At present, the measurement or evaluation unit of hair transplant surgery in the world is hair follicle unit (FU). Different hair loss grades also determine different hair loss areas. The higher the grade, the more hair follicle units need to be transplanted. Because the operation of hair transplantation is based on hair follicle units, the charge is also determined according to the specific number of hair follicle units. There is a general formula for the calculation of hair transplant price: hair transplant price = hair follicle transplantation unit × hair follicle unit price.

According to different hair loss areas, hair transplant techniques are different, and the price ranges from thousands to tens of thousands.
