I'm back to my natural color for the first time in five years. It's still auburn/brown. I have my dad's hair and if the pattern in the family holds true I'll be getting my greys at 50 and solid white tinged with a little left over ginger by 65.
I have Dad's thick, dark blonde hair and mom's fine hair texture. (So it tangles if you look at it very hard. :\ ) Mom started turning white in her late teens, Dad's only started turning greyish in the last years of his life. So, at 54, I have no idea where this is going. A little skunk streak has started over my right eye- hope it turns out like Mom's, lovely and white. I'm going to leave it alone unless it just turns out dank and awful.
I got a couple shock white hairs just before my wedding. My aunt found one and pulled it out to show me. Too concerned with the wedding, I pulled the other one out myself. Haven't had any since then.
