Kitty, I can't help with the loss, but as a temporary solution until it grows back, at least for around the temples, you may want to get some of this:

I actually use it because my hair is extremely thin around my temples from using chemicals and it's embarrassing to me, but this hides it.

it sucks though. I'm sorry and I hope it does grow back.
