At present, hair transplantation is mainly divided into two categories, one is FUT, the other is FUE, and the other is hair follicle unit extraction. Therefore, the first method of FUT, that is, the strip extraction method of hair follicles, is to cut off a hair follicle, then divide it into independent hair follicle units under the microscope, and then stick it on the hair follicle in the middle of hair transplantation, so it can get as many hair follicles as possible after extracting the scalp strip with the smallest unit area, but its disadvantage is that it will leave strip scars. Of course, if you can keep more than one centimeter of hair, you can completely cover this scar.
The second method, called FUE, is to extract hair follicle units, which is one of the most popular methods at present. Its advantage is that it is punctate, and the whole hair follicle can be extracted at one time, so it is separated and scattered, and the scars left are punctate, so it is not easy to see when your hair is short, but its disadvantage is that the area you need to extract will be large, so you may need to cut your hair.
