Imagine: You sit in front of the mirror in the morning and see a dense hairline for the first time in years. No receding hairline, no thin parting — just naturally looking hair. This is exactly what over 80% of our patients experience after a complete DHI process in our clinic in Istanbul.However, the path to this is less mysterious than many think — if you know it.

What is the DHI Hair Transplantation Process exactly?
The DHI method (Direct Hair Implantation) uses the so-called Choi Implant Pen: a precise instrument that extracts hair follicles and immediately implants them into the recipient area — without prior incision of channels. It sounds technical, but it makes a crucial difference: The follicles are exposed to stress for a shorter time, which increases the survival rate to up to 95–97%.
The entire DHI Hair Transplantation process is divided into seven clearly defined phases.

The 7 Phases of the DHI Hair Transplantation Process
1. Initial Consultation and Hair Analysis
Everything begins with a digital hair analysis. Our specialists assess the donor density in the back of the head, the depth of the receding hairline according to the Norwood scale (Stage I–VII), and the desired hairline. This consultation lasts 30–45 minutes and is free for Hair360 patients.
Our Tip: Send three recent photos (top view, side, back of the head) — this way we can already provide a realistic prognosis before the consultation.
2. Surgical Planning and Hairline Design
On the day of the operation, the doctor outlines the new hairline. This takes 20 minutes and is crucial: A natural hairline follows slight irregularities; it never looks perfectly symmetrical. Only agree to the design when you are sure — changes are easily possible before the surgery.
3. Anesthesia of the Donor and Recipient Area
Local anesthesia via injection. The first seconds are uncomfortable, after that you feel nothing. Many patients fall asleep during the surgery. Newer clinics use the “No-Touch” pen, which significantly reduces the pressure of the syringe — Hair360 uses this system as standard.
4. Extraction of Hair Follicles
With the Choi Pen or a micro punch, individual follicular units (1–4 hairs) are extracted from the donor area. In a typical session with 3,000–4,000 grafts, this step takes 2–3 hours. The extraction sites heal invisibly within a few days.
5. Preparation and Quality Control of the Grafts
The extracted grafts are examined under a microscope and stored in a special nutrient solution (Hypothermosol or similar). Damaged follicles are sorted out. This phase is crucial for the later survival rate — a step that cheaper clinics often skip.
6. Implantation with the Choi Pen
Now comes the heart of the DHI Hair Transplantation process: The doctor implants each graft individually, precisely determining the angle (35–45°), depth, and direction. This takes longer with the Choi Pen method than with the classic FUE, but the result is denser and more natural. For comparison DHI vs. FUE find a detailed comparison.
7. Aftercare, healing, and growth phase
- Day 1–3: Scalp reddens slightly, minimal swelling is normal
- Day 10–14: Transplanted hair falls out (Shock Loss) — this is not a mistake, but biology
- Month 3–4: First new hairs grow
- Month 6–8: Visible thickening, about 60% of the final result
- Month 12–18: Complete result, natural texture and density

DHI vs. FUE: Which is better for you?
| Feature | DHI (Choi Pen) | Classic FUE |
|—|—|—|
| Channel cuts needed | No | Yes |
| Growth rate | 95–97% | 90–95% |
| Maximum grafts/session | ~3,500 | ~5,000 |
| Shaving needed | Partial | Complete |
| Healing time | Shorter | Somewhat longer |
| Ideal for | Small to medium gaps | Large areas |
| Cost | Higher | More affordable |
What convinces: DHI is the more precise method — especially for hairline design and for patients who do not want a full shave.

Why Istanbul for the DHI process?
Istanbul is the city with the highest density of certified hair transplant clinics worldwide. The reason: Turkish surgeons perform tens of thousands of procedures annually — this brings a routine that is far from being achieved in German or Austrian clinics. The Hair Clinic Istanbul by Hair360 combines this experience with European hygiene standards and German-speaking patient service.

What our patients say
> “I was afraid of the process — but already in the first conversation, every question was answered concretely. 14 months later, I hardly recognize myself.”
> — *Marcus T., 38, Zurich, 3,200 Grafts DHI*
Over 2,400 patients have already undergone the Hair360 DHI process. The referral rate is 94% (internal survey 2025, n=312).

FAQ — DHI Hair Transplant Process
Further information: Hair Transplantation: the complete guide
How long does the DHI hair transplant process take in total?
The surgical part takes 6–9 hours depending on the number of grafts. The visible final result appears after 12–18 months.
Is the DHI method painful?
During the operation, you feel nothing due to local anesthesia. Mild sensitivity and tension in the first few days afterward is normal.
How many grafts are possible in the DHI process?
Typically 2,500–3,500 grafts per session. For larger areas, we recommend a second session or the FUE method.
Do I need to be completely shaved for the DHI procedure?
No — only a partial shave in the donor area is necessary. The recipient area usually remains unshaved in DHI.
Does the hair fall out again after the DHI process?
Temporary shock loss around day 10–21 is normal. The follicles remain in the scalp and start to grow again after 3–4 months.
