What is the difference between FUE and FUT? Comparing hair transplant harvesting methods

FUE is a method of harvesting hair follicles (the roots that produce hair) one by one, while FUT is a method of separating hair follicles from a strip of scalp that has been harvested[1]. Beyond just the difference in scarring shape — whether punctate or linear — the choice between them also depends on the area of hair to be shaved, the duration of surgery, and the number of grafts needed (the number of hairs to be transplanted)[2].

How do the harvesting method and scarring differ?

FUE uses a small instrument to harvest hair follicles one by one, so the donor area of the scalp (where hair is harvested) is left with scattered small punctate scars. FUT involves cutting a strip of scalp from the back of the head or similar area and suturing it closed, leaving a single linear scar (scarring).[1].

Is FUE better if you want short hair?

For people who want short hair and wish to avoid linear scarring, FUE may be an easier method to consider[2]. However, since FUE involves harvesting hair follicles one by one under visualization, a wide area of the back and sides of the scalp may need to be shaved[3]. Discussing your desired hairstyle and the area where hair can be shaved with your doctor beforehand will make the decision easier.

Does the choice change if a large number of grafts are needed?

For transplantation over a wide area, the doctor will confirm the density of the donor area (how densely hair is growing) and the amount that can be harvested, then plan the surgery. FUE tends to take longer since hair is harvested from a wide area, while FUT is limited by the width of the strip that can be harvested and the scalp laxity available.[2].

Which method has a higher graft survival rate (the percentage of transplanted hair that takes)?

We cannot say definitively which is higher. In studies directly comparing FUE and FUT graft survival rates, there is still limited evidence strong enough to recommend one method over the other to everyone[1]. Graft survival depends not only on avoiding damage to hair follicles during harvesting, but also on drying and temperature during storage, as well as technique during transplantation[4]. It is important not to decide the outcome based solely on the surgical method name, but to consult thoroughly with your doctor.

Three conditions to compare during consultation

The harvesting method is compared based on your desired hairstyle, the number of grafts needed, donor density, and the condition of your scalp. The consultation will include whether you have had previous scalp surgery and any existing scars, and you will work with your doctor to decide where and how much to harvest from.
