DHI Hair Transplant with Choi Pen
Direct Hair Implantation for maximum density, natural angle control, and faster healing. The Choi pen technique perfected by our expert surgical team.
What is DHI Hair Transplant?
DHI (Direct Hair Implantation) is an advanced hair transplant technique that uses a specialized instrument called the Choi implanter pen. Unlike traditional FUE where channels are opened first and grafts are implanted separately, DHI combines both steps into a single motion.
The Choi pen is a precision medical device that holds a single follicular unit graft. When the surgeon positions the pen on the scalp and activates the mechanism, it simultaneously creates a micro-channel at the exact depth, angle, and direction needed, and deposits the graft in one motion. This eliminates the separate channel-opening phase entirely.
This technique offers several advantages including higher density potential, excellent angle control for natural hair growth patterns, shorter graft out-of-body time, and slightly faster healing due to smaller incisions.
DHI at a Glance
Advantages of DHI Technique
No Channel Opening Required
Unlike traditional FUE where channels are opened first and grafts inserted later, DHI combines both steps. The Choi implanter pen simultaneously creates the channel and places the graft, reducing trauma to the scalp.
Higher Density Packing
The precision of the Choi pen allows grafts to be placed closer together, achieving higher density per square centimeter. This is particularly valuable for patients seeking maximum fullness in specific areas.
Shorter Out-of-Body Time
Because grafts are implanted immediately after extraction, they spend less time outside the body. This can improve graft survival rates as follicles are less exposed to environmental stress.
Faster Healing
The Choi pen creates smaller, more precise incisions compared to traditional channel-opening tools. This results in less tissue trauma, less bleeding, and faster healing with minimal crusting.
Better Angle Control
The Choi implanter pen provides excellent control over the angle and direction of each implanted graft. This is critical for achieving a natural hair growth pattern, especially at the hairline.
Suitable for Unshaved Procedures
DHI is particularly well-suited for unshaved hair transplants as the pen can navigate between existing hairs with precision. This makes it an excellent choice for women and patients who need discretion.
DHI vs. FUE: Side by Side
How DHI Works at Our Clinic
Consultation & Planning
Digital trichoscopy analysis determines your donor density, hair caliber, and graft needs. The DHI plan is designed with precise density mapping for each zone of the recipient area.
Needle-Free Anesthesia
Our proprietary needle-free system delivers anesthesia painlessly using high-pressure air technology. No needles at any point during the procedure.
Graft Extraction
Using MicroFUE 0.6-0.8mm punches, individual follicular units are extracted from the donor area. Each graft is immediately loaded into a Choi implanter pen.
DHI Implantation
The loaded Choi pen simultaneously creates a micro-channel and implants the graft at the precise angle, direction, and depth. Single-hair grafts are placed at the hairline, multiples behind for density.
DHI Hair Transplant Questions
QWhat is DHI hair transplant?
DHI (Direct Hair Implantation) is an advanced hair transplant technique that uses a specialized tool called the Choi implanter pen. This pen simultaneously creates a tiny channel in the scalp and implants the graft in one motion, eliminating the separate channel-opening step used in traditional FUE. The result is faster healing, higher density potential, and excellent angle control.
QHow is DHI different from FUE?
In standard FUE, the surgeon first opens all channels in the recipient area, then implants grafts one by one into these pre-made channels. In DHI, there is no separate channel-opening step. The Choi pen creates the channel and places the graft simultaneously. This reduces the time grafts spend outside the body and allows closer graft placement for higher density.
QIs DHI better than FUE?
Neither technique is universally better. DHI excels at high-density packing and hairline work where angle control is critical. FUE may be preferred for covering very large areas efficiently. At Trabzon Hair Center, we often combine both techniques in a single procedure: DHI for the hairline and front zone, FUE for the crown and larger areas.
QWhat is the Choi implanter pen?
The Choi implanter pen is a specialized medical device that resembles a hollow needle attached to a spring-loaded mechanism. The surgeon loads a single graft into the pen, positions it at the desired angle and depth on the scalp, and presses the mechanism to simultaneously create a micro-channel and deposit the graft. This requires significant skill and experience to use effectively.
QIs DHI suitable for women?
Yes, DHI is an excellent choice for women. Its precision makes it ideal for unshaved procedures, as the Choi pen can navigate between existing hairs. The smaller incisions mean less visible healing signs, and the high-density capability addresses the diffuse thinning pattern common in female hair loss.
QHow many grafts can be placed with DHI?
DHI can achieve 40-60 grafts per square centimeter, compared to 30-40 with standard FUE channel methods. In a single session, we typically place 2,000-5,000 grafts using DHI or a combination of DHI and FUE techniques.
QIs DHI more expensive?
DHI may carry a slight premium due to the specialized Choi pens (which are single-use medical devices) and the additional skill required. However, at Trabzon Hair Center, we recommend techniques based on your clinical needs, not price. Contact us for transparent pricing based on your specific case.
QWhat is the recovery time for DHI?
DHI recovery is slightly faster than standard FUE due to the smaller incisions. Most patients can return to desk work within 3-5 days. Redness and micro-crusting typically resolve within 7-10 days. Full growth timeline remains the same: visible results at month 6, full density at month 12-18.
DHI Hair Transplant in Turkey
DHI hair transplant represents one of the most significant advances in hair restoration technology. The Choi implanter pen, originally developed in South Korea, has been refined and perfected by Turkish surgeons who perform more hair transplant procedures than any other country in the world. At Trabzon Hair Center, we combine DHI with our MicroFUE extraction technique for optimal results in both extraction and implantation.
The Choi pen technique is particularly valuable for certain clinical scenarios: patients requiring maximum density in specific areas, hairline reconstruction where angle control is critical, women's hair transplant cases requiring the unshaved approach, and patients who want the fastest possible healing time. The ability of the Choi pen to place grafts between existing hairs without damaging them makes it the ideal tool for adding density to thinning areas.
At Trabzon Hair Center, we do not believe in a one-technique-fits-all approach. Our surgeons are equally skilled in DHI, MicroFUE, and Sapphire FUE. During your free consultation, we assess your specific case and recommend the technique or combination of techniques that will deliver the best result. Many of our procedures use a hybrid approach: DHI for the hairline and frontal zone where precision is paramount, and MicroFUE for larger coverage areas where efficiency matters. This tailored strategy, combined with our needle-free anesthesia and hospital-grade facilities, ensures every patient receives the highest standard of care at a competitive price.
