DHI (Direct Hair Implantation) is an advanced hair transplant technique that uses a specialised instrument called the Choi implanter pen to create the recipient channel and place the graft in a single motion. This eliminates the separate channel-creation step used in standard FUE, giving the surgeon more precise control over angle, depth, and direction of each individual graft.
DHI is particularly valued for hairline refinement, temple reconstruction, crown densification, and no-shave transplants — situations where precision matters more than raw graft volume. At MedProper Istanbul, DHI is performed by named, board-certified surgeons using single-use Choi pens in a JCI-accredited hospital environment.
The extraction phase is identical in both DHI and FUE — individual follicular units are harvested from the donor area using a micro-punch. The difference lies entirely in how grafts are implanted.
| Feature | DHI (Choi Implanter Pen) | FUE (Pre-Made Channels) |
|---|---|---|
| Channel creation | Choi pen creates channel and places graft simultaneously | Surgeon creates channels first, then grafts are placed with forceps |
| Angle control | Surgeon controls angle at point of implantation | Angle set when channel is created (before graft insertion) |
| No-shave option | Yes — only the donor area needs shaving |
DHI (Implantarea Directă a Părului) este o tehnică de transplant capilar care folosește un implanter Choi pentru a crea canalul receptor și a plasa grefa într-o singură mișcare. Oferă control precis al unghiului și permite proceduri fără ras. Extracția grefelor este identică cu FUE.
La MedProper Istanbul, DHI costă de la 2.200£ / 2.800$ / 2.600€ all-inclusive (până la 4.000 grefe). Prețul include chirurgul, hotelul, transferurile, PRP, medicamentele și îngrijirea post-operatorie pe 12 luni. În Marea Britanie, DHI costă 10.000 până la 14.000£. În SUA, 12.000 până la 17.000$.
Niciunul nu este universal mai bun — excelează în lucruri diferite. DHI oferă precizie superioară pentru linia frontală, permite proceduri fără ras și implantează grefe între firele existente fără deteriorare. FUE gestionează mai eficient un număr mai mare de grefe și costă mai puțin. Ratele de supraviețuire a grefelor sunt echivalente (90-95%). Chirurgul dvs. va recomanda cea mai bună tehnică pentru cazul dvs. specific.

Bottom line: DHI and FUE produce equivalent graft survival rates and long-term results. DHI offers superior precision for targeted work and enables no-shave procedures. FUE handles higher graft counts more efficiently and costs less. Your surgeon will recommend the optimal technique based on your specific hair loss pattern, graft needs, and preferences.
The Choi implanter pen is a hollow, pen-shaped instrument with a fine needle at the tip (0.5-1.0mm diameter). The implantation process works as follows:
This one-step process means the graft spends less time outside a protected environment. In FUE, the channel is created first, and the graft is placed afterwards — introducing a brief but measurable delay between channel creation and graft placement. DHI eliminates this gap.
Multiple Choi pens are used simultaneously (typically 6-8 pens loaded in rotation) to maintain workflow efficiency. While one pen is being used by the surgeon, others are being loaded by the assisting team.
MedProper surgeons sometimes use DHI for the frontal hairline (where precision is critical) and FUE for the mid-scalp and crown (where volume is more important than individual graft placement). This hybrid approach delivers the best of both techniques. Pricing is discussed during the consultation.
One of DHI's most significant advantages is the ability to perform a no-shave (or partial-shave) hair transplant. Here is how it works:
Standard transplant: The entire head is shaved to 1-2mm. This makes extraction and implantation easier and faster, but the patient's hair loss and the procedure itself are visible for 2-3 weeks until hair grows back.
DHI no-shave transplant: Only the donor area is shaved (back and sides). The recipient area retains its existing hair at full length. The surgeon implants grafts between existing hairs using the Choi pen, which can navigate between longer hairs without damaging them.

Limitations:
MedProper DHI no-shave price: from £1,470 / $1,875 / €1,720 all-inclusive (same price as standard DHI).
Step 1 — Consultation and hairline design. Your surgeon assesses your hair loss, discusses your goals, and draws the proposed hairline or densification map while you sit upright. You approve the plan before the procedure begins.
Step 2 — Donor preparation. The donor area (back and sides) is trimmed to 1-2mm. For no-shave DHI, only the donor area is shaved — the rest of the head retains its existing hair.
Step 3 — Local anaesthesia. Needle-free comfort anaesthesia is applied to both donor and recipient areas. The procedure is completely painless once anaesthesia takes effect.
Step 4 — Graft extraction. Individual follicular units are extracted from the donor area using a micro-punch (identical to the FUE extraction method). Grafts are sorted and stored in chilled holding solution.
Step 5 — Choi pen implantation. The surgeon loads each Choi pen with a graft and implants it directly into the recipient area at the precise angle, depth, and direction. Multiple pens rotate in sequence (6-8 at a time) to maintain workflow efficiency. Single-hair grafts are placed at the hairline edge. Multi-hair grafts are placed behind for density.
Step 6 — Post-operative care. Aftercare instructions, medication, and follow-up scheduling. The recipient area requires gentle handling for 10 days. A protective headband is provided.
Total procedure time: 5 to 7 hours for 1,500-2,500 grafts. 7 to 9 hours for 3,000-4,000 grafts.
| Timeline | What to Expect |
|---|---|
| Day 1 | Mild redness in donor and recipient areas. Numbness fades within hours. No significant pain. |
| Days 2-3 | Post-op check at clinic. First gentle wash demonstration. Possible mild forehead swelling (resolves in 2-3 days). |
| Days 4-7 | Tiny crusts around each graft. Donor area healing rapidly. For no-shave patients, existing hair conceals most visible evidence. |
| Days 7-10 | Crusts shed during daily washing. Donor area fully healed. Recipient area slightly pink. Safe to return to work. |
| Weeks 2-4 | Transplanted hairs shed ("shock loss" — completely normal). Follicles remain alive beneath the surface. |
| Month 3 | New hair growth begins. Initially fine and wispy. |
| Months 6-8 | 50-70% of grafts visible. Noticeable density improvement. |
| Month 12 | Full result. Hair can be cut, styled, and treated normally. |

Da. DHI este singura tehnică care permite în mod fiabil transplanturi fără ras. Doar zona donatoare (spatele și lateralele) este tunsă. Zona receptoare își păstrează părul existent la lungime completă, ascunzând procedura. Prețul DHI fără ras la MedProper este același ca DHI standard: de la 2.200£ / 2.800$.
DHI poate transplanta până la 4.000 de grefe într-o singură ședință la MedProper. Pentru pacienții care au nevoie de mai mult de 4.000 de grefe, se recomandă FUE sau o Mega Ședință (până la 6.000 grefe). Alternativ, o abordare hibridă (DHI pentru linia frontală, FUE pentru coroană) poate combina precizia cu volumul.
Nu. Ambele tehnici folosesc același protocol de anestezie locală. Faza de extracție este identică. Faza de implantare cu Choi Pen se simte la fel ca plasarea cu pensete. Disconfortul post-operator este echivalent.
5 până la 7 ore pentru 1.500-2.500 grefe. 7 până la 9 ore pentru 3.000-4.000 grefe. DHI este ușor mai lent per grefă decât FUE din cauza încărcării câte una a Choi Pen, dar acest timp suplimentar aduce o precizie mai mare.
Cronologia este identică cu FUE: pierdere de șoc în săptămânile 2-4, creștere nouă de la luna a 3-a, densitate vizibilă la lunile 6-8, rezultat complet la 12 luni.
