Sorry...I'm not a woman but I was just asking this to my wife the other day. I'm 40 and the only gray hair I have is either in my nose, on my chest or on my nutsack. The latter area being because probably not enough sex and that area is getting stale....LOL! I know..too much information there....but anyway...my hair is as black as it can be with no signs of it turning gray for awhile. That's with two kids too! My wife loves gray hair on men and she does think it is sexy. Maybe I should dye mine.
