What’s the difference between your hair, your nails and the top layer of your skin?
Actually, not that much! They’re all made from the same stuff – keratin. They all work in different ways in helping to protect your body.
Hair helps to keep you warm, and stops things from getting in your eyes. Each hair is born in a tiny hole called a follicle.

Our eyes are always the same size but our ears and nose never stop growing!
