You can have stylists highlight portions your hair-without dying all of your 'remaining' hair.

I'm 51, and the salt is starting to become more and more apparent.
I went to the drug store and stood in the men's hair color aisle for a good half hour reading the ingredients, directions, warnings, etc.
I walked out with a Snickers bar.
I will never do the over-the-counter, do-it-yourself thing. Too much mess, too much upkeep. If I decide to get my hair colored, I will go to a pro and pay to get it done right.
But for now, salt and pepper suits me just fine.
