"The direct hair implantation method is a highly refined tool for natural hairline design and crown density. However, preserving the donor area is paramount. A successful hair transplant recovery is a partnership that requires strict adherence to our aftercare, washing, and lifestyle recommendations."

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.

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. 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.

The Clinical Procedure

Direct follicle transfer without separate channel opening.

Hairline Design & Mapping

demarcation of the hairline design Istanbul and donor extraction boundaries based on natural hairline planning.

Local Anesthesia Infiltration

Local anesthesia is administered using micro-spray pressure devices to minimize discomfort before standard infiltration.

Graft Extraction & Sorting

Individual follicular units are harvested using a motorized micro-punch (0.7-0.9mm). Grafts are sorted and hydrated in a nutrient solution.

Direct Implantation (Choi Pen)

Follicles are loaded into a specialized Choi implanter pen and inserted directly into the scalp, controlling depth, angle, and direction.

PRP & Dressing Application

Platelet-Rich Plasma is applied where appropriate to support healing. The donor zone is dressed, and post-op medication is provided.

Recovery & Transformation Journey

Days 1-2 (First Wash)

Donor bandage is removed. The first washing is performed by our clinical coordinators, and aftercare guidance is reviewed.

Days 3-10 (Crust Shedding)

Redness and swelling resolve. Tiny crusts at graft sites are gently washed away following our structured daily protocols.

Weeks 2-4 (Shock Loss)

Temporary shock loss after hair transplant occurs. Transplanted hair shafts shed while active follicles remain healthy under the skin.

Months 3-12 (Maturation)

Regrowth begins at month 3. Initial outcomes are visible at month 6, with final density and natural hairline maturation at months 12-15.

The Meva Advantage

Less trauma to the scalp and higher density.

Clinical Standards & Safety

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

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

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

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

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

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

DHI technique outcomes vary by patient and depend on donor area capacity, graft survival, and compliance. The Choi pen hair transplant provides precise angle control for a natural look. Visible regrowth begins around months 3-6, with full density achieved between 12 and 15 months. No specific density, graft survival rate, or final result can be guaranteed.

Frequently Asked Questions

Direct Hair Implantation (DHI) is an advanced hair restoration technique where hair follicles are extracted from the donor area and implanted directly into the recipient area using a specialized Choi implanter pen. This Choi-style implantation approach eliminates the need for separate pre-made channel incisions, resulting in less tissue trauma and supporting faster hair transplant recovery.

The Choi implanter pen allows the team to place each graft with precise control over its angle, direction, and depth. This is essential for natural hairline planning and creating a seamless transition that blends with your native hair flow.

Ideal candidates are individuals with a stable hair loss pattern, adequate donor area density, and realistic expectations. During your donor area assessment, we evaluate graft quality to ensure we can achieve your density goals without causing donor area thinning or overharvesting.

Shock loss is a temporary shedding of native or transplanted hair shafts that occurs 2-4 weeks after the procedure due to surgical micro-trauma. This is a normal physiological response; the underlying hair follicles remain healthy and will start sprouting new hair around month 3.

Our Istanbul hair transplant coordination includes pre-arrival photo assessments, travel planning assistance, premium hotel accommodation, local transfers, and in-person donor/design consultations. We also provide multilingual coordinator support, first-wash training, and remote post-op follow-up.

While graft survival rates are high when properly managed by experienced teams, individual results vary due to circulation, skin characteristics, and compliance. No specific density, graft survival rate, or final hair transplant result can be guaranteed.
