Precise angle control
The implanter pen helps match the natural exit angle and direction of surrounding hair.
DHI places each follicle directly with a Choi implanter pen, helping the surgeon control angle, direction and depth with exceptional precision.

In DHI, harvested follicles are loaded into a fine implanter and placed directly into the recipient area. Unlike classic channel-opening methods, placement and implantation happen in one controlled movement.
This makes DHI especially useful when the goal is a natural frontal hairline, dense placement between existing hairs, or a no-shave option for suitable candidates.
The implanter pen helps match the natural exit angle and direction of surrounding hair.
Ideal for detailed work around the temples, frontal line and visible density zones.
Because graft placement is direct, the recipient area can experience less tissue disruption.
We assess donor density, hair calibre and facial proportions before drawing a conservative, natural hairline.
Follicles are harvested one by one from the donor area and prepared under magnification.
Each graft is inserted with a Choi pen according to the planned depth, angle and density.
You receive washing guidance, recovery rules and follow-up milestones for the first year.
