I love salt and pepper and also straight up silver fox white!
I don't love hair color on men.
Perhaps if I had ever seen a job done that looked good, I may think twice...but somehow it just doesn't look right, like ever.
I believe the reason is that since a man's hair is typically very short, and since the roots of our hair grows out very quickly, so say your hair is just over two inches long at the longest part, about 1/3 of this total length will be gray or white again within 2 weeks of coloring your hair. So now you've got hair that is perpetually half white and half colored. It only looks totally colored for less than a week after doing it.
This is the same problem for women, but since our hair is typically longer, we can get away with some root growth for a little bit longer as it tends to get hidden under longer hair. But within 3 weeks (I'm guessing is typical) a woman who has mostly white hair and is coloring it a dark or darkish color will have nearly an inch of new root growth, all of which is white again. And those roots glow through your longer hair eventually and you can't hide them, thus having to get a root job or full color every 3 weeks or so.
This period of time when you have white roots is much harsher on a man's hair, it just looks terrible. It doesn't look great on women's hair either, but better for a short while.
I actually have a whole bride of Frankenstein level of white streaks going on in my hair, along with a lot of steely gray. I actually like my hair in its natural gray state, but all of my friends and kids have convinced me that it just ages me so drastically that they want me to color my hair. Ok, fine, they won.
I was coloring it dark, back to my natural brunette at first...but I gave up trying to fight those stupid constant growing white roots. It was just unmanageable and too damn much work. For me it was at least weekly root jobs and frequent full color jobs. I have long hair...and you either do it yourself, which is a hassle, a huge mess, and can take 90 minutes or more, or you go to a shop and pay quite heavily for this every week and then also at least once a month. It ends up consuming your life.
So I started messing around with the color myself, and with bleach. I'm pretty good at this from experimentation in my teens with my hair and anyone else's hair who would let me try stuff on them. Eventually I ended up with pink bangs and my bride of Frankenstein side streaks are pink, too. The rest of my hair is my natural brunette color, though it is from a bottle still. My roots still grow out fast as usual, but being white next to the pink hair color, they don't tend to glow as much and are somewhat hidden. I don't have to do a root job very often.
This suits me and I love my pink hair. It does still require a heck of a lot of work, but I can do it all myself, and now I go in to a shop only when I feel like being lazy and not doing it myself. I've learned hacks for clean up and other processes when doing a non-natural hair color and now I've got a good routine down. People constantly ask me where I've had it done because it is really cool and looks like a professional job. Where I live, there are lots of people with wild colored hair so it isn't that unusual, but mine is still a rockin' fabulous job in a sea of wild colored hair.
I could appreciate a non-natural color job on a white haired guy if it was done right. But that's quite a leap and not everyone could pull it off, or ever want to.
