Implanter pen technique for denser, more precise results.
DHI (Direct Hair Implantation) uses a specialised Choi implanter pen to extract and implant hair follicles directly into the scalp in a single step, without pre-making recipient sites.
This allows our surgeons to control the angle, direction and depth of every graft individually, enabling tighter packing and higher graft survival compared to conventional methods.
Detailed scalp mapping and donor evaluation.
Grafts are extracted and kept viable for immediate implantation.
Grafts are loaded into the Choi pen and implanted directly.
Guided post-procedure care to support healing and growth.
DHI is well suited for patients seeking maximum density in a smaller area, such as the hairline and frontal scalp, and for those who want minimal handling time for extracted grafts.
Actual results vary from person to person depending on scalp condition, donor availability and individual response to treatment. A detailed assessment by our specialists will confirm suitability for you.
