What Is DHI?
DHI stands for Direct Hair Implantation. Follicular units are harvested from the donor area at the back and sides of the scalp, then placed into the thinning area using an implanter pen, commonly called a Choi implanter.
The extraction step is the same as standard FUE. The difference is the implantation: with an implanter pen, creating the recipient site and placing the graft happen in one continuous motion, which reduces handling and limits the time grafts spend outside the body.
At HE Clinic this is performed under local anaesthesia by Dr. Dao, our lead hair doctor, with the design matched to your facial proportions, hair characteristics and donor supply.
DHI Compared With Standard FUE
Both relocate healthy follicles from donor to thinning areas, and both avoid a strip scar. The difference is in how grafts are placed.
Neither technique removes a strip of scalp, so neither leaves the long linear scar associated with older FUT strip surgery.
If you would rather not shave, ask about our Long Hair DHI, where existing hair is left in place so you can see the result immediately.
What Actually Happens, Month by Month
Most patients are surprised by the shedding phase, so here is the honest sequence. Transplanted hairs falling out in the first weeks is normal and expected, not a sign the procedure failed.
Transplanted hairs commonly fall out in the first weeks after the procedure. The follicle stays in place, it simply enters a resting phase before producing new hair. This is the stage where patients worry the transplant has failed, so it is worth knowing about before you book rather than discovering it afterwards.

Administered by the doctor. General anaesthesia is not required.
Extraction
Follicular units are harvested from the donor area and held in a controlled environment to protect viability.
Implantation
Grafts are placed with the implanter pen following the planned direction, angle and density.
Recovery and What to Avoid
Possible side effects vary by individual and include swelling, folliculitis, temporary numbness or tingling, uneven growth, and infection, which is rare with proper care. Your doctor will explain the risks specific to your case at consultation.

My transplanted hair is falling out. Has it failed?
Almost certainly not. Shock shedding in the first weeks is normal and expected. The follicle remains in place and enters a resting phase before producing new hair. Growth typically begins around 3 to 4 months, with results visible at 6 months and the full picture at around 12 months.
Will a transplant stop my hair loss?
No, and this matters. A transplant relocates existing follicles, it does not treat the underlying cause. Without a maintenance plan, non-transplanted hair can continue to thin around the new growth. Your doctor will discuss whether ongoing treatment makes sense for you.
Do I have enough donor hair?
Donor supply at the back and sides of the scalp is the main factor determining how much coverage is achievable. It is the first thing assessed. Send clear photos from the front, top, sides and back for an initial view, or come in for a full assessment.
How long does the procedure take?
For around 2,000 grafts, plan on spending most of the day at the clinic. The exact time depends on graft count and case complexity.
Will there be a scar?
There is no long linear scar, since no strip of scalp is removed. Extraction leaves tiny donor micro-wounds that usually heal within days.
Do I have to shave my head?
For the shaven DHI technique, the recipient area is shaved, and a larger treatment area means more shaving. If that does not work for you, Long Hair DHI leaves existing hair in place, so you can see the result straight away.
Who performs the procedure?
Dr. Napasorn Tiwongkum, known as Dr. Dao, is our lead hair doctor. She holds certifications from NHT Turkey, the Korean College of Cosmetic Surgery, and the International Society of Hair Restoration Surgery.
