The terminology around hair transplant techniques causes more confusion than it should. FUE, FUT, DHI — these three abbreviations come up in every initial conversation we have, and patients frequently arrive at consultation with incorrect assumptions about what they mean and which one they need.
Let me set it out clearly, without the marketing language that surrounds most of these discussions.
The Two Parts of Any Hair Transplant
Every hair transplant, regardless of technique, has two phases: extraction and implantation.
Extraction is how follicles are removed from the donor area. Implantation is how they are placed into the recipient area. The three techniques differ in how one or both of these phases are performed.
FUE: Individual Extraction, Separate Implantation
FUE — Follicular Unit Extraction — removes individual follicular units from the donor area one at a time using a fine circular punch tool. The punch is typically 0.75 mm to 0.85 mm in diameter.
Each extracted unit is held in a solution while the rest of the extraction is completed. Once enough grafts have been collected, recipient sites are created in the thinning area, and the grafts are placed into those sites individually.
FUE is the most widely used technique for a reason: it works very well across the broadest range of cases. It leaves multiple small round healing points in the donor area rather than a linear scar, which means patients can wear their hair at a grade 3 or above without any visible evidence of having had a procedure.
The limitation of FUE is that individual follicle selection is done at the point of extraction, which requires the donor area to be trimmed short enough for the punch to reach the follicle accurately.

FUT: Strip Excision, Microscopic Dissection
FUT — Follicular Unit Transplantation — is the original technique. A strip of scalp is excised from the donor area and the wound closed with sutures. The strip is then dissected under magnification by the surgical team, who identify and separate individual follicular units from the tissue.
Those units are implanted in the same way as FUE.
The significant advantage of FUT is that dissection under magnification allows the team to identify every viable follicular unit within the strip, including those that FUE extraction might miss or transect. For patients who need the maximum possible graft yield from a single session, FUT can deliver a higher count.
The obvious trade-off is the linear scar. This heals to a fine pale line in most patients, but it is visible if the back of the head is shaved completely. FUT is therefore not suitable for patients who routinely wear their hair very short at the back.
FUT is also the preferred technique for patients who cannot or will not shave the donor area — the strip is taken from beneath the surrounding hair, which covers the site during healing. This makes it the standard for many female patients and for some transgender patients who prefer not to shave.

DHI: Individual Extraction, Direct Implantation
DHI — Direct Hair Implantation — extracts follicles in exactly the same way as FUE. The difference is entirely in how those follicles are placed.
In FUE, recipient channels are created first and grafts are placed into them as a separate step. In DHI, a Choi Implanter Pen is used to carry out channel creation and graft placement simultaneously. The graft is loaded into the pen and implanted directly into the scalp without a pre-made channel.
The advantage of this combined step is precision and the avoidance of pre-made channels. This matters most in one specific situation: adding density to an area where some hair already exists.
When existing hair is present in the recipient area, creating recipient channels first (as in FUE) risks damaging those native follicles. The direct implantation of DHI significantly reduces this risk. For patients with crown thinning who still have native hair they want preserved, or for patients who want increased hairline density without disturbing existing follicles, DHI offers a meaningful advantage.
For cases where the recipient area is largely bare — a full hairline reconstruction, for example — the advantage of DHI over FUE is minimal, and FUE is typically the more efficient choice.

Which One Is Right for You?
The answer depends on your specific situation.
If your donor area is healthy, you can shave it for the procedure, and you want the most widely proven technique for scalp restoration: FUE.
If you cannot shave the donor area, need maximum graft yield in a single session, or are a woman or transgender patient who prefers not to shave: FUT.
If you are adding density to an area with existing hair and want to avoid disturbing those native follicles: DHI.
Many cases involve combining considerations. A patient might want DHI for the crown density work and FUE for the hairline. These decisions are made at consultation, where your surgeon can examine the actual situation rather than advising from a form.
