After death, nails and hair continue to grow.
The eerie idea that hair and nails continue to grow after death has been a source of fascination and horror for centuries. However, this phenomenon is a myth rooted in misunderstanding. After death, the body’s cells stop functioning, and the processes that support growth come to a halt.
What creates the illusion of postmortem growth is the dehydration of the skin. As the skin shrinks and retracts, it exposes more of the hair and nails, making them appear longer. This optical illusion has likely contributed to the myth, but in reality, hair and nails require nutrients from the blood supply to grow, and these processes cease shortly after death.
Understanding the science behind this myth removes some of the mystery surrounding death and highlights the importance of separating fact from fiction in our perception of the human body.
