I do know of another method which has been used by my Italian side of the family for years - they make an egg wash, just a beaten egg - and brush it over the loaf before putting the bread in the oven. Not sure where that idea started, but I use it when I bake egg bread every Christmas in the family tradition. That may be considered cheating by the bread baking purists, but it sure does make a nice looking loaf of bread. When I find a picture of one I'll post it.
The photo above is a loaf of egg bread I made last Thanksgiving without the egg wash and it is not shiny - but it sure tasted great anyway!
