DHI Hair Transplant

DHI, or direct hair implantation, is a variation of FUE that changes how grafts are placed. Grafts are extracted one by one from the donor area exactly as in classic FUE, but instead of opening all the channels first, the team uses pen-shaped implanters that create the opening and place each graft in a single movement.

With a DHI hair transplant in Turkey, Plastic Surgery Turkey Group (PSTG) plans your treatment and coordinates your trip, and the procedure is carried out at a contracted healthcare institution authorised for international health tourism in Istanbul or Antalya. The responsible physician decides whether DHI, classic FUE or a combination suits your hair. Our hair transplant guide gives the wider overview.

Who is a good candidate#

DHI is often considered for:

• designing or refining a hairline, where the angle of every hair is visible;
• adding density to a defined, smaller area;
• working between existing hairs, where the team wants to limit shaving of the recipient area;
• some women with localised thinning, where preserving existing hair matters.

As with all FUE-based methods, you need a stable enough pattern of loss and a donor area that can supply the grafts. DHI is less practical, or may be combined with other placement methods, when:

• a very large area needs covering in one session;
• the donor area is sparse;
• thinning is diffuse or caused by an active scalp condition;
• hair loss is still progressing quickly and has not been assessed medically.

Techniques and options#

How implanter pens work#

Each implanter has a fine hollow needle, and needles of different diameters are chosen to match the size of the grafts, from single-hair grafts at the front of the hairline to larger grafts behind it. A team member loads a graft into the needle; the implanting clinician inserts it into the scalp at the planned angle, direction and depth and presses a plunger to release the graft as the needle is withdrawn. Several pens are usually used in rotation so loading and implanting can continue in parallel.

What DHI offers#

• Close control, graft by graft. Angle, direction and depth are set for each hair as it is placed, which is why DHI is often chosen for hairlines.
• No separate channel stage. Opening and placement happen together.
• Working between existing hairs. Because grafts are placed one at a time, the recipient area can sometimes be left longer.

The trade-offs#

DHI is meticulous, so it can be slower per graft than classic FUE, and very large sessions are sometimes planned differently. Grafts are also handled during loading, so careful, quick handling matters. You will sometimes see claims that DHI grafts grow better; the outcome depends far more on graft handling, planning and the team than on the tool. Some teams combine the two, using DHI at the hairline and classic FUE placement behind it. Our comparison of FUE, DHI and sapphire FUE explains the differences side by side.

How the procedure is carried out#

1. Planning and design. The physician marks the hairline and treatment areas with you.
2. Preparation. The donor area is usually shaved; the recipient area may be shaved or trimmed, or sometimes left longer.
3. Local anaesthesia. You stay awake throughout, with breaks.
4. Extraction. Grafts are removed one by one and kept in a cool storage solution.
5. Implantation. Grafts are loaded into implanter pens and placed directly into the recipient area.
6. Aftercare. The areas are dressed and you receive medication and instructions.

The session often takes most of the day. The number of grafts and the size of the area decide how long it lasts.

Recovery and results#

Recovery is broadly similar to other FUE methods. In the first days, expect redness, tiny scabs and some forehead swelling. Most people have a check-up and first guided wash a day or two after the procedure, before flying home. Transplanted hairs usually shed within the first weeks, new growth begins after a few months, and the result is typically assessed at around 12 months, with the crown often taking longer. See our week-by-week recovery timeline for what is normal at each stage.

Risks and limitations#

DHI is surgery and carries the same risks as other FUE-based procedures, including:

• infection, bleeding and swelling of the forehead or around the eyes;
• folliculitis or small cysts in the recipient area;
• temporary numbness and temporary shedding of existing hair;
• some grafts not growing as expected;
• donor thinning or visible scarring if too many grafts are taken;
• an unnatural hairline if the design or angles are wrong.

Using implanter pens does not remove these risks, and it does not increase the number of grafts your donor area can provide.

Planning your treatment in Turkey#

For a preliminary assessment, send clear photos of your hair from the front, top, crown, sides and back, with dry hair and in good light, plus your medical history and medications. The medical team gives a preliminary graft estimate, which is confirmed after examining you. Our guide on how many grafts you need explains how that estimate is made. If keeping your hair long during healing matters to you, ask whether an unshaved hair transplant is realistic for your case.

After the assessment you receive a written treatment plan and quote. A typical trip covers arrival, the procedure day and a check-up with the first wash before you fly. PSTG coordinates your hotel, airport and clinic transfers, a personal interpreter or assistant, 24/7 support, post-operative medication, follow-up appointments and virtual follow-up once you are home.

Where treatment takes place#

The procedure takes place at a contracted, licensed healthcare institution authorised for international health tourism. Your plan should name the responsible physician and explain who performs each step, including implantation. The physician makes every clinical decision; PSTG, a health-tourism intermediary affiliated with TÜRSAB, coordinates the rest.
