The effect is not only closely related to the condition of alopecia patients, but also directly related to the choice of technology and the professional quality of hair transplant doctors. Many patients choose the hair transplant hospital because of the lack of knowledge about hair transplant, which leads to the failure of hair transplant.

In fact, the technical principles of fue and fut are similar, but there are great differences in technology. Fut is cheaper, because it is an operation, it is necessary to cut the scalp of hair follicle tissue from the pillow, then extract hair follicles from the scalp, and then suture the scalp, which will leave obvious scars on the pillow. Then fue technology does not need to cut the scalp to extract hair follicles, but directly uses special tools to extract hair follicles, so it will not cause obvious scars and the effect is natural.
