What is a good hair dye for man who covers gray?

I know there is Just For Men brand and Clarol has natural instinct. Anyone ever used either brand or know of someone that does? Also is it better to go one or two shades lighter than your hair was when coloring it? I was told it looks better not to go so dark.What is a good hair dye for man who covers gray?
The best haircolor to just cover gray is a semi perment color, go for you shade, because gray hair is resistant to color and will show up lighter. you can use any boxof color loreal's color is the best in my opinion. the pircture on the box doesn't matter, hair color isn't really gender specific.What is a good hair dye for man who covers gray?
I would suggest to go 1 shade to start. you can always do more. Just for Men is the safest over the counter too... thanks Jen - http://beauty-tips-free.com
