DHI hair transplantation is a hair transplant technique in which hair grafts are implanted directly into the recipient area using a Choi implanter pen.
At Vega Hair Center, we do not use the DHI technique as a standard procedure for every patient. The choice of technique is determined according to each patient's individual needs.
The level of hair loss, the density of existing hair, the area to be transplanted, donor capacity, and the number of grafts required are evaluated together to determine whether DHI or Sapphire FUE is more suitable for the patient.
1. For Which Patients Do We Prefer DHI?
We particularly prefer the DHI technique for patients whose hair loss is not extremely advanced and who require additional density between their existing hairs.
In some patients, there is still a significant amount of natural hair in the area to be treated. In these cases, the aim is not to cover a completely bald area, but rather to increase visual density by placing new grafts into the spaces between existing hairs.
DHI provides an important advantage in such cases. In particular:
- In cases where additional density is needed between existing hairs
- For localized or limited hair loss
- In areas where preserving existing hair is particularly important
- In areas requiring precise control of angle and direction
- For unshaven or partially shaven hair transplantation in suitable patients
However, every patient has a different hair structure and pattern of hair loss. Therefore, we do not believe that DHI is better than Sapphire FUE for every patient. The correct technique should be selected according to the patient's individual needs.
2. What Is the Main Difference Between DHI and Sapphire FUE?
In Sapphire FUE, microchannels are first created in the recipient area, and the grafts are then placed into these channels.
In DHI, the grafts are loaded into Choi implanter pens and implanted directly into the recipient area.
Therefore, a separate channel-opening stage is not performed across the entire recipient area beforehand.
The Choi implanter makes it possible to create the entry point and place the graft in a controlled manner. This feature is particularly important in cases where transplantation is performed between existing hairs.
3. Why Do We Use DHI Between Existing Hairs?
When working in an area with a high density of existing hair, it is not enough simply to implant new grafts. At the same time, the patient's existing natural hair and hair follicles should be preserved as much as possible.
Thanks to the use of Choi implanters in the DHI technique, grafts can be implanted precisely and in a controlled manner into suitable spaces between the existing hairs.
Instead of creating channels across a large area in advance, grafts can therefore be implanted directly into the planned locations.
At Vega Hair Center, our aim when working in areas with existing hair is to operate as carefully and precisely as possible, minimize the risk of damage to existing hairs and follicles, and add density where needed.
4. How Is a DHI Procedure Performed?
A DHI procedure involves much more than simply using a Choi pen. Donor analysis, proper graft extraction and preservation, appropriate graft selection, correct loading technique, and controlled implantation must all be managed together.
Donor Analysis and Planning
Before the procedure, the patient's donor area is evaluated. Donor density, hair thickness, graft structure, the safe donor zone, the condition of existing hair, and the needs of the recipient area are analyzed. The number of grafts to be used and their distribution across the recipient areas are then planned.
Graft Extraction
Hair follicles are individually extracted from the safe donor area using the FUE method. During extraction, the goal is not only to obtain the required number of grafts. Preserving the donor area's homogeneous and natural appearance as much as possible is also an important part of the planning process.
Graft Sorting and Preservation
The extracted grafts are evaluated according to their characteristics and prepared for implantation. Using single, double, and multiple-hair grafts in the appropriate areas is important for achieving a natural and dense appearance. Graft selection must be particularly careful in aesthetically sensitive areas such as the hairline.
Loading the Choi Implanter Pens
The prepared grafts are carefully loaded into suitable Choi implanter tips. At this stage, preserving the structure of the graft is important. The graft must be positioned correctly inside the Choi implanter and protected from unnecessary trauma during implantation.
Direct Implantation
Using Choi implanters, the grafts are directly implanted into the planned areas. During implantation, density, angle, direction, depth, and the natural growth pattern of the patient's existing hair are all taken into consideration. The objective is not simply to implant the grafts, but to ensure that the newly transplanted hairs integrate as naturally as possible with the patient's existing hair.
5. Why Are Angle and Direction Control Important?
A natural-looking hair transplant does not depend solely on the number of grafts. The angle and direction in which the hairs grow are critically important for a natural appearance.
During DHI, the use of Choi implanters helps provide controlled planning of graft angle, direction, and placement points in suitable cases.
Especially when adding density between existing hairs, the newly implanted grafts should follow the natural direction of the patient's existing hair.
The goal is for the newly transplanted hair not to appear separate from the existing hair, but instead to look like part of one natural and unified hair structure.
6. Unshaven Hair Transplantation with DHI
One of the important applications of DHI is unshaven or partially shaven hair transplantation in suitable patients.
Particularly in patients who wish to preserve their existing hairstyle and who only need additional density in a limited area, it may be possible to perform the procedure without fully shaving the recipient area.
However, unshaven DHI is not suitable for every patient. The decision should be based on factors such as hair length, the size of the recipient area, the required number of grafts, and the density of existing hair.
An unshaven procedure is not an objective in itself; it is simply an option that may be used when appropriate for the patient.
7. Does DHI Always Mean a Denser Appearance?
No. Using DHI alone does not mean greater density or a different outcome.
The density that can be achieved depends on many factors, including donor capacity, hair thickness, graft quality, existing hair density, the size of the recipient area, tissue characteristics, and proper implantation planning.
For some patients, using DHI to carefully increase density between existing hairs may be appropriate. For another patient with a large bald area and a high graft requirement, Sapphire FUE may be the more appropriate option.
8. Choi Implanter and Our Hygiene Protocol
Patient safety and hygiene are important parts of every DHI procedure.
At Vega Hair Center, the reusable body components of the Choi implanter pens are sterilized according to appropriate sterilization protocols before being reused.
However, the Choi implanter tips used to place the grafts are replaced with new ones for every patient and are patient-specific.
In this way, the reusable parts of the equipment are properly sterilized, while the Choi tips that are directly involved in the procedure are replaced for each new patient.
Vega Hair Center's Approach to DHI
The key components of a DHI procedure for us:
Correct Patient Selection + Strong Donor Analysis + Safe Extraction + Proper Graft Preservation + Precise Choi Loading + Controlled Implantation + Correct Angle and Direction + Preservation of Existing Hair
At Vega Hair Center, DHI is not a marketing choice; it is a technique selected according to the patient's individual needs.
Our aim is not to perform DHI on every patient or to claim that one technique is always superior to another.
Our goal is to use the right technique for the right patient based on the patient's hair loss, existing hair, donor capacity, and desired outcome.
