DHI (Direct Hair Implantation)

Direct Hair Implantation (DHI) is an application of hair transplantation, the surgical technique in which hair follicles are moved from a donor site to a recipient site to treat hair loss, most often male pattern baldness. It is a form of follicular unit extraction (FUE), in which the donor follicles are removed one at a time as individual follicular units and then implanted into the thinning or balding area of the scalp. Because hair naturally grows in groupings of one to four hairs, modern technique harvests and transplants these follicular units in their natural groupings and sets them at an angle that mimics the original hair orientation, so the restored hair looks natural. Before surgery the surgeon analyses the scalp, may measure its laxity with a laxometer and its existing density with folliscopy, discusses the patient's expectations, and advises whether one or several sessions will be needed; some patients also use topical minoxidil and vitamins beforehand. The operation is usually performed on an outpatient basis under injected local anaesthesia, with optional mild sedation, and the donor area is shampooed and treated with an antibacterial agent before harvesting. Careful, atraumatic extraction that avoids transecting, or cutting, the follicle is important for the viability of the transplanted hair, and post-operative antibiotics are commonly prescribed to help prevent wound or graft infection. Temporary shedding of hair, known as shock loss, is a common and usually temporary side effect.

DHI is typically priced 20-40% above FUE at the same clinic due to higher consumables cost and longer implantation time. Pricing models vary — some clinics charge per-graft, others per-session. Verify exactly which grafts are included, whether donor-area trichophytic closure (if any) is included, and whether post-operative medications (antibiotics, finasteride, minoxidil) are included.

Day 0: procedure completed in 6-9 hours under local anaesthesia. Bandaged donor area, antibiotic ointment. Patient may sleep semi-upright that night.

Days 1-7: peak swelling around forehead and eyelids (resolves by day 5-7). Saline-based gentle rinsing of recipient and donor areas from day 2-3. Avoid touching grafts. Sleep with head elevated for 3-5 nights.

Day 10-14: crusts separate naturally with continued gentle washing. Many patients return to social activity. Graft 'shock loss' begins around weeks 2-4 — transplanted hairs shed, leaving the follicles in place to grow new hairs later.

Month 1-3: dormant phase. The transplanted follicles remain in place but produce no visible hair.

Month 4-6: new growth begins. First hairs are typically fine and may be lighter in colour; they thicken over the following months.

Month 9-12: substantial growth visible. Most density at 12 months.

Month 18: final density and styling potential. Long-term care includes ongoing medical therapy (minoxidil, finasteride) to slow native hair progression.

DHI is one of the most-marketed hair-transplant techniques in the Turkish medical-tourism sector. The branding can obscure substantial variation between providers — some clinics performing 'DHI' use only one or two Choi pens for a portion of the session and a forceps for the rest, while others use Choi pens for the full implantation. International patients should specifically verify what the clinic provides, who actually performs the implantation, and the lead surgeon's involvement in the procedure.

In-country stay and recovery are identical to FUE — typically 3-5 days locally before flying. Post-operative crusting management is the same.
