Ive been shaving since 83 and still pretty much woulf have a full head og hair if I let it grow. you can still see some shadow on me though its not as pronounced as it wasyears ago. I sort of like the shadow-its lets people know I comb my hair with aSchick razor everyday
I agree with timmj, it's almost like a badge of honor..
Shadow used to really bug me, but now at the grand old age of 5 months today

, I've learned to live w/ it, I can't do much about it but keep it smooth, and since I can't do a day w/o shaving--at least so far--I'm generally pretty clean and clear except for the hour or two in the morning at the gym, and then it's just aggravating "velcro" stubble. So I'm careful taking my shirt off, then shower & shave and clean and smooth--one of the best feelings I've had, and I have it every day!!!!!!
