In our body, there are structures like hair and nails that do not cause pain when cut. How is this possible? Our hair and nails grow as structures enriched with a protein called keratin. The growth areas of these structures are the root of the hair and the white part of the nails. A transformation process known as keratinization continuously renews the cells in these areas. When cut, the cut parts are already made of dead cells; hence they are not connected to nerve endings and no pain is felt.
Nail Cutting and Precautions
However, if you cut too deep during nail trimming, it can damage living tissue and be quite painful. Therefore, it is important to be careful when trimming nails. Our hair and nails not only serve aesthetic purposes but also protect the body from heat and impacts.
