It's a shame that for women, grey hair is (largely) seen as ageing, but for men, it is distinguished. Just look at Mark Harmon (yes please!), Richard Gere, George Clooney. So, my advice is, try and just let it grow down if you can bear to. When my grey first came thru, it looked like I had a very short paintbrush stuck to my parting, sticking straight up (awful), but after plucking for several months and just intensifying it, I braved it and now have two quite nice silvery streaks, and a thin greyish fringe, which does look a bit strange as the rest of my hair is a light brown! people do nitice it, but I've quite grown to like it. if you really can't bear it a good hairdresser will advise, as most commerical products don't cover grey for long. good luck in whatever you do!! :)
