What is hair made of?

Did you know your hair is so incredibly strong that it could hold the weight of two fully-grown African elephants?! That is over twelve tons of elephant! In this mind-blowing episode of Science's Not Boring, Mira and Finn dive deep into the wild world of hair to discover what is really growing out of our heads. Get ready to find out how your hair is actually made of keratin—the exact same tough stuff that makes up rhinoceros horns and horse hooves! If you zoom in closely, a strand of hair even looks like tiny overlapping dragon scales! We will travel down into the microscopic underground "factories" inside your skin called follicles to see how hair grows, and answer a massive question: if our hair is so tough, why doesn't it hurt when we cut it? (Hint: you have a whole mop of dead cells on your head!). Discover the secrets of a single hair strand, learn about people with eighteen-foot-long hair, and find out why our heads have built-in sunhats. Grab your hairbrush and get ready for some truly hair-raising science facts!
