I shave most of my face, and my beard grows at a decent rate. But for some reason, there is very little of it in the morning. A couple hours later, I'm full of stubble. I would probably look better if I shaved before going to bed! My best guess is that it retracts into the skin, or the skin expands to cover it, during night(*). Then the skin contracts again when I get into fresh air, or something. A strange thing it is, anyway.
