How many hairs per square cm? I've been diagnosed with CTE and have been shedding for 2 years.

It depends on your background, but it does sound a little below the average, but still within the realm of normal hair densities, especially if you just naturally don't have very dense hair.

It really depends on your ethnic background. For a Cacausian, a number closer to 200 would be more in the realm of average density. I generally give the range 165-220. Individuals with afro textured hair have lower density.

I measure hair density by counting the hairs in each follicular unit. For CTE, some of the hair will be miniaturized so that is what you need to have measured.
