If she is not on flea prevetnion this might be a reaction to flea or mosquito bites. Even if you see nothing on her hairless body, and even if she is indoors only, there could still be biting insects possibly fleas or mosquitoes in your environment.
Another possibility is skin mites though those usually itch, or ringworm fungal infection.
This could also be from contact with wool or a cedar bed or from sensitivity to a perfume in a cat litter.

Some owners of this breed recommend weekly bathing with a shampoo special for cats to prevent skin issues.
I'd suggest having your vet check this out to see if an underlying condition is found and if not ask about bathing the cat in either a medicated shampoo or a mild cat shampoo.
Hope this helps you!
Skin issues show up pretty frequently in cats overall and I think it may just be more obvious faster in pretty kittens with barely any fur!
There is one more general cat skin issue you might want to read about called miliary disease

and its pretty much a combination of what I've told you but does mention nutrition as a possible issue.
Could be you'd see some improvement using a multivitamin mineral supplement such as Felovite or another one.
But a bath might be a good place to start. I'd suggest a shampoo made special for cats and not using one with any flea products in it.
Could be this is just clogged pores.
