At present, there is no specific requirement for the cost of hair transplant in China. Generally, regular hair transplant hospitals charge according to hair follicle units. Generally, the cost of seamless hair transplantation is 20 yuan 10- a hair follicle unit, and the cost of hair transplantation ranges from several thousand yuan to tens of thousands of yuan. The main factors affecting the cost of hair transplantation are the patient's own hair loss and the selected hair transplantation technology. Hair loss is divided into seven different grades. The first-degree alopecia is not obvious without hair transplantation, and the second-degree alopecia means that the hairline moves back about 1cm and needs to transplant about 1000 ~ 1500 hair follicle units. Third-grade alopecia means that the hairline moves back about 2 ~ 3cm, and about 1500 ~ 2000 hair follicle units need to be transplanted, and so on.
