I think you will find this article interesting:

They take a 2D bitmap, apply canny edge detector and then regroup segments of the different edges based on how likely they belong to a same object - in this case hair (and give criterias for such regrouping).

I think you could use this to know how many objects there are on the image, and if the image contains only hair, then you'd have a count for hair.
