I was born a brunette and had a quarter sized blond patch of hair on my left side behind my ear. Growing up I always got asked why I bleached my hair I'm 29 now and think its so cool.
I don't know, but my daughter was born with a blonde streak on the right side as well as blonde lashes on the right eye! She is 10 yr old now and still has it! She had a blocked tear duct in the right eye as a baby and her front right tooth was really slow to grow in...weird.
