DHI Hair Implant (Choi Pen)
The most common approach today, Direct Hair Implantation, briefly known as the DHI technique, is placed individually collected grafts with a unique transplant instrument, the CHOI PEN, which ranges from 0.6 mm to 1 mm thick. The procedure is carried out for other approaches at two distinct stages, unlike with DHI, both with the simultaneous extraction and implantation. Hair shall be cut at a certain length, and the line should be drawn, the grafts are carefully extracted without damage after the optimum angle is determined, and slits found in the area to the implant are made. Unlike the previous ones, no holes or cuts are required for this method, and this process lasts longer compared to them, making it necessary for patient and doctor to be more cautious; the price is also higher due to multi-tools.
- Unshaven operations are possible
- Fast healing
- Healthier hair because grafts are taken and implanted directly
- Dense and lush hair due to the possibility of more root transplants
- No scars remain
- The angles are easily determined
- Physicians and staff are subject to a long-term training period to specialize in the use of this technique.
- In general, it is more expensive than other methods of hair transplantation.
- This approach needs to be given more considerable attention and accuracy during the process.
