Wonderful article with everything you could ever want to know about grey hair: Grey Matters.
Of course (don’t tell anyone) if I had that wonderful thick silver hair I wouldn’t color mine…as it stands mine is more like the pan in my outdoor grill threw up on my head…so my hair looks more like the photo below. Plus my daughter said I can’t stop coloring my hair until she graduates from high school (so nobody will mistake me for her grandmother).
