Patient Care Information

Clinical Governance & Trichology Safety Standards

"DHI hair transplantation combines individual donor-graft harvesting through Follicular Unit Excision with implanter-assisted placement in the recipient area. At Meva Clinic, the placement workflow is integrated with donor assessment, individualized hairline design and graft-allocation priorities to support natural-looking coverage, donor-aware planning and long-term visual balance."

Final treatment suitability, operating physician assignment, surgical planning, and medical decisions are confirmed only after medical history review, in-person consultation, diagnostic tests, anesthesia evaluation, and doctor availability.

About This Procedure

Why Choose Meva Clinic?

No-shave option available. High-density implantation using the specialized Choi Pen for faster healing.

A DHI hair transplant in Istanbul differs from other methods at one stage: placement. Grafts are still harvested individually by FUE, but each follicle is then loaded into a Choi implanter pen and placed at a planned angle, direction and depth. This control suits hairline work, targeted thinning areas and, in selected cases, a no-shave approach. Planning weighs your facial proportions, age, existing hair, likely future loss and donor capacity. The procedure is done under local anaesthesia with no hospital stay; allow about three hotel nights, with a first gentle wash within the first one to three days. Temporary shedding between weeks 2 and 8 is expected, early growth appears around months 3–4, and density keeps developing until months 12–18. Unsure which fits? See our DHI vs FUE comparison.

The Clinical Procedure

Direct follicle transfer without separate channel opening.

1

1. Donor Assessment and Individualized Hairline Planning

Assess hair-loss pattern, donor capacity, facial proportions, recipient coverage priorities and long-term appearance. Confirm the planned hairline and graft distribution before treatment.

2

2. Follicular Unit Excision

Harvest follicular units individually from a clinically appropriate donor area using suitable micro-punch instrumentation. Implanter pens are used later for graft placement, not donor harvesting.

3

3. Graft Preparation and Implanter Loading

Inspect and organize extracted follicular units according to the treatment plan. Load grafts carefully into the selected implanter system to maintain follicle viability.

4

4. Recipient-Site and Placement Planning

Confirm the intended angle, direction, spacing and distribution for the hairline and treated areas. The exact site-creation workflow depends on the clinical protocol.

5

5. Implanter-Assisted Graft Placement

Place grafts using implanter pens according to the individualized plan, supporting controlled depth, angle and distribution across the recipient zone.

6

6. Aftercare and Clinical Follow-Up

Provide the first-wash plan, early-care instructions and structured follow-up pathway, connected directly with Meva Clinic clinical care.

Recovery & Transformation Journey

1

Days 1–3: First Wash

The first gentle wash is demonstrated by the clinical team within the first 1–3 days. The implantation points left by the Choi pen are protected from rubbing, scratching and pressure.

2

Days 3–10: Crust Care

Small crusts around the implantation points soften with daily washing and usually clear within about 7–10 days. In no-shave cases, the existing hair helps keep the area discreet.

3

Weeks 2–8: Temporary Shedding

Transplanted hair shafts commonly shed while the follicles rest beneath the skin. Occasionally some nearby native hairs shed too; this is expected and temporary.

4

Months 3–4: Early Regrowth

Fine new hairs begin to appear, following the angle and direction chosen for each graft at placement.

5

Month 6: Visible Change

Coverage in the treated areas becomes noticeably visible, and hairs gradually gain thickness.

6

Months 12–18: Maturation & Assessment

Density and hair calibre continue to mature. The result is generally assessed from around month 12 and reviewed through follow-up up to month 18.

The Meva Advantage

Less trauma to the scalp and higher density.

Medical Guidelines & Safety Protocols

Treatment pathways are coordinated with selected specialist medical partners and accredited provider institutions, depending on the procedure and doctor assessment. Below are the clinical guidelines, safety protocols, and medical reference documentation for this procedure.

Indicated / Suitable For

  • Candidates for DHI hair transplant in Turkey with a stable hair loss pattern and realistic expectations of density.
  • Patients with an adequate donor area (occipital and temporal regions) verified during our detailed donor area assessment.
  • International hair transplant patients comparing DHI hair transplant in Istanbul with other advanced micro-grafting techniques.
  • Adults who require a direct hair implantation approach for natural hairline planning or target area density enhancement.
  • Individuals who are medically suitable for local anesthesia and committed to post-operative care and hair transplant travel planning.

Contraindications / Not Suitable

  • Diffuse Unpatterned Alopecia (DUPA) or unstable donor areas where healthy follicles are insufficient for graft extraction.
  • Active scalp disorders such as untreated psoriasis, severe seborrheic dermatitis, or lichen planopilaris.
  • Severe, uncontrolled metabolic conditions, active coagulation disorders, or medical instability under local anesthesia.
  • Extremely weak donor area where graft extraction would cause donor area thinning or overharvesting.
  • Heavy smoking or history of non-compliance with post-operative hygiene, washing, or clinical guidance.

Pre-Operative Evaluation & Diagnostic Checks

1

Pre-Arrival Photo & Document Review: Remote donor assessment and preliminary hair restoration planning for international patients.

2

Trichoscopic Scalp Evaluation: Microscopic mapping of follicular unit density, caliber, and graft extraction capacity.

3

Hairline Design Istanbul Consultation: Collaborative hairline planning taking into account facial symmetry and age-appropriate design.

4

Standard Laboratory Profile: Coagulation tests (PT/INR), blood counts, and infectious disease screenings.

5

Medical Clearance Check: In-person evaluation of scalp condition, cardiovascular readiness, and anesthesia suitability.

Potential Risks & Complications

In compliance with transparent clinical reporting, Meva Clinic ensures patients are fully informed of the physiological risks associated with surgical procedures through accredited partner-hospital safety protocols where clinically appropriate.

Temporary Shock Loss

Normal shedding of native or transplanted hair shafts post-procedure, resolving within 3-4 months.

Localized Post-Op Swelling

Mild forehead or facial edema, managed with rest, head elevation, and cold compression.

Folliculitis & Inflammation

Minor hair follicle irritation in recipient areas, treated with antiseptic solutions or topical antibiotics.

Donor Thinning

Potential overharvesting of the occipital region, mitigated by strict adherence to donor area limits.

Graft Survival Variability

Variation in graft retention caused by scalp circulation, compliance, or individual tissue response.

Asymmetry or Uneven Density

Minor irregularities requiring a secondary density enhancement session in selected cases.

Realistic Expectations & Outcomes

Published FUE studies report mean graft survival of around 90–93% at 9 months when grafts are handled carefully (for example 93.1% in a 248-patient series, Jin et al., J Cosmet Dermatol 2024). Survival depends mainly on graft handling, time outside the body, hydration and temperature control, and aftercare — which is exactly what our protocol is built around, with photo-documented follow-up to month 12.

Revision & Follow-Up Policy

Meva Graft Growth Assurance: Meva Clinic evaluates graft growth after the full maturation period (12–18 months). If clinically meaningful insufficient growth is confirmed, an eligible patient may receive a complimentary corrective procedure, subject to donor availability, clinical suitability, safety and adherence to the recommended aftercare pathway. Travel, accommodation and personal expenses are not included unless separately confirmed in writing. In the first weeks after a hair transplant, additional checks take place on day 3, day 7, day 10 and day 20. For 12 months after your treatment you can also send photos to the medical team whenever you wish and receive their feedback, and your questions are answered remotely.

Frequently Asked Questions

DHI hair transplantation combines individual donor-graft harvesting through Follicular Unit Excision with implanter-assisted placement in the recipient area. The DHI stage relates primarily to graft placement rather than a separate method of donor harvesting.
No. Donor grafts are harvested individually through Follicular Unit Excision (FUE) using micro-punch instrumentation. DHI refers primarily to the implanter-assisted placement stage in the recipient area.
Follicular units are harvested individually from clinically appropriate donor areas after assessing donor density, hair shaft calibre and long-term capacity. This approach avoids creating a linear FUT strip scar.
The implanter pen holds and places the prepared follicular unit according to the planned angle, direction and distribution. It is a graft-placement tool, not a donor-extraction device.
No. Implanter pens can be used through different recipient-site workflows. In some protocols, site creation and placement occur together; in others, implanters are used with prepared recipient sites. The selected workflow depends on the treatment plan and clinical protocol.
Hairline planning considers facial proportions, age, existing native hair, anticipated hair-loss progression and available donor capacity. Implanter-assisted placement follows natural angles and directions to support long-term visual balance.
DHI is suitable for individuals with localized or progressive hair loss who possess sufficient donor density and are cleared for local anesthesia following medical history review. Technique selection is determined through clinical evaluation.
Yes. DHI is performed under local anesthesia to keep the donor and recipient areas numb during graft harvesting and placement. Brief stinging or pressure can occur during initial administration, while patient comfort is monitored throughout the procedure.
No. Because follicular units are harvested individually through Follicular Unit Excision, DHI does not create the linear strip scar associated with FUT surgery. The small donor extraction sites heal separately, with visibility influenced by donor characteristics, extraction distribution, healing and hair length.
The first gentle wash is typically planned within the first 1 to 3 postoperative days and demonstrated by the clinical team, with clear instructions to avoid rubbing, scratching or pressure.
Yes. Temporary shedding of transplanted hair shafts (and occasionally nearby native hairs) commonly occurs between Weeks 2 and 8. This is a recognized part of the post-treatment hair cycle and is followed by gradual regrowth.
Early new growth typically begins around Months 3 to 4, becomes noticeably visible from around Month 6, and continues to gain calibre, density and coverage through Month 12 to 18.
Published FUE studies report mean graft survival of around 90–93% at 9 months when grafts are handled carefully (for example 93.1% in a 248-patient series, Jin et al., J Cosmet Dermatol 2024). Survival depends mainly on graft handling, time outside the body, hydration and temperature control, and aftercare — which is exactly what our protocol is built around, with photo-documented follow-up to month 12.
Meva Clinic evaluates graft growth after the full maturation period (12–18 months). If clinically meaningful insufficient growth is confirmed, eligible patients may receive a complimentary corrective procedure, subject to donor availability, clinical suitability, safety and adherence to aftercare.
DHI workflows use implanter pens during graft placement. Sapphire FUE commonly uses recipient-site channels created with sapphire blades before placement. The appropriate method depends on the recipient area, graft requirements, existing hair, hair length and donor assessment.
Some women can. Female hair loss is often diffuse, so the first step is finding the cause; thyroid problems, low iron or hormonal changes may need medical treatment rather than surgery. Women with a stable, defined thinning area and a good donor zone may suit DHI, often without shaving the whole head. The cost depends on the graft count, the shaving option and the package, and a written quote follows the free online assessment.
DHI pricing depends on more than the graft number. Implanting with a Choi pen takes longer per graft, and a no-shave plan adds time, so the technique and shaving option matter as much as the count. Whether 3,000 grafts is right for you is decided after the donor assessment. The package includes 3 hotel nights, VIP transfers, the control check and first wash, and you receive a written personalised quote after the free online assessment.
In selected cases, yes. An unshaven or partly shaven DHI plan is usually considered for smaller areas, such as the hairline or a defined thinning zone, where the number of grafts is limited. Large sessions normally need the donor area shaved so that grafts can be harvested evenly and safely. Longer hair hides the work sooner, but it does not make healing faster; the decision is made after the donor assessment.
The implanter pen affects placement, not how long hair survives. Grafts are taken from areas that are usually resistant to pattern hair loss, so they generally keep growing long-term. Native hair around them may keep thinning, which is why a doctor may suggest medical treatment. In a published five-year trial programme that enrolled 1,553 men, those taking finasteride 1 mg kept their improvement, while the placebo group continued to lose hair.
Safety depends on the clinic, not the country. Check that the procedure takes place in a licensed medical setting, that your health and blood tests are reviewed first, that you know who places the grafts and that you receive a written plan with aftercare. In a 2025 review of published studies, 442 of 2,353 patients reported a complication, most often pain or discomfort. With Meva Clinic, patient support is available 24/7 on WhatsApp.
Allow 3 nights at a Bosphorus-view partner hotel, which are included; medically, 2 nights is the minimum. DHI is done under local anaesthesia with no hospital stay. VIP transfers take you from the airport to the clinic and the hotel, and before your flight you have a control check and the first wash at the clinic. Most people return to desk work after 3–5 days.
DHI can give precise results, but the pen is only a tool. Quality depends on the team's experience, how gently grafts are handled, how long they stay outside the body and how realistic the plan is for your donor area. Ask how many grafts are planned, who implants them and what follow-up you receive after flying home. Meva Clinic includes long-term follow-up with your personal patient coordinator.
