Long and strong nails, who wouldn’t want that? Still, many people occasionally suffer from yellow, bluish, or chipped nails. But what do nails actually say about your health? And how do you best take care of your nails? We tell you all about nails!
What are nails and what are they made of?
Nails are made of the protein type keratin. This is dead tissue. Therefore, there is no feeling in your nails. Nails nevertheless grow. This is because the new cells that are created push the nail forward. Nails protect the tips of the fingers and toes. There are a lot of nerve endings in your fingertips. Without nails, your fingers and toes would be very sensitive.
