Beef, I am just wondering if your scalp could be getting really dry. I see your in MD and I am just curious if you have a dry heat running in the house alot. Not sure if your using a moisturizer after the shave but you may want to just test and apply some like every 4 hours or so just to see if it helps. Also a humidifier might help but that could be extreme.
Just tossing some ideas....
