My four-year-old niece, Mary, has gorgeous red, curly hair. She notices and comments whenever she sees someone else with red hair. Other people's red hair is never as pretty as her red, curly hair though.
Mary informed me that I have rainbow hair like Christopher, her seven-year-old brother/my nephew. I think she was referring to his natural highlights. I am sporting a good six inches of natural hair color for the first time since eighth grade. My rainbow hair is natural, thank-you-very-much.
