Q: If I had a hair transplant using Follicular Unit Transplantation, how many grafts would be in a 15cm by 1cm donor strip, on average?
A: In a person with average donor density there are approximately 100 follicular units per square centimeter. A 15 cm long strip would have slightly less than 1500 grafts due to the tapering of the strip ends.
Therefore, in a hair transplant of 1500 follicular unit grafts, one should take out a 17 cm x 1cm strip (that includes the tapered ends). This is 15cm2.
