I even did that method of using a roll of toilet paper to take the picture of the scalp with more light, and even so, the top of my head doesn't seem to have thinner strands than the one on the side of it, but in the crown area it is as if I had less hair growing.
And there is also a problem, my hair was never thin, to tell you the truth it is very thick, I am not having a significant hair loss, but from time to time I see almost invisible hairs loose on my keyboard computer, extremely thin and colorless hair, it worries me a lot. I am considering going to a dermatologist, if I do I will tell you what the result was. Thank you all.
The first photo is from the top of the head, the second is from the side.
