The Science of the DHI Method
A high-precision technical exploration of Direct Hair Implantation technology and the proprietary mechanics of the Choi Implanter pen.
Direct Implantation Physics: The ADD Principle
Total control over three critical vectors ensures natural growth results that mimic endogenous hair patterns.
Angle Control
Calculated 360-degree vector control for natural growth patterns. Precision calibrated to match neighboring follicular unit exit angles.
Depth Precision
Micron-level depth management ensuring follicle bulb protection. The depth limiter on the Choi pen prevents dermal over-penetration.
Directional Alignment
Strategic placement mapping for high-density results. Ensures the crown and hairline flow seamlessly with existing hair geometry.
No-Channel Advantage: Microscopic Analysis
Traditional FUE requires pre-created slits (channels) before implantation. DHI combines these into one fluid motion, reducing vascular trauma.
Graft Viability & Cellular Health
Maintaining the physiological integrity of the hair follicle is paramount. DHI protocols minimize "out-of-body" time and environmental exposure.
The DHI Technical Protocol
A step-by-step sterile pipeline designed for maximum efficiency.
01. Extraction
Micron-punch tools isolate follicles with 0.1mm margins.
02. Bio-Storage
Immersion in nutrient-rich HypoThermosol at 4°C.
03. Loading
Grafts loaded into Choi Implanter needles without bulb contact.
04. Placement
Simultaneous incision and implantation via the ADD principle.
