DHI, or Direct Hair Implantation, is a hair transplant technique that is an advanced variation of the Follicular Unit Extraction (FUE) method. DHI is known for its precision and the use of a specialized pen-like instrument, called the Choi Implanter, which allows for direct and controlled implantation of hair follicles without the need for creating recipient sites beforehand.

Key aspects of DHI hair transplant include:

1. Direct Implantation:

   • In DHI, the hair follicles are extracted from the donor area (usually the back of the scalp) using the FUE technique. However, unlike traditional FUE, DHI involves the immediate implantation of each extracted follicle into the recipient area without creating channels or recipient sites in advance.

2. Choi Implanter Pen:

   • The Choi Implanter is a specialized pen-like instrument with a hollow needle attached to it. This tool allows for precise control over the depth, direction, and angle of hair follicle implantation.

3. No Recipient Site Creation:

   • Unlike FUE, where the surgeon creates recipient sites or incisions before implantation, DHI eliminates this step. The Choi Implanter directly implants the follicles, reducing the handling of grafts and potentially minimizing trauma to the scalp.

4. Natural-Looking Results:

   • The direct and controlled implantation with the Choi Implanter aims to create a natural-looking hairline and overall hair distribution.

5. Minimally Invasive:

   • DHI is considered a minimally invasive procedure because it reduces the time the hair follicles are kept outside the body, potentially improving their survival rate.

6. Local Anesthesia:

   • Similar to other hair transplant procedures, DHI is typically performed under local anesthesia, making it more comfortable for the patient.

7. Recovery:

   • The recovery time for DHI is generally comparable to other FUE techniques. Patients may experience some redness and swelling in the treated areas, and these effects are usually temporary.

8. Results:

   • The final results of DHI hair transplant become noticeable as the transplanted hair follicles start to grow. Like other hair transplant methods, the growth is gradual, and full results may take several months.

9. Candidacy:

   • DHI is suitable for individuals experiencing male or female pattern baldness and those looking to restore hair in specific areas.
