My hamster lost all his fur, please help

[qwq]

First time posting here. I don’t really know what to do. I own a long haired Syrian hamster, and he’s almost two years old. Recently, he just suddenly lost all his hair . At first I noticed his hair was looking a little light, but I thought it was just him getting old. Then a few days later, he lookin like a mole rat. No offense to him he’s still really cute tho. I don’t know how this happened, or how to help him??? We got oasis vita drops for his water, as well as some organic oil that’s supposed to help with mites and dry skin, his skin is really dry too. He has dandruff(I think), and his skin just looks painful and I’m scared that I’m hurting him when I hold him. I don’t know how this happened over night. If anyone can help clarify or give advice it would be greatly appreciated. First time seeing something like this out of the 8 hamsters I’ve had.

Have you checked out Cushings disease in hamsters as this does sound like Cushings. There are a few threads on the forum about this with advice but it would be best to consult a vet to see what they think.
