FUE vs FUT vs DHI: Which Method, and How Many Grafts You Need

Choosing a technique feels like the big decision, but the choice that matters more over a lifetime is how your limited donor hair is used. This guide explains the three methods, how graft numbers are worked out, what to do if your donor area is thin, and what happens on the day of surgery.

Which hair transplant method is better: FUE, FUT or DHI?

None is better for everyone. All three move the same thing, follicular units of one to four hairs from the back and sides of the head, and each has a trade-off.

• FUT (strip): the surgeon removes a thin strip of scalp from the back of the head, closes the wound with stitches and divides the strip into grafts. It leaves one linear scar, hidden by longer hair but visible with a very short cut.
• FUE: grafts are taken out one by one with a small punch, leaving many tiny dot scars spread over the donor area. You can usually wear the back shorter, though some scarring can show with a very close shave.
• DHI: a version of FUE in which each graft is loaded into a pen-like implanter and placed directly, instead of the surgeon making all the recipient sites first. Harvesting is the same as FUE.

FUE is now the dominant method. In the ISHRS 2025 practice census, FUE harvesting was used in 85.4% of procedures in men and 68.2% in women performed by member surgeons in 2024. Recovery differs a little: ISHRS patient pages suggest at least one week off work for FUE and two weeks for FUT, and the NHS says FUT stitches come out after 10–14 days.

The real debate is between FUE and FUT when hair loss is advanced and the surgeon wants to get as many grafts as possible over a lifetime. Some surgeons recommend FUT in that situation, and some patients later regret the scar. Ask each surgeon how their method would affect a second session and the haircuts you could wear afterwards.

How many grafts do you need for a hair transplant or a new hairline?

A typical first session is a little over 2,000 grafts, but your number depends on the area, the density you want and what your donor area can spare. The ISHRS 2025 census found that member surgeons placed an average of 2,347 grafts in a first procedure and 1,637 in later ones in 2024.

A hairline on its own needs fewer grafts than a hairline plus mid-scalp, and the crown needs more than people expect because it is a large, curved area. Hair character matters as much as the number: thick, coarse or curly hair covers more scalp per graft than fine, straight hair. That is why two people with the same pattern can get very different quotes.

Units are a trap when comparing quotes. Clinics in the US, the UK and Turkey count grafts, which roughly equal follicular units. Private chains in China also charge per follicular unit, but one public hospital in China has published its price per single hair, and Shanghai's new price item counts one session as a base of 100 follicular units plus extra units. Ask every clinic which unit it is quoting, and whether the count in the price is a guaranteed minimum or an upper limit.

Is a hair transplant realistic if your donor area is limited?

Often yes, but with a smaller goal. When the donor area is thin, the usual approach is to put grafts where they frame the face, usually the front, and accept less coverage behind. A transplant moves hair; it does not create more, so every graft used now is one less for later.

Donor capacity can only be judged in person, by checking density under magnification. Photos mislead, because lighting and hair length change how thick the back looks. Beard and body hair are sometimes used as extra donor hair in advanced cases, mostly to add density to the crown, but they grow differently from scalp hair and not every surgeon offers it.

Medication changes the maths too. Keeping the hair you have means fewer grafts are needed now and more are left in reserve. In the ISHRS 2025 census, member surgeons said they always or often prescribe oral finasteride 1 mg (72.3%) and oral minoxidil (64.7%), although oral minoxidil is off-label for hair loss. Finasteride carries UK MHRA warnings about sexual side effects, depression and suicidal thoughts, strengthened in May 2026, so it is a decision to make with a doctor.

What does the procedure involve, and who should do the incisions?

On the day, you and the surgeon agree the hairline, the scalp is numbed with local anaesthetic, grafts are harvested, recipient sites are made and the grafts are placed. The NHS says it usually takes one day and you go home the same day.

Who does each step matters. ISHRS describes black-market clinics as places where unlicensed, non-doctor technicians perform the surgery illegally. In its 2025 census, 59.4% of member surgeons said such clinics operate in their city, and repairing their work made up an average of 10% of members' cases. Ask in writing who will design the hairline, who will harvest, who will make the incisions and who will place the grafts.

China sets a clear bar on paper. Under the national rules for aesthetic medical services, the clinic must hold a medical institution licence, and the doctor leading aesthetic surgery must be a registered physician with at least six years of clinical work in aesthetic or plastic surgery. The National Health Commission runs an online register of institutions and doctors. It may not load from outside China, so ask the hospital to send the licence and the lead doctor's registration details before you book.

How long until the grafts are secure, and does the method change that?

The first days are the fragile period for every method. Crusts form within 24 hours and usually fall away around 4–14 days after surgery, according to ISHRS patient pages, and until then the grafts should not be rubbed or knocked. Many patients sleep on their back with the head raised, using a travel pillow so the grafts do not touch anything. FUT adds stitches that come out at 10–14 days. Washing advice alone ranges from day 2 at Cleveland Clinic to day 6 on the NHS website, so follow your own surgeon's written protocol rather than general rules.
