To find out how many grafts you need for the crown, there are a few things you need to know first:
(1) Thickness of the hair – fine, medium, or coarse (the thicker the hair, the less the number of grafts you will need)
(2) Character of the hair (wavy is better than straight)
(3) Color contrast between your hair and skin (brown hair on light skin often means more grafts, while gray hair requires less hair)
(4) The crown is the place where the direction of the hair changes.
If you want the swirl, you need to discuss this with your doctor. Your balding area is similar to mine, and I had 2,700 grafts placed into it over the past 25 years. So, if I were to estimate a range of grafts for you, it would be between 2,000-3,000 grafts, modified by the above.
