Is My Density Above Average?

I’ve read that the average density of hair in the donor area is 2.0 hairs per square millimeter. I have a density of 2.2, which obviously is above average but how much? Is it slightly, moderate, or very high? Also, what’s the highest density you’ve ever seen on a patient?

The difference between a 2 or 2.2 density could be the normal variation around your scalp. High densities have ranged from 2.6-4.0. Let’s take a look at a patient with a density of 4.0, who has now had nearly 9200 grafts transplanted. Before on the left, after on the right (obviously). Click the photos to enlarge.
