You are not alone, Steve my friend. I do exactly the same. Just for men job - Dark Brown. I didn't used to mind the greying look but MissH convinced me that it does make me look a little washed out. Now I've started dying it I think it looks much better.
I've had a few baldie work colleagues sneer at this practise. I simply respond by brushing a hand through my thick, dark hair. They however, are left to contemplate which point they need to stop when washing their face.
