What Is Choi DHI?

Choi DHI refers to the Direct Hair Implantation technique using Choi Implanter Pens, originally developed in South Korea. It's a method that enables surgeons to extract and implant hair follicles directly, one by one, using a pen-like tool that allows for high precision and natural-looking results.

While “DHI” has become a broader brand, Choi DHI specifically emphasizes the original technique and instrument used for implanting grafts — the Choi pen.

How It Works

• Hair follicles are individually harvested using the FUE technique
• Each graft is then loaded into a Choi Implanter Pen, which allows the surgeon to insert it into the scalp at the desired angle, depth, and direction in a single motion
• No need for prior channel creation, which reduces trauma and bleeding

Who It’s For

• Patients who want high-density results, especially in frontal hairlines or temple zones
• People seeking minimal downtime and faster recovery
• Ideal for those concerned with precision, symmetry, and natural hair flow
• Often used in celebrity or high-end procedures where aesthetic detail matters most

Benefits

• Natural hairline design due to precise angle control
• Reduced bleeding and trauma compared to older methods
• Grafts are out of the body for a shorter time, increasing survival rate
• Often allows for unshaven or partially shaven procedures
• Minimal scarring and quick healing

Limitations & Risks

• More time-consuming than standard FUE for large areas
• Requires a highly skilled and experienced surgical team
• Typically more expensive than conventional techniques
• Limited by the availability of Choi pens and surgical expertise

Questions to Ask Your Clinic

• Are your surgeons trained specifically in Choi pen technique?
• How many grafts can be implanted per session using this method?
• Can this be performed without shaving the recipient area?
