Leo's skin could look like that for any of the reasons you listed and add skin mites to the list as well. The problem with skin conditions is that they all clinically look the same. Diagnostics or sometimes a response to treatment is the only way to know what is the underlying condition. For a young cat like Leo, fleas, skin mites or ringworm is more common but allergic reactions are not impossible. That lesion on his head looks pretty inflamed. if you don't see any obvious cause like fleas, I recommend to have him examined by his veterinarian. The veterinarian who will look for other clues on the physical exam to get a better idea what the underlying cause is. Ringworm and mites can be ruled out with some simple diagnostics and he can receive medication to heal the lesions. You may start an omega 3 fatty acid for cats as this can help with inflammation and skin health but it may not fix the problem. Best of luck and please feel free to post any additional questions.
