Hair transplantation refers to the surgical redistribution of a portion of hair from the dominant donor area (occipital region) of the autologous scalp to the area of hair loss. Hair transplantation does not increase the total amount of hair, but redistributes it for cosmetic purposes. FUT (follicle unit transplant), a diamond-shaped flap is extracted from the back of the head, the hair follicles are separated out and transplanted to the hairless area. Advantages: It is suitable for people with large or serious hair loss, and can take up to 3000 units at a time, and the post-operative effect is ideal. The price is the lowest among the three, and the result is ideal. Disadvantages: After the surgery, a scar will be left on the donor area. However, it will fade away after a few months. FUE (follicle unit extration) has a small area of trauma due to the individual extraction of hair follicles and the individual implantation of hair follicles, so after the surgery, no scar can be seen after the blood scabs fade. 6-9 months later, the hair can grow to its original length.
