Any insight into this - please??? included pics

Hello,

I was recently diagnosed with AGA via a scalp biopsy. I have rapid diffuse thinning which I especially noticed through the month of September. However, my dermatologist can't rule out something else going on because I am also losing a million of these tiny hair fibers. Does this happen to anyone else? Is this part of aga? They are everywhere - bathroom, car, windowsills, etc. :( Thank you.
