FUE OR FUT · THE EVIDENCE

FUE or FUT: which keeps more of your hair?

Every clinic has an answer, and it is usually the technique it sells. Here is all the evidence behind it: two small studies, seven patients between them, and they disagree with each other.

01 — WHERE THIS LEAVES YOU

Strip surgery lost the argument without losing a trial.

Many surgeons have stopped offering strip surgery, and most new ones learn only FUE — the 2018 study’s own authors say so. The switch happened without the trial that would justify it. Strip surgery →
FUE is sold under brand names — sapphire, DHI, robotic, suction — and each one changes a single part of the same operation. FUE and its brand names →

02 — THE TWO STUDIES

Seven people, two answers

In 2016 a surgeon in Saratoga Springs, New York put both kinds of graft into marked boxes on the same four scalps, then counted what grew. 86% of strip-harvested grafts grew, against 61.4% of FUE grafts.

Two years later a Minneapolis practice ran the same design on three patients, paid for by the surgeons’ own society. FUE came out about 1% ahead, and the authors wrote that the study was too small to draw any conclusions.

That is the head-to-head evidence. Not a summary of it — all of it.

Each study transplanted both kinds of graft into the same scalps. They point in opposite directions, and neither was randomised.

03 — WHY YOU WON’T FIND THEM

Both sit where medical search cannot see

Both were published in Hair Transplant Forum International, run by the International Society of Hair Restoration Surgery. PubMed does not index it, and the National Library of Medicine does not catalogue it at all.

So when you — or your doctor — search the medical literature for a comparison, nothing comes back. The same search for an ordinary dermatology journal returns thousands.

The surgeons are not outsiders: 8 PubMed records under the 2016 author’s name concern hair. The comparisons simply went somewhere else.

04 — WHAT GETS TESTED

The field runs trials when it wants to

An empty literature can mean a question is too hard to answer. Not this one. In 2021 a Guangzhou hospital randomised 64 men to learn whether trimming the skin off a graft changes how well it grows.

Nobody has randomised a single patient to learn whether the harvesting method does. Put the numbers side by side and the field’s priorities draw themselves.

Nobody ran the comparison. Everybody sells the answer.

05 — A NUMBER TO QUESTION

The 82.7% that belongs to a different operation

If a clinic quotes you a survival rate of 82.7%, ask where it comes from. The likeliest source is a 2025 review in Dermatologic Surgery — of transplants into scarred scalp, after diseases that destroy follicles. Not ordinary hair loss.

And the same review shows survival falling every year after that: 73.3% by two years, 39.6% by four to six. Quoted alone, the first number tells you the opposite of what the review found.

06 — QUESTIONS

What people ask

Is FUE better than FUT?

Nobody knows, because nobody has run the trial. The only two head-to-head studies cover 7 patients between them. One found 86% of strip-harvested grafts grew, against 61.4% of FUE grafts; the other found about 1% more FUE grafts grew.

Does FUE leave less scarring than FUT?

FUE leaves many small round scars instead of one line. Strip scars have been measured in a study of 88 patients; the size of an FUE scar has been measured in 5 patients, at one month.

Which is safer, FUE or FUT?

A 2025 review by researchers at Harvard Medical School and Johns Hopkins, who declared no conflicts, found overall complication rates of 1.2% and 4.7% in two large series. The commonest donor-site problem was raised or keloid scarring after strip surgery, reported in up to 15.1% of patients.

Why do most clinics now offer only FUE?

Not because a trial settled it. The authors of the 2018 study noted that many surgeons have stopped offering strip surgery and most new surgeons learn only FUE. That shift happened without a randomised comparison.

Where can I read the two studies?
