Not OP, but I've had this happen to me during a very stressful period of my life. In my case, small patches of skin went really dry and itchy, and eventually fell off, like dead skin after a sunburn. My dad had it on his scalp once too. He had a few circular patches (~3cm) with total hair loss, which eventually grew back. Neither of us had that happen again.
