Hair Care

My youngest daughter has developed the routine of coming up behind me when I am sitting in a chair and combing my hair. At first I thought she was just pampering me, but now I see she has a motive. She combs through my thick, dark locks in search of... it pains me to say - gray hairs. Our routine goes something like this:

Comb, comb, comb.
HER - "Oh, this one is definitely gray!" YANK!
ME - "Ouch!!!"
HER - "See dad, it's white as can be! Wait, I think I see another one..."

I'm not worried about getting gray. I'm concerned with losing too much blood from my scalp as the gray hairs get easier to find.
