Hi there, I'm sorry your little hamster is having trouble. Hair loss can be from a number of things- skin parasites like skin mites are very common in these guys. Also, there can be hair loss from endocrine diseases , overgrooming from stress or other things. Your vet can test your friend for parasites and then prescribe a safe medicine that you can use. Over the counter meds, such as dog and cat flea products, would be too strong and could hurt your pet. if it is not parasites, they can check to see what else might be going on.
