My dad has black hair and though my mom has dyed her hair blonde for years, she is still a natural redhead. As a result, my hair is usually light brown with highlights of blonde, red, and auburn... and over the years has went from a dark blonde to even being red for a couple of years. Though I was born with black hair.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
