Hair shedding is caused by temp and length of day.  In fact, much to do with animals, including estrous, is guided by optical light stimulation. 

I would say your house may be a bit dry with the heating season well underway.  Between the shedding, grooming and dry skin, the cat may be just dealing with sinus allergies.  My suggestion is a good baby oil bath.

At the very least, it might make for some fun youtube video posts.
