I have not used the N/A designation for my hair color. I havve used brown in the past but now the facial hair is getting grey. By the way, my new avitar is me, but the goatee is brown because of Just For Men. But I have quite using it now and have a greying full beard. Also when it comes to clean shaven folk, unless they shave their brows, the brow color would probably be considered the hair color. Of course there is also chest hair and "other" hair.....but we won't go there!
