Interesting topic, hair loss. Did you know it can happen with many different illnesses or conditions? Not only did I lose hair when very ill with MAC, and later even a little more from the antibiotics, but I also lost my hair years ago when I had heavy metal poisoning. And during/after pregnancy. And after 3 major surgeries in one year. And when I had Graves Disease (hyperthyroidism.)
Each of these also caused me to have weak or easily broken fingernails and toenails. And dry, delicate skin.
It seems that the body will automatically shut down nourishment to less-essential systems to send it to more critical places.
