Ear, Nose & Throat: what to know before you go

What this guide covers

If you've spent more than 20 minutes researching a hair transplant, you've already met three names: FUE, DHI, and Sapphire FUE. Every clinic uses these terms, every clinic claims theirs is best, and the marketing pages tend to make them sound like different operations. They're not. They're three variations of the same procedure, with real but small differences. This guide is the version I wish every prospective patient read before their first consultation.

What FUE actually is

All three techniques are variations of Follicular Unit Extraction — a method, established commercially in the early 2000s, of removing individual hair follicles from a “donor area” (typically the back and sides of the scalp, where hair is resistant to genetic thinning) and re-planting them in the area where you've lost hair.

The technique replaced an older approach called FUT (Follicular Unit Transplantation), which involved taking a long strip of skin from the back of the head. FUT left a linear scar that ruled out short hairstyles. FUE doesn't. By 2026, FUT is essentially extinct for cosmetic patients.

FUE vs DHI vs Sapphire FUE — the actual difference

The three terms describe two things that vary: how the recipient channels are made, and how the grafts are placed into them. The extraction step — the actual harvesting from the donor area — is essentially the same across all three.

The technique matters. The surgeon matters more. A good surgeon doing FUE will out-result a mediocre surgeon doing DHI, every time.

Classic FUE uses a steel blade to cut tiny incisions in the recipient area, after which the grafts are placed using fine forceps. Channel diameter sits around 1.0 mm.

Sapphire FUE changes the steel blade to a sapphire-tipped one. The cut is slightly smaller (~0.7 mm), which means crusts shed a few days earlier and the channels heal a touch less visibly. Same forceps placement. Same extraction. Same everything else.

DHI (Direct Hair Implantation) skips the separate “make the channel” step entirely. Instead, the surgeon uses a Choi implanter pen — a hollow needle pre-loaded with a graft — to make the incision and place the graft in a single motion. The advantage is precision: angle and density control are unmatched. The trade-off is speed — DHI is slower per graft, so single-session caps are typically 3,500–4,000 grafts rather than 4,500–5,000.

Side-by-side comparison

Which is right for you

The honest decision tree is shorter than most clinics make out.

• If you have widespread thinning (Norwood IV–V) and a normal hair pattern: Sapphire FUE. Faster healing, indistinguishable result, almost always the same price as classic FUE now.
• If your concern is hairline design or you have diffuse thinning in a small area: DHI. The precision advantage shows here, especially for women with diffuse thinning where existing hair must be preserved.
• If you can't take 2 weeks of visibly shaved-head time: unshaven FUE (a variant of any of the above). Typically €300–€800 premium because it's slower.
• If you're undecided after reading this: book free video consultations with two surgeons (one offering FUE, one offering DHI) and ask each what they'd do in your case. The answer that includes “and here's the trade-off” is the right surgeon, regardless of technique.

What's marketing, what's medicine

Three claims you'll see in clinic marketing that don't hold up under scrutiny:

“DHI is the newest technique.” Direct implantation has been around for over a decade. The Choi pen was developed in Korea in the late 1990s. It's not new; the marketing language is.

“Sapphire blades cause no scarring.” Smaller channels heal slightly less visibly. They still heal — and any micro-scar is the same as a steel-blade channel after 6 months. Sapphire reduces the visibility during the first 7–14 days; that's the real benefit.

“Robotic FUE is more precise than human surgeons.” ARTAS and similar systems are useful for high-volume extraction support. They do not replace the surgeon's design decisions and they do not, in 2026, deliver better aesthetic results than an experienced surgeon working manually.

10 questions to ask any surgeon

1. How many of my exact procedure variant have you performed personally?
2. Can I see five before/afters of patients at my Norwood stage?
3. How many grafts do you recommend for my case, and why not more?
4. Will you personally make every incision, or do technicians?
5. What's your recommended technique for my case, and why?
6. What's your complication rate over the last 12 months?
7. What's included in your aftercare programme for the first 12 months?
8. Can I have a video call with you before I fly?
9. If I need a revision, what does that cost — and when?
10. If you were in my position, would you do this procedure now?
