I Just Purchased an Inexpensive Hand Video Microscope and I Think That My Hairs Are Miniaturizing?

Yes, you are miniaturizing with thinning and wispy hairs that exceed 20% of the hairs that you are looking at. This is the early part of the balding process which often progresses with eventual loss of these miniaturized hairs. I put a few arrows to give you different stages of miniaturization in your hair, from thread-like to half a hair shaft volume. See arrows below.
