Hair transplant techniques: FUT, FUE and DHI explained honestly

A hair transplant is precision surgery, not a cosmetic quick fix.

Below we explain — from clinical reality, not from sales talk — which hair transplant techniques exist, why the older methods are outdated, and why our doctor today works exclusively with DHI. We first explain what a graft actually is: a natural cluster of one to four hairs from the donor area.

№1

First things first: what exactly is a graft?

To understand the techniques, you need to know what is actually being moved. The scalp is not a flat, even surface but a complex tissue of blood vessels, nerves and thousands of small clusters of hair.

Hair doesn't grow one by one, but in natural clusters of one to four hairs. Such a cluster — together with its sebaceous gland, a small muscle and a nerve ending — is called a follicular unit, commonly a graft. During a transplant we move these grafts from the donor area (the back and sides of the head, where hair is genetically resistant to loss) to the recipient area (the bald or thinning zones).

Every detail counts: the angle at which a hair grows, the direction, the depth and the mutual density determine whether the result looks natural. That is why this is microsurgery under magnification — not a treatment you carry out on routine.

The techniques, from old to new

DHIDirect Hair Implantation

The newest evolution

DHI is not a completely different procedure, but a direct evolution of FUE. The harvesting is identical (individual, with the punch). The difference lies in the placement: with a special Choi implanter pen, each graft is loaded and placed in a single motion, without any channels being cut open beforehand.

Surgical advantages

Less tissue damage to the scalp: the separate cutting of channels disappears, so less trauma and less bleeding.
Maximum control over the angle, direction and depth of each hair.
Higher density possible, without damaging existing hairs.
The grafts spend less time outside the body, which benefits their survival rate.

Point of attention

Technically more demanding and labour-intensive — it stands or falls with an extremely experienced team.

FUEFollicular Unit Extraction

Gold standard

FUE was the breakthrough. Instead of cutting out a strip, the grafts are harvested one by one from the donor area with a micromotor and an extremely fine punch (0.7–1.0 mm). They are then placed in the recipient area — with classic FUE, into micro-channels made beforehand.

Advantages

No sutures and no linear scar — only microscopic dots that are virtually invisible, even with short hair.
Minimal invasiveness and fast tissue recovery.
Flexibility: the doctor can specifically select the strongest grafts, spread across the donor area.
More comfort, less post-operative pain and a lower risk of complications.

Point of attention

With classic FUE the channels are cut open first and only then are the grafts placed — this is exactly where DHI takes the next step.

Thanks to these advantages, FUE became the worldwide gold standard for harvesting grafts. Virtually every modern procedure — including DHI and Sapphire — builds on this FUE principle.

FUTFollicular Unit Transplantation (strip method)

Outdated

In FUT, a narrow strip of scalp is cut from the donor area. That strip is divided under the microscope into individual grafts, and the wound is closed with sutures.

Advantages

High graft survival rate: they remain protected in the tissue until just before placement.
Efficient for harvesting many grafts in one go.

Clinical drawbacks

A permanent, linear scar across the back of the head.
A longer recovery and more post-operative pain due to the sutured wound.
Not suitable for those who wear their hair short.

It is precisely because of that visible scar and the heavier recovery that patients rarely choose this technique today, even though it is medically sound in itself.

Why our doctor works exclusively with DHI

Our doctor has made a clear choice: today he works only with the DHI technique. Not because it sounds newer, but for purely clinical reasons — and the most important of these is preserving the scalp.

With classic FUE, the channels in the recipient area are cut open first, after which the grafts are placed into them separately. With DHI, this happens in a single motion with the Choi pen. The result: fewer incisions, less trauma and less bleeding in the recipient area, and therefore a smoother recovery. At the same time, the pen determines exactly the angle, direction and depth of each hair — precisely what you need for a natural hairline and a high, even density.

Honestly: the technique is only a tool

This is the part an honest surgeon always adds. FUE or DHI — the technique is ultimately just a tool. The real difference lies in the hand that holds it. A successful transplant stands or falls with the expertise of the doctor and the team:

The planning of the hairline.

A natural hairline takes into account your age, the shape of your face and your future hair loss — not just what you want today.

The extraction ratio and the donor area.

Taking too many grafts from one zone (overharvesting) permanently damages the donor area. An experienced doctor harvests spread out and with restraint.

The transection ratio.

That is the proportion of grafts damaged during harvesting. A strong team deliberately keeps this low, so that as many hairs as possible actually grow.

The angle and depth of implantation.

Decisive for the growth direction and therefore for a result that looks truly natural.

That is why NIVA CARE deliberately chooses one fixed, experienced doctor rather than the cheapest or fastest option. The Choi pen is nothing without the surgeon who holds it — and that is exactly what we stand for: pure quality and transparency.

Capacity per session

With DHI, our doctor places up to 4.500 grafts in a single session. Enough to tackle more extensive zones in one procedure too — with the precision and the care for the scalp that DHI brings.

In short

FUT (strip): high graft survival, but a permanent linear scar — rarely chosen today.
FUE: harvesting grafts individually, virtually invisible dot scars — the worldwide gold standard.
DHI: the evolution of FUE, with direct implantation via the Choi pen. Less scalp damage and maximum control. This is what our doctor uses.
