It's great to see other curlies choosing to gray naturally! I've been going gray since I was 18. It's been a slow process and for a few years in my early 30s I colored my hair. But, I got tired of how crummy my hair felt and the not so flattering orange hue that would come along after a few weeks so I chopped it off as short as I could stand and have been natural ever since. I'm about 65% gray and it's coming in all over so it blends in nicely with my light brown hair. I get lots of compliments on my haircolor (and curls too).
I've read that both long and curly + gray is not attractive, but I don't agree.
