My brother and I both started showing greys in our 20's. My dad showed greys in his 70's and my mother hardly had any. I'm about 70% gray, especially in front. i became severely allergic to any type of hair dye. The growing in was kind of "skunky" looking, but now, all I get are compliments and wouldn't change a thing if I could. If a guy can be a "silver fox" than I can be a "silver vixen"!
