The cost of hair transplantation depends on the number of hair follicles transplanted and the technology adopted. Generally, it takes 1000- 1500 units to transplant hairline. Hair transplantation techniques are mainly divided into two types: marked hair transplantation and unmarked hair transplantation. Generally, the cost of unmarked hair transplantation is twice as much as that of marked hair transplantation, and each unit is about 10 yuan. However, there is no need for surgery in the process of hair removal, and the risk is small.
