About This Procedure

Why Choose Meva Clinic?

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

The hair restoration discipline at Meva Clinic redefines natural hairline aesthetics using premium, low-trauma micro-grafting innovations. Our specialized clinical teams use DHI Choi implanter pens to create the recipient opening and place the graft in one controlled step, rather than relying on separate sapphire blade channel opening as in Sapphire FUE hair transplant planning. This direct hair implantation method allows for precise graft angle, depth, and direction control to support strong graft retention. Patients comparing implanter-assisted placement with sapphire channel creation can review the DHI vs FUE comparison. Direct implantation technology is also utilized for reconstructive procedures like an eyebrow transplant. Designed to address advanced hair loss and thinning after a comprehensive donor area assessment and graft planning, all hair transplant interventions feature a comfort-focused local anesthesia protocol, personalized hairline mapping, a premium medical aftercare kit, and structured follow-up support. Not sure which workflow may fit your case? A preliminary review can consider your hair-loss pattern, donor-area photographs, previous procedures and treatment goals before a personalized recommendation is discussed. Final suitability and graft planning are confirmed after medical assessment. Patients who have not yet selected a technique can review the complete Hair Restoration treatment guide.

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

Initial healing and gentle scalp washing demonstrated at the clinic; donor and recipient areas protected according to aftercare instructions.

2

Superficial crusts over recipient sites gradually soften and shed through gentle daily cleansing without force.

3

Transplanted hair shafts commonly shed as follicles enter a temporary resting phase before new growth begins.

4

Fine new hair shafts begin to emerge from the recipient scalp and progressively gain calibre over time.

5

Noticeable improvement in coverage and hair calibre develops across the treated areas.

6

Overall hair calibre, coverage and visual density are assessed through Meva Clinic's structured clinical follow-up as maturation continues.

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

Based on Meva Clinic's internal clinical follow-up, graft growth has been observed to approach 99% in clinically suitable patients who follow the recommended aftercare pathway. The observation reflects the complete clinical pathway—including donor assessment, graft handling, placement and aftercare—rather than an outcome guaranteed by the implanter technique alone.

Revision & Follow-Up Policy

Meva Clinic Lifetime 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.

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.
Meva Clinic's internal clinical follow-up has observed graft growth approaching 99% in clinically suitable patients who follow the recommended aftercare pathway. This is a clinic-observed growth range, not a guarantee that every patient or every graft will achieve the same result.
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.
