It sounds like your hamster has mange. Get him to a vet ASAP
no your hamster can get sick
your hamster might be dying or it is sick
If the hampster is in fact sick, then yes
Fleas! Or an ear infection, if it's in the inner ear.
Check your hamsters food. It doesn't matter where you get the food, how you get the food your food could have weevils. The weevils go inside the cage when you put food in there and cause irritation. Put your hamster food in the freezer to prevent this. OR, It probably has mites. My hamster had mites, and she was losing fur on her back. We were wondering if we should take it to a vet, but she ended up healing by herself and is now perfectly fine. I'm not saying this is what you should do, because your hamster might not heal by itself; she might get worse. If she loses more hair, and still doesn't seem to be getting any better, I'd suggest bringing it to a vet. I hope your hamster gets better soon!
When a hamster gets stressed, many factors have already attributed to this since it has already happened. A lot of the time, a hamster will get sick when stressed. If you have a mother hamster who is stressed, then she might eat her babies.
No.

No you can't feed straw to a hamster or else it will get sick!
If your hamster has hair loss this could be a symptom of a disease or parasites.
