49 and only one grey strand? That's awesome. I'm 45 and I'd say my hair is about 10% grey, the rest medium brown.

I used to "search and destroy" any grey hairs that I spotted. Now I've kind of given up on yanking them out -- there's just too many of 'em.

When the greys first started showing up, I tried some of the home coloring products (Clairol, L'Oreal, etc.). Boxed hair coloring is fine the first time you use it, but then you have to deal with the roots that show up in a few weeks. Ugh, I hate when you can see the roots. In my experience, it's nearly impossible to color just the roots on subsequent applications, even with the kits that are designed specifically for that purpose. Also, no matter what color I tried, eventually the color turned kind of brassy on my hair. I didn't like that it looked so obviously fake.

I'm not willing to spend hundreds of dollars to get coloring done at a professional hair salon, so I don't know how much better that might work.

In the end, I decided against continuing with coloring my hair. It looked fake, and it was just too much trouble. Don't get me wrong -- I'm not happy with the fact that my hair is growing grey -- but I'd rather keep it natural.
