FUE or DHI: which hair transplant technique to choose?

FUE and DHI are the two main families of hair transplant techniques today. They are often presented as rivals, when in fact they share the essentials and are chosen case by case. Dr Khalil El Cadhi, full member of the ISHRS, explains their real differences — and why the “best” choice depends mostly on your situation.

FUE in brief

FUE (Follicular Unit Extraction) means harvesting follicular units one by one from the donor area, then reimplanting them into micro-incisions made beforehand. It is the reference technique, versatile, suitable for most indications. Learn more about FUE.

DHI in brief

DHI (Direct Hair Implantation) uses an implanter pen (Choi type) that makes the incision and inserts the graft in a single motion, with no prior incisions. It offers fine control of angle, direction and depth — useful in areas requiring great precision. Learn more about DHI.

The differences that really matter

The implantation gesture: separate incisions (FUE) versus direct pen implantation (DHI).
Precision on small areas: DHI is often favoured for the hairline, eyebrows or dense touch-ups.
Large surfaces: FUE remains very effective for covering extended zones.
Shaving: both may require shaving, unless you opt for Long Hair FUE.

That said, many beliefs are false: DHI is not “incision-free” (the pen makes one), and neither technique “guarantees” higher density in absolute terms. The quality of the result comes first from the surgeon’s hand and the planning.

What about Long Hair FUE?

Long Hair FUE is a variant of FUE that preserves the length of the harvested hair: the orientation and final look are visible immediately, and the patient leaves with no visible shaved area. It is Dr El Cadhi’s signature technique, especially appreciated by active patients. Discover Long Hair FUE.

So, FUE or DHI?

There is no universal answer. The choice is made after scalp analysis, based on the area to treat, the target density, the donor-area quality and your expectations. Often, both approaches are combined during the same procedure. What matters is that the technique serves your case — not the other way around.

Frequently asked questions

Does DHI leave fewer scars than FUE?
Both leave comparable micro-points in the donor area. Discretion depends mainly on the care taken during harvesting.

Which technique for the hairline?
DHI’s precision is often an asset, but a well-executed FUE also gives excellent results. This is decided in consultation.

Can FUE and DHI be combined?
Yes, frequently: each area receives the most suitable approach.
