Three Techniques, One Goal

FUE, DHI, and Sapphire FUE all move healthy follicles from a donor area (usually the back and sides of the scalp) to areas of thinning or baldness. The surgical outcome depends less on which acronym you pick and more on the surgeon’s hand, the team’s planning, and the aftercare you get.

That said, there are real technical differences. Here is what actually changes between the three.

Graft Extraction Is the Same

Every modern transplant starts the same way: individual grafts (each containing 1–5 follicles) are removed from the donor area one by one with a small punch — typically 0.7 to 1.0 mm in diameter. This extraction step is identical whether you book FUE, DHI, or Sapphire FUE.

Where the techniques diverge is in the implantation step — how the grafts are placed into the recipient area.

Classic FUE: Channels, Then Grafts

In classic FUE, the surgeon first creates hundreds or thousands of micro-incisions (channels) in the recipient area with a fine steel blade. A technician team then places a graft into each pre-made channel.

This is a two-step, parallel workflow. It scales well for large sessions (3,000+ grafts in a day) and lets the surgeon fully design the hairline and density map before any grafts go in.

Sapphire FUE: Finer Blades, Tighter Density

Sapphire FUE is identical to classic FUE except the steel blade is replaced with a sapphire-tipped blade. The sapphire creates smaller, smoother channels, which means:

• Less tissue trauma — faster crust formation and healing
• Tighter graft spacing is possible, so visual density can be higher
• Reduced post-op swelling for most patients

DHI and the Choi Implanter Pen

DHI (Direct Hair Implantation) replaces the "channel + place" two-step workflow with a single tool: the Choi implanter pen. The surgeon loads one graft into the pen and implants it directly in one motion — no pre-made channel.

Advantages: precise control over angle and depth, minimal time between extraction and implantation (better graft survival), and the ability to work on unshaven areas. DHI is especially popular for hairline refinement and for women who do not want a fully shaved scalp.

Which Technique Suits Which Case

There is no universally "best" technique. What matters is matching the method to your:

• Norwood stage and total grafts needed
• Donor area capacity and density
• Whether you need hairline design, density fill, or both
• How much downtime you can afford (Sapphire and DHI typically recover fastest)
• Whether you want to shave or keep your existing hair

What Happens at Intake

At VANC we begin with a free intake in Belgium or the Netherlands. We assess your donor capacity, hair loss pattern, and goals, then recommend the technique that best fits your case. From there, we coordinate the surgical procedure with our trusted partner team abroad, and handle your monthly aftercare back here at the clinic once you return home.
