Peach fuzz. Chin hairs. Mammalian ponytails. WHY DO THEY HAPPEN. Yale researcher and associate professor Dr. Valerie Horsley stops by California to chat with Alie about the nature of hair and why it grows in the wrong places, the causes and remedies for hair loss, the grossest museum ever, and why we love and hate and need our hair as animals. Also: Dr. Horsely's decision to run for office and Alie's disgusting confessions, per usual.
