Mine too. My mom is 58 and still is only maybe 10% gray and that's only right at the temples. Father was younger than that, but still I know he was 50 before I remember noticing any on him.
I don't have any at all yet. And I pray this doesn't jinx me.
I gots all my hair and its all the same color it was 20 years ago... I find like one gray hair every couple of months but that is about it... HGH and test+forever young!!!
