Estimating lifetime donor supply

I’ve attached a magnified picture of my donor area that I captured; a couple of your posts I saw stated that folks can send you pictures of their donor and you can use your personalized formula to estimate their donor. The caliber of my hair follicles are 55 which I’ve been told is in the middle. Would you mind helping me estimate my donor grafts availability?

There are 29 follicular units I counted (click on the photo below), and I took the total hair count and divided it by the number of follicular units 72/29= 2.5 (rounded). This means that you have a donor density of 2.5 hairs/FU, which is 24% higher than the average Caucasian Donor density.  With a hair thickness of 55 microns as measured by your micrometer, I would suspect that you can easily harvest between 8000-9000 grafts in your lifetime.  Of course, the type of FUE that picks out all of the high numbers of Follicular Unit hair grafts would reduce this number substantially.  That means with proper FUE performed, leaving enough good grafts behind, you can bald to a Class 7 pattern and still get hair.
