So Long, Fathead

There is a small window in the restroom at work.  At a certain time yesterday afternoon, I noticed my shadow.  Specifically, I saw that I could see through the shadow of my hair, since it is so thin on top.  (Again, this is the time to mention Doodles Weaver's line, "Well, who wants fat hair?")  Since my shadow is now smaller, does that mean my head doesn't look as big as it used to?  Or does my head look even bigger, without all that hair to conceal it?
