Choi Pens: A Revolution in Hair Transplantation with DHI Technique

In the ongoing pursuit of perfection and beauty, achieving thick, healthy hair remains a dream for many individuals facing hair loss or baldness. With the remarkable advancements in aesthetic medicine, hair transplantation has emerged as a definitive and effective solution. Among the latest and most precise techniques, Direct Hair Implantation (DHI) using the Choi Pens stands out as a breakthrough, offering unmatched natural results and density.

This detailed guide takes you on a journey through everything you need to know about Choi Pens for DHI hair transplant—from their intricate working mechanism, unique advantages, and results—providing you with a clear, comprehensive view of this revolutionary approach to hair restoration.

What Is the DHI Hair Transplant Technique?

Direct Hair Implantation (DHI) is the most advanced version of the Follicular Unit Extraction (FUE) technique. While traditional FUE involves two separate steps—extracting hair follicles and then creating channels in the recipient area for implantation, DHI merges these into a single, highly precise step using a specialized tool known as the Choi Implanter Pen.

The core concept of DHI lies in the immediate, direct implantation of extracted follicles into the recipient area without the need for prior incisions or channel openings. This significantly reduces the time follicles spend outside the body, increasing their survival rate and ensuring successful growth.

What is Choi Pen?

The Choi Implanter Pen is a precision surgical instrument resembling a pen, originally developed at Kyungpook National University in South Korea. It features a hollow needle at its tip, typically ranging from 0.5 to 1.5 mm in diameter, specially designed to accommodate different follicle sizes.

How does the Choi Pen work?

The entire procedure is executed with exceptional precision by a team trained specifically in using this tool:

• Follicle Loading: A technician or nurse carefully loads an extracted follicle into the pen’s hollow needle.
• Handover to the Surgeon: The loaded pen is handed over to the surgeon.
• Direct Implantation: The surgeon inserts the needle into the scalp at a predetermined angle, depth, and density, then presses the pen’s plunger.
• Follicle Release: Pressing the plunger gently releases the follicle into its new position in the scalp.
• This meticulous process is repeated for each follicle, typically using 2 to 6 Choi Pens per session to maintain efficiency.

Advantages of the Choi Pen

The Choi Pen offers several benefits over traditional hair transplant techniques:

• No need for creating channels in the scalp, reducing pain and trauma.
• Follicles are implanted with high precision, respecting hair characteristics such as depth, direction, and angle of growth.
• Shorter procedure time and reduced follicle handling increase survival rates and final results.
• Minimal scarring and fewer side effects, leading to faster recovery and earlier visible results.
• Lower risk of complications such as bleeding compared to traditional incision-based methods.
• Particularly suitable for patients with bleeding disorders or diabetes.
• An excellent choice for hair transplantation without shaving (especially for women), as well as for delicate areas such as the frontal hairline, eyebrows, eyelashes, beard, and mustache.

Pre-Procedure Instructions for DHI with Choi Pens

Before undergoing DHI, patients go through consultation and preparation phases to determine suitability:

• The physician evaluates the patient’s cosmetic goals, cause of hair loss, and pattern of thinning.
• The scalp, hair density, and balding area are assessed to calculate the required number of grafts.
• Blood tests and general health evaluations are performed to rule out medical issues.
• Patients are advised to stop taking blood thinners at least two weeks before and after the procedure.
• Smoking and alcohol should be avoided, as they interfere with medications and tissue healing.

Steps of the Choi Pen Hair Transplant

Hair transplantation using Choi Pens involves a series of organized stages to ensure optimal results:

Step 1: Consultation and Planning

The doctor assesses the patient’s condition, baldness level, and donor area density (usually at the back of the head). A new hairline is drawn, and the required number of follicles is estimated to achieve the desired density, considering facial features and patient expectations.

Step 2: Preparation and Follicle Extraction

The donor area is shaved and numbed with local anesthesia for complete patient comfort. Hair follicles are extracted individually using a micromotor, just like in FUE. These follicles are examined under a microscope, sorted based on the number of hairs per graft, and preserved in a special solution to maintain viability.

Step 3: Direct Implantation with Choi Pens

The recipient area is locally anesthetized. The medical team loads follicles into Choi Pens and implants them directly into the designated areas. This step gives the surgeon complete control over:

• Implantation Depth: Ensuring follicles are placed at the correct depth for healthy growth.
• Angle of Insertion: Matching the natural angle and direction of existing hair for a seamless look.
• Density Distribution: Allowing for high-density implantation and excellent coverage.

Post-Procedure Recovery

Although the Choi Pen reduces discomfort and side effects, patients should follow post-transplant care instructions:

• Avoid washing the scalp for the first 3 days, then follow physician-guided washing instructions.
• Do not expose grafts to direct tap water pressure or hot water. Avoid excessive heat in general.
• Sleep on the back with pillows to reduce facial swelling; avoid sleeping on the transplanted area for several weeks.
• Avoid strenuous activity, exercise, and travel for a short recovery period.
• Keep the scalp clean and protected; head coverings can be used after about 10 days with soft, loose caps.

Expected Results of DHI with Choi Pens

• Transplanted hair sheds after about 3 weeks.
• Follicles heal within 2–3 weeks.
• New hair growth usually begins around the 3rd month.
• By the 6th month, most of the scalp is covered.
• Final results appear between 12–18 months after the procedure.
