How is hair transplantation performed in hair transplant surgery?

Hair transplantation surgery is a process that involves a series of meticulous steps to transfer healthy hair follicles to areas affected by hair loss or thinning. This typically includes determining implantation sites and follicle extraction, follicle separation and preparation, preparation of recipient areas, follicle implantation, post-operative recovery, and care. A detailed explanation follows:

1. Determining implantation sites and extracting follicles: Initially, the physician designs a suitable hairline and implantation area based on the patient's facial features, age, gender, and degree of hair loss. Subsequently, healthy hair follicles are selected and extracted from the donor area. Generally, follicular unit extraction (FUE) or follicular unit transplantation (FUT) can be chosen. FUE involves extracting follicles individually, while FUT involves removing a strip of skin containing multiple follicles, which is then dissected into individual units.

2. Follicle separation and preparation: Extracted follicles must be carefully separated under a microscope to ensure the integrity of each follicular unit. Manual separation is usually recommended to shorten processing time and maximize follicle viability.

3. Preparing the recipient area: In areas affected by hair loss or thinning, the physician administers local anesthesia and performs disinfection to minimize discomfort and the risk of infection. Tiny incisions or slits are then created in the area to serve as recipient sites for the follicular units.

4. Follicle implantation: The separated follicular units are implanted one by one into the prepared incisions or slits according to the natural direction and angle of hair growth. This process requires precise handling to ensure the implanted hair appears natural.

5. Post-operative recovery and care: After implantation, the follicles gradually adapt to their new location and begin growing new hair. Patients should follow the physician's post-operative instructions, such as avoiding touching the transplanted area and regularly cleaning the scalp, to promote follicle survival and hair growth.

The entire process requires professional expertise and equipment support. Therefore, it is recommended that patients choose reputable and accredited medical institutions for hair transplantation surgery.
