How do you determine your Donor Density?

If you take a photo of your cut hairs like this with either a hand video microscope (available on Amazon) or a good camera with a zoom in feature, you will see the follicular groups. The average Caucasian density averages 2.1 hairs per Follicular Group so if you count the number of groups and the number of hairs, you can know for certainty what your donor density is. In these pictures, the circles in C and D have higher than normal donor densities as the average number of hair in each Follicular Unit averages significantly above 2.1 hairs per Follicular Unit. That means that the person who has the higher donor density has more hair to transplant and if they want to do FUE, can do certainly more grafts based upon the chart here: https://newhair.com/resources/#tab-id-4
