Direct Hair Implantation with the Choi pen — extract and implant in one step.
Direct Hair Implantation (DHI) uses a specialised Choi implanter pen that loads each follicle and places it directly into the recipient area in one motion — no separate channel creation step. This results in less time out-of-body for each graft, potentially higher survival rates, and tighter density control. DHI is RenovaAura's premium hair restoration option, recommended for patients seeking the highest precision.
- Choi pen places follicles directly — less time outside the body
- Highest possible density (up to 70–80 follicles per cm²)
- Best precision for hairline design and eyebrow/beard work
- Premium pricing — typically 30–50% higher than standard FUE
- ◍Patients seeking maximum density and precision
- ◍Hairline-only refinements
- ◍Crown, eyebrow and beard transplants where every follicle counts
- ◍Norwood stage II–IV
What happens, step by step.
Consultation & graft planning
Same as FUE — trichoscopy, hairline design, graft count.
Donor harvesting
Individual follicle extraction under magnification, kept in storage solution.
Loading into Choi pen
Each follicle is loaded into a Choi implanter pen ready for direct placement.
Direct implantation
Surgeon places each follicle at the precise angle, depth, and direction using the pen — no separate slit-making step.
Aftercare
Same protocols as FUE — written guide, day-1 wash demo, photo follow-ups.
Why patients choose this.
Higher graft survival
Follicles spend less time out-of-body, improving viability.
Maximum density
Can achieve 70–80 follicles per cm² — the highest of any technique.
Precision for small areas
Best choice for hairline refinement, eyebrows and beards.
No need to shave fully
Some DHI protocols allow partial shaving — better for women.
