I was extremely well cared for and initial results are looking very good. I will post some pics as everything settles down but I am very pleased so far and so glad I chose and trusted the

Had a brilliant consultation with Kevin who talked through the procedure and calmed my fears and nerves about the treatment. Big thanks to Dr. Nayak and his team for the professionalism and care given to me at the surgery and from then on. It's been 5 months since I had the procedure and I couldn't be any happier with the results.
