The intricate and distinctive structure of curly, coiled, or Afro-textured hair demands surgeons in Dubai and the UAE to employ highly specialized and adapted techniques. Unlike straight hair, where the follicle grows in a straight line, curly hair roots have a curved or spiral growth pattern beneath the scalp. This anatomical variation necessitates a shift from standard procedures to precise, customized methods to ensure the survival of the grafts and achieve a natural aesthetic outcome.

Skilled surgeons in Dubai utilize the following primary techniques and surgical adjustments for curly hair transplants:
1. Tailored Follicular Unit Extraction (FUE) for Extraction
FUE serves as the cornerstone of modern hair restoration, but the conventional method poses a significant risk of cutting the curved follicle in curly hair. Specialist surgeons in the UAE employ a modified FUE approach that prioritizes safeguarding the delicate roots.
A. Use of Specialized Punch Instruments
The main modification lies in the surgical instrument used for extraction:
- Trumpet or Flared Punches: Unlike the sharp, straight-edged punches used for straight hair, specialist surgeons utilize punches with a slightly blunt or trumpet-shaped tip. These tools are designed to carefully navigate around the curved follicle, guiding the extraction process instead of blindly severing it.
- Wider Punch Diameter: A slightly larger punch diameter (e.g., 1.0mm to 1.2mm) may be employed. While this may seem counterintuitive for reducing scarring, a wider bore provides the necessary space to encompass the entire curved root, ensuring the extraction of the follicular unit intact and viable.
- Low-Speed or Manual Extraction: Surgeons often avoid high-speed motorized punches, opting for low-speed motorized or manual FUE techniques to maintain crucial tactile feedback. This enables the surgeon to sense the subtle resistance of the root and adjust the punch angle—a process known as "curl-aware" or "anatomic" extraction—for each graft.
B. Angle and Depth Adjustments
The surgeon's manual dexterity is crucial. While the punch in straight hair follows the hair shaft's exit angle, for curly hair, the surgeon must:
- Anticipate the Subdermal Curve: The surface angle of the hair shaft rarely matches the underlying root angle. The surgeon must anticipate the path of the curve beneath the skin and position the punch accordingly.
- Adjust Punch Depth: Precise depth control is vital. Inserting the punch too deep risks cutting the root, while a shallow insertion results in partial graft removal, rendering it ineffective.
2. Direct Hair Implantation (DHI) for Implantation
Although FUE is the preferred extraction technique, Direct Hair Implantation (DHI) is often favored for the implantation phase of curly hair procedures in Dubai, especially for the hairline and temples.
DHI involves the use of a specialized tool called the Choi Implanter Pen. This pen-like instrument combines creating the recipient site and inserting the graft into a single, highly controlled step.
A. Microscopic Control Over Angle and Direction
For curly hair, the DHI technique offers specific benefits:
- Precise Angle and Curl Alignment: Achieving a natural result hinges on ensuring the new curls align with the native curl pattern. The DHI pen allows the surgeon to precisely control the angle, depth, and exit direction of each follicle, ensuring the transplanted hair lies flat and follows the natural growth swirl, preventing any awkward protrusions.
- Reduced Handling and Trauma: The delicate, curved follicular unit is loaded into the pen and directly implanted. This significantly reduces the time the graft spends outside the body and minimizes handling by forceps, crucial for maintaining the graft's integrity and maximizing its survival rate.
3. Aesthetic Customization and Density Planning
Curly hair transplants require both surgical precision and artistic finesse. The visual density of curly hair is typically higher than straight hair due to the voluminous curls, allowing for specialized aesthetic planning:
- Illusion of Density with Fewer Grafts: Skilled surgeons can create a visually dense appearance with a moderate number of grafts, leveraging the volume of the curl. This approach preserves the donor supply effectively.
- Conservative Hairline Design: Curly hair patterns, particularly in certain ethnicities, often feature straighter, lower hairlines compared to the typical 'M' shape in straight-haired individuals. The surgeon must possess cultural and anatomical awareness to design a hairline that suits the individual's face and curl type naturally.
- Prevention of Keloid Scarring: Given the higher tendency for keloid scarring in individuals with darker skin, the entire procedure—from extraction size to incision placement—is executed with meticulous attention to minimal skin trauma, the most effective measure to prevent keloid formation.
In the UAE, the successful transplantation of curly hair underscores the surgeon's expertise and commitment to these modified techniques. It transcends generic hair restoration to a specialized surgical practice that acknowledges the complex anatomy and unique aesthetic demands of curly hair.
