I was just reading about this the other day and I came across an article that recommended using shine sprays on the dome. These products are typically used to make hair shiny but will work just as well on the scalp. A little over a week ago I was at the barbershop getting my facial hair trimmed and I noticed that one of the barbers was getting his head shaved by another barber in the shop. When the shaving was done, they sprayed a cocoa butter shine spray on the barber's scalp. Let me tell you, it gave him a mega-watt shine. I've been doing the same myself and have been getting an excellent shine as well.
