When you are finished brushing or combing your hair you should
immediately remove it from the brush or comb and either burn or
flush it down the toilet. This prevents any one who wants to do
harm to you by taking your hair to a Voodoo person and having that
person cast a spell on you or have you fixed with a spell so that
you will come down with some untraceable illness.
