For static, you can spray Static guard on your hair brush and brush it through your hair. It works GREAT. I just try not to spray the aerosol around the cats. It doesn't leave any residue, doesn't stink and doesn't weigh down my hair.

For itchy skin, try Scalpicin (sp?). It's a clear liquid that you squeeze right onto the itchy part of your head. It has menthol in it and really cools. It also doesn't leave anything in your hair.

As for the flakes, I can't help you there Maybe try a moisturizing shampoo?
