No matter whether it is male or female, the hair at the donor site must be cut off. That is to say, in the place where the hair follicle is extracted, it is necessary to cut that part of the hair short, generally leaving about 0.5cm of hair. Too long hair cannot be extracted, and too short hair is not convenient to plant.
The principle of hair transplantation: the hair follicle on the back of human body is taken as the hair source, which is separated into single or multiple hair follicle units, and the hair follicle units are transplanted to the parts that need transplantation through fine microsurgical techniques, such as head, eyebrows, eyelashes, beard, chest, eyelashes, genitals and so on.
Let it naturally survive and grow in new parts, so as to achieve the purpose of repairing the local hair distribution density and achieve beautiful results. In fact, hair transplantation is also a kind of "robbing Peter to pay Paul", which achieves the effect of concealing defects and visually makes hair more lush.
