DHI: Direct Hair Implantation
DHI (Direct Hair Implantation) extracts and implants hair follicles in a single step using a pen-like tool called a Choi pen, without pre-made incisions. It gives surgeons precise control over angle, depth, and density, producing a natural hairline with no linear scarring.
How It Works
About DHI (Direct Hair Implantation)
DHI is the most advanced hair restoration technique available today. Hair follicles are implanted directly into the scalp using a precision implanter pen: no pre-made incisions, no scalpel, no stitches.
This gives surgeons exact control over the angle, depth, and density of every graft, resulting in a natural hairline design with no visible linear scarring.
Benefits
- No cuts, no stitches, no linear scar: a pen-like tool is used instead of a scalpel
- Higher graft survival rate than traditional FUE, since extraction and implantation happen as one step
- Precise, natural-looking hairline design with fine control over graft angle and depth
- Minimal downtime: most patients return to non-physical work within 5โ7 days
How It Compares
FUE involves extracting grafts and manually creating recipient sites before implantation. DHI uses a specialized pen (Choi pen) to extract and implant grafts simultaneously, allowing greater precision and density without pre-made incisions. DHI is generally recommended for hairline design and higher density; FUE can cover larger areas more quickly.

FAQ
DHI (Direct Hair Implantation) FAQ
Neither is universally "better." They suit different cases. DHI is generally recommended for hairline design and higher density since it doesn't require pre-made incisions. FUE can cover larger areas more quickly. Your surgeon recommends one based on your graft count and goals during your consultation.
