What do those numbers mentioned in connection to hair transplantation represent?

The amount to be transplanted in hair transplantation represents the number of hair follicles. Regarding the hair shafts, the number of hair shafts may exceed twice the number of hair follicles. In this sense, offering the patient a number for hair shafts before the hair transplantation can be confusing. Considering that each hair follicle (follicular unit) contains more than one hair shaft, transplantation of 3000 hair follicles means that 8000 to 10,000 hair shafts are being transplanted.
