Hi V!
Oh what a cute munchkin! I have one that has allergies (enviro seasonal) & yeast, so she has a lot of itchies. She's also very allergic to flea saliva, she breaks out in red angry hives! Her hair is very fine & breaks easily. When she's suffering from allergies, she'll leave clumps of hair on my bed.
All I can do (besides meds which we stopped bc it's basically steroids) is give her a bath 2 x's a week when pollen count is high in a natural coconut based shampoo, I use espree. Coconut is so wonderful, anti-inflammatory, anti-fungal, anti-bacterial, it's amazing stuff! I apply the oil on her rash & it's gone the next day.
It can simply be genetics too.
