The DHI-Choi technique is a specialized method used for hair transplantation. This technique involves the use of a specific pen-like instrument known as the Choi pen. This pen is utilized for both extracting individual hair follicles and implanting them.

The process of DHI-Choi hair transplantation generally includes the following steps:

1. Extraction of hair follicles: Hair follicles are individually extracted using the Choi pen.

2. Implantation of hair follicles: The harvested hair follicles are directly implanted into the areas affected by baldness using a special technique.

This technique does not require the creation of channels because the hair follicles are implanted directly using the specialized pen. As a result, the recovery process might be faster, and there might be a lower likelihood of leaving noticeable scars. However, it’s important to note that the expertise of a skilled surgeon is crucial for this technique as well.
