First, what a lovely person you are to take him in and heal this little guy. He deserves love and a good home, and clearly he hit the jackpot!

I'm not sure what to say about the hair. So, the rest of his fur is normal? Can you post pics? Often, a fungal issue can cause hair to fall out quite easily - with just a slight pull - your vet can do skin scrape/hair pull and see what grows in petri (for fungal).

I also wonder though, since he's had such poor health before you got him - if his body isn't just going through a sort of "detox" - sometimes as the body detoxifies, strange things can happen. As lots of healing takes place, sometimes it worsens before it gets better.

Hopefully, someone else will have better advice...
