The Choi implanter, also called the Choi pen, is a specialized pen-type device used to place grafts in hair restoration — most commonly within the DHI (Direct Hair Implantation) approach. It is the best-known type of implanter pen: the graft is loaded into the tip and implanted into the scalp without the need for pre-made channels, so the surgeon controls the angle, depth, and direction of each graft as it is placed.
F.A.Q
The main difference is in the implantation stage. Standard FUE requires creating channels before placing grafts, while the Choi implanter allows direct implantation without pre-made incisions, offering more precision.
Yes, it can improve graft survival by reducing the time follicles stay outside the body and minimizing trauma during implantation.
DHI is the technique, and the Choi implanter is the tool used to perform it. They are closely related but not exactly the same.
Yes, procedures using the Choi implanter are usually more expensive due to the precision, time, and expertise required.
Not always. It is best suited for patients seeking high density and detailed work, while other methods may be better for large transplant areas.
