Hi! I have a Syrian hamster who is roughly 1 year and 11 months old. He has been balding for the last six months, and I have recently noticed the top of his head has been getting dry and scabby (please see the attached photo). I would appreciate any advice for what I can do to treat his skin. Kind regards, Michael

Hair loss and skin infection in hamsters is most commonly caused by either ringworm, a bacterial infection or skin mites. This could also be caused by trauma to the head, especially if there is another hamster in the enclosure. It is also important to note that the life span of a hamster is about 2 years so Flash is considered ‘geriatric’. It would be a good idea if you had him checked out by your veterinarian to ensure nothing else too serious is going on. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
