You look great! love the short hair.
I'm 46 and grey. I did get some "highlights" a few months ago - i wanted purple, I wanted it to look like I did it on purpose and not a mistake at trying for a real color - the best my hairdresser would do was orange. It still looks like attempts at highlights of a real hair color. Won't do it again, but I don't dislike it.
I love your color of gray, it's beautiful.
