tonight i noticed for the first time while i was looking at myself in a mirror under a bright light, that although i couldnt see my shadow cuz of the light i saw almost a 3-D like outline of my hairline. i was wondering if thats normal. i cant really explain it. it was like an above the skin outline of where my hair was without a shadow. you can easily feel it after i shave my head smooth too. it leaves a bump.
