Treatment Overview
The Direct Hair Implantation (DHI) Implanter Pen Procedure is Korea’s most advanced form of hair transplantation, using the Choi Implanter Pen — a patented tool that allows surgeons to extract and implant hair follicles directly without creating separate incisions.
This technology provides precise control over the angle, depth, and direction of each implanted follicle, resulting in a completely natural appearance and minimal healing time.
Developed and refined in Korea, DHI is now recognized globally as one of the most sophisticated hair restoration techniques available.
Purpose & Benefits
The main purpose of the DHI Implanter Pen procedure is to increase precision, graft survival, and natural design quality while minimizing trauma to the scalp.
Key benefits include:
- No scalp incisions or stitches required
- Minimal bleeding and faster recovery
- Natural growth direction and dense coverage
- Higher graft survival rate (up to 95%)
- Ideal for hairline design, crown correction, and eyebrow restoration
Ideal Candidates
The DHI Implanter Pen method is ideal for:
- Men and women seeking natural, high-precision results
- Patients wanting minimal downtime or visible signs of surgery
- Individuals needing localized correction (hairline, crown, temples)
- Those with sensitive scalps or limited donor areas
- People seeking a no-shave or partial-shave transplant option
Possible Risks & Complications
The DHI Implanter Pen procedure is extremely safe when performed by experienced Korean surgeons.
Temporary side effects may include:
- Mild redness or swelling in the implanted area
- Slight sensitivity for 1–2 days
- Temporary shedding of transplanted hair during the growth phase
Korean clinics minimize these effects with PRP healing therapy, laser recovery treatments, and gentle scalp care protocols.
Techniques & Technology Used
The Choi Implanter Pen is the core of the DHI technique — a precision instrument consisting of a fine hollow needle (0.6–0.8 mm) attached to a plunger.
Each graft is loaded into the pen and implanted directly into the scalp in one motion, ensuring perfect placement without the need for pre-made channels.
Key technologies used in Korea include:
- Choi Implanter Pens for single-step extraction and implantation
- Micromotor Extraction Devices for gentle donor harvesting
- PRP (Platelet-Rich Plasma) Therapy to enhance graft survival and healing
- 3D Hairline Design Software for accurate facial proportion matching
- Low-Level Laser Therapy (LLLT) to boost blood circulation and recovery
This level of precision guarantees consistent density, uniform direction, and undetectable results.
Treatment Process in Korea
Step 1 – Consultation & Design:
A digital scalp analysis determines the number of grafts and designs a natural hairline or density plan.
Step 2 – Extraction:
Individual follicles are extracted from the donor area using micro punches under local anesthesia.
Step 3 – Implantation with Choi Pen:
Each graft is placed into the Choi Implanter Pen and inserted directly into the recipient area — controlling angle, depth, and direction.
Step 4 – PRP or Laser Healing:
PRP plasma or LED therapy is used immediately after implantation to strengthen grafts and reduce inflammation.
The entire procedure typically takes 5–7 hours, depending on graft quantity and area size.
Recovery & After-Care
Recovery is quick and straightforward due to the non-invasive nature of the DHI Implanter Pen.
Most patients return to normal activity within 2–3 days.
After-care guidelines:
- Avoid washing for 48 hours
- Use mild shampoo after 3 days
- Avoid sunlight, sweating, and tight hats for one week
- Attend PRP or laser follow-ups as advised
- Avoid scratching or massaging the scalp during healing
Results & Longevity
Initial hair growth appears within 3–4 months, with full density achieved by 10–12 months.
Because of precise placement and reduced trauma, DHI grafts have a higher survival rate and faster growth cycle than traditional FUE or FUT.
Results are permanent and natural, blending seamlessly with existing hair.
