FUE vs FUT vs DHI: Which Hair Transplant Method?

FUE (follicular unit extraction) is a hair transplant technique in which individual follicular units are removed one by one from the donor area with a small punch and implanted into thinning areas.

FUE, FUT and DHI are the three terms you will meet most often when researching hair transplants. Clinics sometimes market them as if one is clearly better, but each has strengths and trade-offs. This guide explains how they work, how they compare, and how surgeons decide which to use.

FUE: follicular unit extraction

In FUE, the surgical team removes individual follicular units (natural groups of one to four hairs) from the donor area using a small circular punch, usually under 1mm wide. Recipient sites are then made in the thinning area with fine blades or needles, and the grafts are placed into them.

Pros: no linear scar, quicker donor healing, and the option to wear hair short at the back afterwards. Cons: the donor area is usually shaved, extraction is time-consuming, and over-harvesting can thin the donor area if not planned carefully. FUE is now the most common technique in London clinics.

FUT: follicular unit transplantation (strip)

In FUT, the surgeon removes a thin strip of skin from the back of the scalp, closes the wound, and the team divides the strip into individual grafts under microscopes. Grafts are then implanted in the same way as FUE.

Pros: can yield a large number of high-quality grafts in one session, and the donor hair does not need shaving. Cons: leaves a linear scar, which is usually hidden by hair but visible with very short haircuts, and the donor area can feel tight for a while. FUT has become less common but is still used, particularly where large graft numbers are needed or to preserve FUE capacity for later.

DHI: direct hair implantation

DHI is a variation of FUE. Grafts are extracted in the same way, but instead of making recipient sites first, the surgical team loads each graft into a pen-like implanter (often called a Choi pen) that creates the channel and places the graft in one movement.

Pros: precise control over angle and direction, useful for hairlines and for adding density between existing hairs, and often possible without shaving the recipient area. Cons: slower per graft, which usually means a higher price and longer sessions. One London clinic charges about £900–£1,200 more for DHI than standard FUE at the same graft limit.

Side-by-side comparison

Which gives the best results?

There is no single best technique. Graft survival and how natural the result looks depend mainly on the team’s skill, how carefully grafts are handled, the design of the hairline, and whether the plan accounts for future hair loss. A well-performed FUE and a well-performed DHI can produce very similar results; a poorly performed procedure of either kind will disappoint. Be wary of clinics that claim their branded technique guarantees better growth.

How do surgeons choose a technique?

A surgeon will consider your donor density and hair characteristics, the size of the area to be treated, whether you want to keep your hair long or short, the condition of any previous transplant scars, and your budget. Some patients have a combination: for example FUT for a large first session and FUE later.

Questions to ask about technique

• Which technique do you recommend for me, and why?
• Who performs the extraction, the incisions and the implantation?
• How many grafts do you plan to take, and how much donor reserve will I have left?
• Will you need to shave my head?
• What are the scarring and recovery differences for me specifically?

Does the technique change the cost in London?

Technique affects price, but graft count matters more. In London, published prices range from about £3,199 for a fixed FUE package to £11,900 for a large Harley Street session. See our hair transplant cost guide for a full breakdown.

What about FUE with sapphire blades, or “robotic” FUE?

You will also see terms such as sapphire FUE, micro FUE and robotic FUE. These describe the instruments used for parts of the procedure, such as sapphire-tipped blades for making recipient incisions or a robotic system to assist extraction. They can be useful tools, but they are not separate techniques with guaranteed better outcomes. Ask the clinic what difference the tool makes for your case, and remember that planning, graft handling and the experience of the team still matter most.

Combining surgery with medical treatment

Whichever method you choose, a transplant does not stop your existing hair from thinning. Many surgeons recommend a long-term plan that may include medical treatment to slow further loss, so the transplanted hair does not end up isolated as surrounding hair recedes. Discuss the options, benefits and side effects with a doctor.

Next steps

The best way to find out which method suits you is an assessment by a GMC-registered surgeon. You can request a hair assessment from a vetted, CQC-registered London clinic, or read more about hair transplants in London.
