It seems you already have your answer but I thought I would share anyway. I had lost most of my hair up front and was starting to loose some in the back. It wasn't smooth bald, I still had the baby hairs. I'm on spiro and e and after nine plus months it is all coming back. I am almost to the point where I won't need a headband either. It will probably be a couple years until I know for sure how much will come back, but I am happy now! Winter is here but I rarely wear hats, never owned a wig.
From your pics I would say you're in no danger.
