What is DHI Hair Transplant?

DHI — Direct Hair Implantation — is a refinement of the FUE extraction method that changes how grafts are implanted. Rather than creating all recipient channels first and then placing grafts, DHI loads each follicular unit directly into a Choi implanter pen and implants it in a single motion.

The Choi pen is a hollow-tipped instrument that allows the surgeon to control the depth, angle and direction of each graft at the moment of implantation — simultaneously creating the channel and placing the follicle in one precise movement. This eliminates the waiting phase between channel creation and graft placement that occurs in standard FUE.

At Hairmedico, Dr. Arslan Musbeh performs every stage of DHI personally — including loading each graft into the Choi pen and executing each implantation. This level of control is what distinguishes our results from technician-led procedures.

Key DHI advantage: No pre-made channels means the recipient area does not need to be fully incised before implantation begins. This reduces overall trauma, shortens the time grafts spend outside the body, and allows for denser packing — particularly in the hairline and crown.

DHI vs FUE — The Core Difference

Both DHI and standard FUE extract follicular units from the donor zone using the same punch technique. The extraction phase is identical. The difference is entirely in the implantation step:

  • FUE (with Sapphire or steel blades): Surgeon creates all recipient channels first, then places grafts. Two separate phases — channel creation, then implantation.
  • DHI (Choi pen): Grafts are implanted directly, without pre-made channels. Channel creation and implantation happen simultaneously in a single motion.

The practical consequence: DHI allows the surgeon to achieve higher density, more precise angle control, and shorter graft-out-of-body time. It is the preferred technique for hairline restoration, crown density work, and patients with existing hair in the recipient area who want to avoid shaving. See our full FUE vs DHI comparison guide for a complete breakdown.

The DHI Procedure at Hairmedico

A DHI session at Hairmedico follows the same overall structure as an FUE session, with the implantation phase handled differently.

Extraction Phase

Dr. Arslan extracts individual follicular units from the donor zone using a 0.7–0.9mm punch, following the Algorithmic FUE™ sequencing protocol. Grafts are immediately transferred to preservation solution.

Loading Phase

Each graft is carefully loaded into a Choi implanter pen by Dr. Arslan. Multiple pens are prepared in rotation to minimise the time any graft remains outside the body. This loading phase requires precise handling — a damaged follicle at this stage cannot be recovered.

Implantation Phase

Dr. Arslan implants each graft using the Choi pen, controlling the angle (0–90°), direction and depth of every unit individually. This is the most technically demanding phase of DHI and the primary reason why surgeon involvement is non-negotiable for a natural result.

Why DHI Produces Superior Hairline Results

DHI is not universally superior to FUE — the right technique depends on the patient's anatomy, area of restoration and graft count required. However, for specific goals, DHI consistently outperforms standard FUE:

  • Hairline definition: The single-motion implantation of each graft at an individually selected angle allows for a hairline that mimics natural growth patterns with exceptional precision.
  • Dense packing: DHI allows grafts to be placed more densely without pre-made channels crowding each other. Critical for restoring the appearance of full density in thinned areas.
  • No-shave DHI: DHI can be performed without shaving the recipient area — the Choi pen implants between existing hairs. Suitable for patients with partial thinning who cannot undergo a visible shave period.
  • Reduced trauma: No pre-made channels means fewer open incisions in the recipient zone at any one time, reducing bleeding and accelerating healing.

Who is DHI Best Suited For?

Dr. Arslan recommends DHI for the following patient profiles:

  • Patients requiring hairline restoration (Norwood II–IIIa) where angle precision is paramount
  • Crown restoration requiring dense, natural-looking coverage
  • Patients with existing hair in the recipient area who want minimal shaving
  • Cases requiring 2,000–4,500 grafts where maximum density is the primary goal
  • Beard transplants and eyebrow restoration, where precise direction control is essential

For sessions requiring more than 4,500 grafts, Dr. Arslan may recommend Algorithmic FUE™ or a combined approach — determined after reviewing your photographs.

DHI — Frequently Asked Questions

Is DHI more expensive than FUE?
At Hairmedico, DHI is included in the VIP — FUE–DHI package — our most chosen all-inclusive offering. Pricing is provided on request after photograph assessment, as the number of grafts and session requirements vary by case. The package includes surgery, 5-star hotel (2 nights), VIP transfers, PRP, LOREW kit and 12-month follow-up. See full package details →
Can DHI be done without shaving?
Yes. DHI allows for unshaved (no-shave) procedures in the recipient area, as the Choi pen implants between existing hairs without pre-made channels. The donor zone still requires a light shave. This option is suitable for patients with diffuse thinning who cannot accommodate a visible post-operative scalp period. Dr. Arslan will confirm suitability during assessment.
How many grafts can be implanted with DHI?
A single DHI session at Hairmedico can accommodate up to 4,500 grafts within a 6–8 hour operating window. The one-patient-per-day policy ensures the full session time is devoted to your procedure. For cases requiring more than 4,500 grafts, Dr. Arslan may recommend a combined or staged approach.
What is the DHI recovery period?
DHI recovery is comparable to standard FUE. The donor zone heals within 7–10 days. Scabbing in the recipient area resolves at 10–14 days. Because DHI creates less trauma to the recipient zone (no pre-made channels), many patients report marginally faster healing and less initial redness. Return to office work is typically possible within 5 days.
Is DHI suitable for beard and eyebrow transplants?
Yes. DHI's single-unit angle control makes it the preferred technique for beard, eyebrow and temporal peak restoration, where the direction and angle of each hair is critical to a natural result. Dr. Arslan performs beard and eyebrow transplants using DHI. Submit photographs for a personal assessment.
