The hair on our heads is on our minds. We have fun with follicles and learn about how they make hair. Our experts help us decipher what makes hair black or brown, blonde or red, and even why it turns gray. From eye lashes to ear and nose hair, this episode has it all. Why do humans have hair and not fur? Why is there hair on the top of our heads? How does hair grow? How does hair become curly or straight? 
Guests: Dr. Shani Francis, dermatologist and the director of the Hair Center of Excellence
Sandy Cook evolutionary biologist of hair at Penn State University
