I am 8 months into going grey, however, I chose to not cut my hair. For the first six months, my stylist wove my natural color in as "highlights" so I wouldn't have a skunk stripe. This last trip I had her hold off and will see how it goes. I may have her do a few in 8 weeks as my bangs are looking a little strange but the rest of my hair looks pretty good so far.
I am with you, if I decide grey isn't for me, I will just dye it again. I think yours looks great! My pet peeve is women well into their 70's who are still coloring and highlighting, personally I think that makes them look older.
