Direct Hair Implantation (DHI) is a modern hair restoration technique that involves transplanting hair follicles from a donor site to a recipient site using a specialized tool called a Choi implanter.
Unlike traditional hair transplant procedures that require the creation of recipient sites before implantation, DHI implants hair follicles directly into the recipient area without the need for incisions or sutures. This method allows for more precise and natural-looking results with minimal scarring.
During the DHI procedure, hair follicles are extracted from a donor site, typically the back or sides of the scalp, using a specialized tool called a micro motor. The follicles are then sorted and prepared for implantation using the Choi implanter, which has a hollow needle that creates a tiny slit in the skin and implants the hair follicle at the same time. This process is repeated until the desired density is achieved.
Steps for Direct Hair Implantation (DHI Hair Transplant)
Hair loss is a common problem that affects millions of people around the world. However, thanks to advancements in medical technology, hair transplant procedures have become more popular and affordable.
One such procedure is Direct Hair Implantation (DHI). This technique is becoming increasingly popular due to its ability to produce natural-looking results with minimal downtime.
In this article, we will discuss the steps involved in DHI hair transplant procedure.
DHI is a minimally invasive hair transplant technique that involves transplanting individual hair follicles directly onto the recipient area without the need for incisions or stitches.
This procedure is performed using a specialized tool called a Choi Implanter Pen, which enables the surgeon to implant the hair follicles at a precise angle and depth.
The first step in the DHI hair transplant process is a consultation with a qualified hair transplant surgeon. During this consultation, the surgeon will evaluate the patient’s hair loss pattern, hair quality, and donor hair availability.
The surgeon will also explain the procedure in detail, including the risks and benefits, and answer any questions the patient may have.
The next step is hairline design, which is a crucial part of the DHI procedure. The surgeon will work with the patient to create a natural-looking hairline that complements their facial features.
The hairline design is drawn on the patient’s scalp using a special pen, and the patient is given an opportunity to review and make any necessary adjustments.
At hair extraction stage of DHI method, first donor area is prepared. Before starting hair extraction, local anaesthesia is applied to both donor and recipient areas. Donor area is the area of the scalp where hair follicles or hair grafts will be collected.
Hair extraction is made with special tools. These tools directly collect hair grafts without harming the roots of the hair. After collecting hair grafts, these grafts are places inside a solution at certain temperature. The purpose of this solution is to achieve stronger placement during hair implanting stage.
Once the hairline design is finalized, the donor hair extraction process can begin. The surgeon will use a micro motorized punch to extract individual hair follicles from the donor area, usually located at the back of the patient’s head. These hair follicles are carefully extracted to minimize damage and ensure the highest possible survival rate.
Hair Follicle Implantation
After the donor hair extraction, the surgeon will use the Choi Implanter Pen to implant the hair follicles directly onto the recipient area. The pen creates tiny holes in the scalp, and the surgeon carefully inserts each hair follicle into a hole. This technique allows for precise control over the depth and angle of each hair follicle, resulting in a natural-looking hairline.
After hair extraction phase, collected hair grafts are implanted with special tools called CHOI pens. This tool is called CHOI pens because the tool looks like a special type of pen. Hair extraction tool has a small tip with approximately 1mm diameter.
Extracted hair grafts are directly implanted from the special solution. The waiting period in between is significantly shorter in this method. During implanting, doctor has the complete control over the depth and direction of how hair grafts are placed. Also, placement angle is considered during implanting stage.
After the DHI procedure, the patient will be given detailed instructions on how to care for their scalp and hair. This will include information on how to wash their hair, how to avoid physical activity, and how to avoid exposing the scalp to direct sunlight. The patient may also be given medication to help reduce any discomfort or swelling.
Post-operation care of direct hair implantation is similar to FUE hair implantation. After the surgery, patients need to follow the instruction of the doctor.
To minimize the pain associated with the operation, patients need to use painkiller medication. Additionally, patients need to use antibiotics and anti-inflammatory medication to minimize the risk of infections.
15 days after the surgery, patients can start to shave their hair. If a patient wants to change hair colour, at least 45 days must pass after the operation. Patients need to stay away from the sea and pool for at least 45 days. After swimming, the head should be rinsed with pure water.
Results and Follow-Up
The final step in the DHI hair transplant process is the post-operative follow-up. The patient will be scheduled for a series of follow-up appointments to monitor their progress and ensure that their hair is growing properly.
The full results of the procedure can take several months to become visible, as the transplanted hair follicles take time to grow and mature.
Direct Hair Implantation (DHI) is a modern hair transplant technique that can produce natural-looking results with minimal downtime. The procedure involves four main steps: pre-procedure consultation, hairline design, donor hair extraction, and hair follicle implantation.
With proper post-operative care and follow-up, patients can expect to see a significant improvement in their hair density and appearance.
When Will My Hair Start to Grow?
Generally, the first significant hair growth is observed 6 months after the surgery. However, complete hair growth is achieved within one year.
In some cases, it may take up to 18 months to have complete hair growth. The speed of hair growth depends on the hair characteristics of the patient as well as daily habits.
For example, smokers may experience late hair growth as smoking hinders the development of new hair. Additionally, eating healthy and adopting a healthy lifestyle may help improve hair growth speed.
When patients follow post-op instructions and take care of their new hair after the surgery, they will regain the hairline they have always been dreaming.
FAQs About DHI Hair Transplant
Is DHI hair transplant safe?
Yes, DHI hair transplant is a safe and minimally invasive procedure when performed by a qualified and experienced surgeon.
Is DHI hair transplant suitable for both men and women?
Yes, DHI hair transplant is suitable for both men and women who are experiencing hair loss or thinning.
Will I need multiple DHI hair transplant sessions?
The number of DHI hair transplant sessions required will depend on the extent of your hair loss and the desired density of your hair. Some patients may only require one session, while others may require multiple sessions to achieve their desired results.
Is there a risk of scarring with DHI hair transplant?
No, there is a very low risk of scarring with DHI hair transplant as there are no incisions or stitches required.
How long does it take for the transplanted hair to start growing?
The transplanted hair may start growing within the first three months after the procedure, but full results may take up to a year to become visible.
Are there any restrictions on physical activity after the DHI procedure?
Yes, it is recommended to avoid strenuous physical activity or heavy lifting for at least two weeks after the procedure to avoid damaging the transplanted hair follicles.
