What Is DHI Hair Transplant?
DHI (Direct Hair Implantation) is a hair transplant method in which follicular units are harvested from the donor area and placed directly into the recipient area using a specialised device called a Choi implanter pen. The Choi pen is an applicator fitted with a hollow, fine, angled needle. Each graft is loaded into this needle; when the pen is pressed against the recipient skin, the incision and implantation occur simultaneously. There is no separate channel-opening stage.
The technique became widespread in South Korean-origin clinics during the latter half of the 2000s. Today it is one of the two most commonly performed modern hair transplant techniques worldwide, alongside FUE.
How Does the Choi Pen Work?
The Choi pen operates on a principle similar to a syringe, but its needle tip is angled and sharp, designed to carry a hair follicle without causing damage. The procedural flow is as follows:
- Immediately after each graft is extracted from the donor area with the micro-motor, a technician loads it into the needle of the pen.
- The surgeon presses the tip of the pen into the recipient area at the desired angle and direction — this movement creates a micro-incision in the skin.
- When the spring-loaded mechanism is triggered, the graft is pushed into the opening and the follicle is immediately positioned.
- The pen is withdrawn; the process is repeated for the next graft.
In a typical DHI procedure, three to six pens are kept in rotation simultaneously — one group loading, another monitoring implantation angles. Team coordination and pace directly influence the outcome.
The Key Difference Between DHI and FUE
FUE and DHI use the same principle at the graft extraction stage: individual follicle harvesting with a micro-motor. The difference lies in the implantation stage:
| Stage | FUE | DHI |
|---|---|---|
| 1. Graft extraction | Micro-motor, one by one | Micro-motor, one by one |
| 2. Channel opening | Separate stage (sapphire or steel tip) | None — Choi pen combines incision and placement |
| 3. Graft placement | Into pre-opened channels, separate stage | Immediately as the pen is triggered |
| Total stages | 3 | 2 |
| Time graft spends outside body | Moderate (includes channel stage) | Short (placed as soon as extracted) |
| Hourly graft rate | High | Low–moderate |
| High-density zones | Limited | Advantageous |
In concrete terms: in FUE, all channels are opened first, then the grafts are placed separately. In DHI, each graft is placed the moment it is extracted. The practical consequence of this difference is that the ischaemia time of each graft (the period it spends outside the body) is shorter with DHI. Some studies identify this as a small advantage for graft survival; however, survival depends primarily on storage conditions and team discipline, not technique alone.
The second difference lies in directional and angular control. Because the Choi pen is inserted directly into the skin at 30–45 degree angles, the direction of hair emergence can be adjusted precisely. This control can be valuable in areas such as the frontal hairline, where single-row placement and high density are required.
For a more detailed comparison, we recommend reading this page alongside the FUE hair transplant in Northern Cyprus page.
Advantages and Limitations
Advantages of DHI:
- Short ischaemia time: Grafts spend less time outside the body — a small but measurable benefit for survival.
- High density: In the frontal hairline and crown areas, 60–80 grafts/cm² can be achieved, and in some cases higher.
- Shave-free option: In limited areas — particularly the frontal line and small touch-up zones — it is possible to perform DHI without fully shaving the donor or recipient area. A significant advantage for female patients.
- Precise directional control: The angle of the pen directly determines the hair emergence angle, making natural-looking hairline planning more straightforward.
- Reduced perceived trauma: Because no separate channel is opened, the sensation of trauma to the recipient area may feel milder; medically, however, recovery time is comparable to FUE.
Limitations (and why we make a point of explaining them):
- Fewer grafts per hour: For the same graft count, a DHI procedure takes longer than FUE. A 3,000-graft case that takes six to seven hours with FUE may take eight to ten hours with DHI. For very large cases (more than 3,500 grafts), the extended operating time can be a limiting factor for patient comfort.
- Surgeon and team experience is critical: The Choi pen has a steep learning curve. The likelihood of angular errors, graft damage or superficial placement increases in inexperienced hands. The team must maintain the same precision over many hours.
- Higher cost per graft: Consumables (multiple Choi pen tips) and team-hour requirements make DHI typically 10–25% more expensive than FUE.
- Not practical for very large areas: For cases at Norwood Stage 6–7 requiring 4,500 or more grafts, the process becomes very lengthy; FUE or a two-session plan is generally more practical.
At Nis Clinic, we do not offer DHI as something we recommend to every patient. Your hair structure, loss pattern and target density — these three parameters determine whether DHI is the right choice for you.
The DHI Hair Transplant Process at Nis Clinic
A hair transplant is not a single-day procedure. For DHI, the journey begins with a consultation and extends to a 12-month review. It runs across four stages.
Consultation — Medical Assessment of DHI Candidacy
Consultations take place online (Zoom or WhatsApp video) or in person at our clinic. The topics we cover specifically for DHI include:
- The type of hair loss (androgenetic alopecia, diffuse loss, remission following alopecia areata) and its stage (Norwood/Ludwig scale).
- Target area: hairline, frontal crown, temporal peaks, full coverage — DHI is most beneficial in the hairline and small-to-moderate density goals.
- Planned graft count: the comfortable range for DHI is 2,500–3,500 grafts.
- Shave preference: for female patients, whether shave-free DHI is feasible is assessed. For male patients, partial shaving is generally recommended.
- Previous transplant procedures, current medications (finasteride, minoxidil, anticoagulants) and chronic health conditions.
The consultation concludes with a clear picture: is DHI appropriate, or is FUE or Sapphire FUE a better fit, approximately how many grafts are needed, and which area is being targeted. The price range is shared at this stage.
Planning — Donor Analysis, Density Map and Hairline Design
DHI planning involves three layers of assessment:
- Donor analysis: Follicle density per cm² in the nape region is measured under microscopy. Because DHI requires more time per graft, economical planning of donor use is important — the decision on how many grafts can be allocated to the target area is settled here.
- Density map: The recipient area is divided into three zones: frontal hairline, frontal crown and temporal peaks. Target density is determined separately for each zone. In DHI, 60–80 grafts/cm² in the frontal line and 40–55 grafts/cm² in the crown zone are typical targets — higher figures are technically possible but reduce long-term donor sustainability.
- Hairline design: Drawing on his plastic surgery background, Dr. Meyzin designs a hairline that suits your facial proportions and accounts for your future loss potential. For female patients, the priority is densifying the existing hairline and creating a soft transition towards the forehead. For male patients, a mature hairline appropriate to age and forehead width is adopted — a plan that cannot be defended at 35 with the aggressive line of a 22-year-old is a plan that leads to regret.
Procedure Day — 6–9 Hours Under Local Anaesthesia
A DHI procedure is typically somewhat longer than FUE. Average duration is six to nine hours; planning of 3,500 or more grafts can reach ten hours. The procedure is completed within the same day.
Typical schedule:
- 08:30 — Arrival at clinic, blood pressure and glucose check, blood test review
- 09:00 — Donor area shaving (full or partial — according to plan), disinfection, final hairline confirmation
- 09:30 — Local anaesthesia
- 10:00 — Graft extraction begins
- 13:00 — Lunch break, light meal
- 13:30 — Choi pens begin loading and implantation
- 17:30–18:30 — Procedure complete, dressing applied, first-wash and aftercare instructions given
Throughout the DHI procedure, multiple technicians load the pens while the surgeon oversees implantation angles and density. At Nis Clinic, Dr. Meyzin personally places grafts in the critical zones — particularly the frontal hairline. The extraction stage is more collaborative. General anaesthesia is not used; DHI is safely performed under local anaesthesia.
Recovery — 24 Hours, 7 Days, 30 Days, 6 Months, 12 Months
The DHI recovery timeline closely follows that of FUE; the technical difference between the two methods has no critical impact on healing time.
- First 24 hours: Minor oozing is normal. Keep your head elevated on the pillow. Analgesics are prescribed.
- Days 2–3: The first wash is performed at the clinic under nurse supervision. Forehead swelling may occur; it typically subsides by day three.
- Day 7: Crusting begins to shed; most has cleared by around day ten. A check-up appointment takes place.
- Weeks 3–6: Shock loss — the majority of transplanted hairs shed. The follicles remain alive and will regrow.
- Months 3–4: New growth begins. Fine, soft hairs emerge.
- Month 6: Approximately 60–70% of the final result is visible.
- Month 12: The final outcome. Hair thickness, texture and density are fully established.
We remain in contact via WhatsApp throughout follow-up and respond to photographic queries within 24 hours. Where needed, hair PRP treatment can be recommended as an adjuvant from month three onwards — it supports regrowth after shock loss.
Who Is DHI Suitable For?
DHI is not the answer to every case of hair loss; when applied to the right candidate, it is a powerful technique. We share the decision framework we use in candidacy assessment.
Ideal Cases for DHI
- Female patient who does not wish to shave: Androgenetic alopecia in women (Ludwig Stage 1–2) or frontal-line densification cases are DHI's strongest indication. A shave-free approach speeds up return to normal social life.
- Frontal hairline design is the primary goal: Single-row precision and a high-density target are the area in which DHI truly shines.
- Male patient, Norwood Stage 3–4: With planning in the 2,500–3,500 graft range focused on the frontal line and midline, DHI is a comfortable choice.
- Beard and eyebrow transplant: Narrow area, precise angle requirements, low-to-moderate graft count — these align well with DHI's parameters. (See the beard and moustache transplant in Northern Cyprus page for details.)
- Previous FUE patient seeking frontal-line densification: New grafts are placed while preserving existing hair; DHI's partial shave advantage comes to the fore here.
Situations Where We Consider FUE Instead of DHI
- Very large case (more than 3,500–4,000 grafts): An extended operating time undermines patient comfort; FUE or a two-session plan is generally more practical.
- Norwood Stage 5–6, widespread loss: Where full coverage is the target, FUE's higher hourly graft rate is advantageous.
- High demand for grafts-per-hour: For patients who want a maximum-graft procedure in a single day, FUE is more appropriate.
- Budget is the deciding factor: DHI carries higher consumable costs; where budget is the determining variable, FUE simplifies the equation.
- Very fine, fragile follicle structure: The likelihood of damage during loading into the Choi pen increases; in these cases, an FUE-plus-implanter-forceps combination may be preferred.
Shared contraindications (applicable to both techniques):
- Not performed in patients under 18. In patients under 25, loss patterns may not yet be stable — careful assessment is required.
- Active, rapidly progressing loss → loss should be stabilised with medical treatment first.
- Scarring alopecia, active phase of lichen planopilaris → specialist assessment required; may not be suitable for every patient.
- Uncontrolled diabetes, thyroid disease, autoimmune condition → internal medicine review required first.
- Anticoagulant use → internal medicine or cardiology consultation arranged prior to surgery.
- Insufficient donor area → expectation management is critical; a more modest target is set.
At Nis Clinic, we do not say "DHI for every patient" or "FUE for every patient." Competence in both techniques means freedom of choice for us — and the right decision made together with you, not for you.
Why Northern Cyprus? Why Nis Clinic?
For hair transplantation, there are hundreds of clinics worldwide offering DHI. Here are three concrete reasons to consider Northern Cyprus — and us.
1) Dual Competence in FUE and DHI, with Surgical Oversight
Op. Dr. İbrahim Meyzin is a Specialist in Plastic, Reconstructive and Aesthetic Surgery, Cyprus Turkish Medical Association (CTMA) Registry No: 969. In his clinical practice he performs both FUE and DHI. This is an important distinction: a centre limited to a single technique cannot offer genuine flexibility in candidacy assessment. At Nis Clinic, the question "which of these suits your case?" is answered with clinical freedom, not a pre-packaged offer.
He is personally present throughout every procedure and places grafts in critical zones such as the frontal hairline himself. The model of "technicians operate, doctor oversees" is not practised at Nis Clinic.

2) Northern Cyprus Location — Privacy, Climate, Recovery
Northern Cyprus is, in practice, a sanctuary: one hour and fifteen minutes from Istanbul, four to four and a half hours from London. Treatment without a Schengen entry in your passport; the likelihood of running into someone you know is virtually zero. DHI in particular suits professionals who want to recover before returning to work, and patients who prefer not to share a visible change beyond their immediate circle. After your procedure, you can spend five to seven days on the coast in Kyrenia in mild weather — stress levels during healing genuinely matter to follicle survival.
We have three clinic locations: Nicosia (main clinic and all procedures), Kyrenia (on the coastline, positioned for medical tourism patients), and Famagusta (serving patients on the eastern side of the island).
3) Transparent Pricing
DHI hair transplant costs in international comparison:
- United Kingdom: €7,000–€12,000+
- Türkiye: €2,000–€4,500 (the lower end carries risk; the upper end reflects quality clinics)
- Nis Clinic (Northern Cyprus DHI package): €2,500–€5,000
DHI is typically 10–25% more expensive than FUE for the same graft count — due to Choi pen consumable costs and the longer operating time. The exact figure is confirmed after consultation; graft count, number of target zones, shave preference and supplementary procedures (mesotherapy, PRP) determine the range.
Package includes: airport transfers, 1–2 nights' accommodation, the procedure, medications, first wash, WhatsApp support and 12-month follow-up. There are no hidden charges.
If you are not looking for the cheapest option and if your surgeon's qualifications and whether they personally perform the procedure matter to you, you are in the right place.
