I don't. I kinda like my Reed Richards thing. My upcoming gray keeps me from growing a beard anymore though. My wife just uses a lot of "Sun in" to keep her hair a bit blonder than natural.
My kids still have pretty blond hair, although the older two are turning sandier every year. Along with their relatively olive skintone (a heritage they get from my Portuguese great-grandfather) and their time in the sun all summer long, they look like surfer kids this time of year.
