If you are listening to me speak these words and can understand what I’m saying, then you are a human being. If you are a human being, you are also a mammal, and if you are a mammal, you have hair….or at least the biological capability to produce hair. But why exactly do we have hair?

Learn more about hair, what it does and how it works on this episode of Everything Everywhere Daily.
