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 what it has to do with skin and nails, stem cells, how it grows, why some of us have curly hair or straight hair or thin hair or thick hair, and why we love and hate and need our hair as animals.
