Here at Hair Fairies NY, we had a doctor from India, who was taught while getting her doctoral that only people who didn't wash their hair had head lice, and when she traveled helping under privileged children, wealthy people believed that these children had lice because they were dirty. When she came to NY she was surprised at all the people here, and asked but why do these people have lice if only dirty people get lice. We told her that this is a myth and that head lice actually liked clean hair. She was absolutely shocked to hear this, but happy to know the truth.
