The hows and whys of hair

The hows and whys of hair

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? Plus: A brand new Moment of Um answers the question: "Why does my dad get fuzz in his belly button?"
