Your nails, your hair and the top layer of your skin are all made from the same stuff – keratin. In their own ways, they all protect your body.
Nails are made up of dead cells, which is why it does not hurt when you cut your nails. They help to look after your fingers and toes. They are also very useful in other ways, such as helping you to pick up small things or scratch different parts of your body.
Did you know?
Our nails grow about a millimetre every ten days and grow faster in summer than in winter.
