Hair micro-grafting or follicular micro-transplant
Hair micro-grafting, also known as follicular micro-transplant, is comprised of transplanting hair from areas that are densely populated with hair, such as the nape or both sides of the head, to areas with scarce hair or lack of hair, affected by alopecia.
The technique consists of micro-surgery, during which follicles of hair are taken from a strip of skin, achieved with a small incision in the scalp. This strip is divided under visual magnification to get the Follicular Units of 1, 2 or 3 hairs.
The micro-grafts of various follicular units are "big" micro-grafts of many hairs, where each one can develop a certain direction. Therefore, the effect could be unnatural in appearance.
To get better results, people have been working with the transplant technique for a single Follicular Unit, marked by the grafting of one follicular Unit maximum.
Micro-grafts are apparently a definitive alternative for a certain type of baldness, where the individual has a sufficient quantity of donor hair.
