DHI hair transplant
We explain clearly and in plain language how we perform a DHI hair transplant, how it differs from FUE with pre-made channels, and what its limitations are.
What is DHI?
DHI (Direct Hair Implantation) is a form of FUE in which we place the grafts with a pen-like tool called an implanter. It is not a separate method: as in FUE, we take the grafts from the donor area one by one. The difference lies in the placement step.
How does the Choi implanter pen work?
The tip of the pen has a thin, hollow needle. We load the graft into this needle, guide the pen into the recipient area at the angle we have planned, and release the graft into the skin with a plunger.
We use the pen in two ways: to open the channel and place the graft in the same step, or to place the graft into a channel that has already been opened.
The difference between DHI and FUE with pre-made channels
| Step | DHI | FUE with pre-made channels |
|---|---|---|
| Harvesting the grafts | One by one, using the FUE method. | One by one, using the FUE method. |
| Opening the channels | The pen can open the channel and place the graft, or a channel opened beforehand is used. | The channels are opened first; in Sapphire FUE, a sapphire-tipped blade is used. |
| Placement | With an implanter pen. | With fine forceps. |
Both approaches have the same goal. We decide which one to use based on your recipient area and your plan; in some plans, we may also use both together. We describe the approach with pre-made channels on the Sapphire FUE page.
When might DHI be preferred?
Because the pen lets us work between existing hairs, we can also use DHI in long-hair and unshaven hair transplant plans.
Limitations
- Preparing and using the pens requires an experienced team.
Each placement tool has its pros and cons. We decide which one to work with based on these pros and cons, the experience of the doctor performing the procedure, and the plan we make for you.
How do we plan the number of grafts with DHI?
DHI describes how the grafts are placed. The number of grafts you need is set not by the implantation tool but by the size of the area to be treated, the density we aim for and the capacity of your donor area. We determine this number during the examination, as part of planning; there is no fixed number that suits everyone.
We explain what determines the number of grafts in our article how many grafts do I need, and topics such as washing, sleeping and scabs after the procedure on our hair transplant aftercare page.
The process and aftercare
The process is much the same as for other forms of FUE: initial call, examination and planning, the day of the procedure, and follow-up. We harvest and place the grafts under local anesthesia.
In the days after the procedure, you may notice redness, mild swelling or scabbing. We give you written aftercare instructions on washing, sleeping and returning to daily life; follow those instructions.
More about aftercareFrequently asked questions
What is the difference between DHI and Sapphire FUE?
The difference lies in how the grafts are placed. In DHI, we use an implanter pen; in Sapphire FUE, we first open the channels with sapphire-tipped blades. We decide during planning which one suits you.
Can DHI be done unshaven?
In some plans, yes. When grafts need to be implanted between existing hairs, we may choose the implanter pen. We plan separately whether the hair in the donor area needs to be cut short.
Is DHI superior to other methods?
Not in itself. Each placement tool has its pros and cons; the right choice also depends on the experience of the doctor performing the procedure. We determine the technique that suits you during planning.

Leave your name and phone number, and we will get back to you by phone or on WhatsApp. We do not ask for health information or photos in this form.
What happens next?
- We contact you by phone or on WhatsApp to arrange a preliminary consultation at a time that suits you.
- In the consultation, we listen to your expectations and explain the procedure and the process. If photos are needed, we tell you separately how to share them.
- Whether a procedure is suitable for you is decided at the doctor's examination. Fees and dates are discussed after planning.
