Up to 80% of men and 42% of women have hair loss, which is an unpleasant problem that affects a significant section of the population. For both sexes, the possibility of developing hair loss increases with aging. Although there are several reasons why people lose their hair, androgenic alopecia (AGA), an androgen-sensitive pattern of hair loss that affects both men and women, is by far the most common reason[1].

A natural-looking hairline with sufficient density must be developed for hair transplantation to produce the required outcome. There are many variations on the techniques that have been outlined, and each one provides an explanation and a solution that has been tested. Latest techniques that can be beneficial for getting the best hair transplant results in Dubai.

In fact, there are non-surgical methods that might slow the growth of androgenic alopecia and even encourage the growth of new hairs (i.e., minoxidil, finasteride, dutasteride, low-level laser light therapy, platelet-rich plasma PRP and some home effective remedies). Besides that, patients suffering from androgenic alopecia can now restore a more young and natural-looking aspect to their hair through hair transplantation, due to recent developments in surgical hair restoration techniques. Medical treatment for hair loss is outside the scope of this article. The surgical techniques are the main topic of this article.

Scalp Hair Growth Anatomy

To get the best hair transplantation in Dubai is to maximize its effect thus, it is important to understand the basic anatomy and life cycle of scalp hair. 

A hair follicle is made up of a hair shaft, two sheaths (the inner and outer) around it, and a germinal bulb. The follicle is divided into three sections: the inferior segment, the isthmus, and the infundibulum, which run from the skin’s surface to the attachment of the arrector pili muscle (from the muscle insertion to the base of the matrix) [2]. The growth cycle of scalp hair is as follows:

• The hair follicle’s active 2- to 6-year growth period is known as anagen. At any given moment, 90 to 95% of scalp hairs are in the anagen phase.
• The hair follicle’s 2- to 3-week involutional phase known as catagen is marked by acute follicular regression. At any given time, less than 1% of scalp hairs are in catagen.
• The hair follicle’s 2- to 3-month resting period known as telogen is marked by a complete cessation of all activity. At any given time, 5 to 10% of scalp hairs are in telogen.
• The daily hair follicle shedding phase known as exogen is characterized by the loss of 25–100 telogen hairs, which are then replaced by brand-new anagen hairs.[3]

Methodologies for Hair Transplantation

Surgeons who had their training in Europe, North America, Pakistan, and India are available in Dubai’s world-class healthcare system. They have certifications in specific fields like hair transplants. For the best hair transplantation operations in Dubai, they offer the same outcomes as in the west. But methodologies and techniques used in different clinics in Dubai are common and advance with every passing year. Here details of these methodologies are discussed, starting from basic steps that are the same in each surgical technique patient opts for a hair transplant.

Planning, preparing, getting under anaesthesia, gathering the grafts, stabilizing them, transplanting the grafts, and dressing make up the process of hair transplantation.  Blood tests, a complete medical condition history, and marking is the patient’s planning. Anaesthesia is performed after any necessary hair trimming and cleaning with antibacterial treatments. Both the donor and recipient areas get anaesthetic injections. This makes it possible for an expansion to simply harvest and transplant donor area follicles.  

Local anaesthesia has been used throughout every surgery. The hair is trimmed to a length of 1-2 mm. The hair follicles are harvested using a micromotor system. The follicles are harvested while the patient is supine. The follicle is separated from the surrounding tissue with the use of the motorized system’s sharp punch (about 3–4 mm in depth = deep dermis layer)[4].

A frequently used hair transplantation procedure is called follicular unit transplantation (FUT). This technique involves shaving the donor area and doing an elliptical excision to collect hair follicles. The ellipse’s dimensions are determined up to the recipient area where the graft is to be placed. To minimise scarring, the donor region is carefully covered. Under magnification, the additional tissues of the hair root and the surrounding epithelium are dissected from the collected hair skin. The grafts are then properly placed in the recipient area.

FUE is a method that uses circular punches to remove follicular units with one or two roots. It was suggested to use 2-4 mm punches instead of 1 mm since the transection rate in 1 mm harvests is unusually high.

A front hairline is created using FUE, and the bald region is transplanted using FUT, which includes strip harvesting (with bevelled incisions) and slicing of the strip under magnification. Micro-refined microfollicular hair transplantation is a recently published technique.[5]

DHI, a modified form of FUE, is comparable to FUE in terms of the hair follicles that are harvested, but the implantation of the follicles is done using special devices that are made just for this reason. While oblique-cut needles in the range of 0.40 to 2 mm are available on the market, the size of the pen’s needle may vary. As compared to FUE, this procedure enables the surgeon the ability to graft the recipient area denser while causing less damage and a bloodless field.

Whatever the technique used in the surgical procedure, clinical care staff with experience in the post-operative treatment of Hair Transplant should closely follow up with the patient during the first post-operative phase to monitor for any potential problems, such as infection and the development of ingrown hairs. The patient should be informed that it may take many months for the implanted hairs to regrow after they are lost, which often happens after a few days.

Takeaway

Better outcomes will be obtained from further research. It’s feasible that the entire operation will be carried out entirely by robotic and automated devices as technology advances in medicine. Combining surgical procedures with other choices may provide patients with the highest chance of regaining sufficient density and natural-looking hair. As far Dubai is known for increased medical tourism there is a high chance that more advanced AI-based techniques will be used for the best hair transplant in Dubai.
