The Post-Mortem Growth Of Hair And Nails: Fact Or Fiction?

No, hair and nails do not continue to grow after death. After death, the human body dehydrates, causing the skin to shrink. This shrinking exposes the parts of the nails and hair that were once under the skin, causing them to appear longer than before.

Hair and nails stop growing after death

When you die, your hair and nails completely stop growing. Many grieving families believe they see new growth of hair or nails on a dead body, and they begin to question the time of death. In an emotional time, often fraught with denial, it can be difficult for families to see the appearance of new hair or fingernails. In rare cases, your hair and nails can continue to grow about 3 micrometers after death. That’s a very tiny amount of growth — barely visible. It’s certainly not enough growth to be very noticeable unless the new growth is a very dark root below brightly bleached hair.

When we are alive, our bodies produce new cells that make our hair and nails grow. Hair tends to grow about 10.5 mm, or nearly a half-inch, per month. Fingernails and toe nails grow about 3.47 mm and 1.62 mm per month, respectively. After death, dehydration causes the skin and other soft tissues to shrink. This occurs while the hair and nails remain the same length. This change in the body creates the optical illusion of growth people observe.

No more beautiful plumage for you, ex-human. LiveScience explains that when you’ve breathed your last, there isn’t any material or hormonal activity left to induce any growth in your fingernails, toenails, or hair. When you shuffle off your mortal coil and join the choir invisible, as some marvelous chaps once said in a pet shop, your body begins to dry out. This dehydration causes your skin, as well as other soft tissues, to retract, but your hair and nails remain intact. This, then, can sometimes give the appearance of growing hair and nails post-mortem, but it’s an illusion, nothing more.

Dehydration causes skin to retract

When you die, your body begins to dry out, which causes your skin to retract. This optical illusion of growth is caused by the skin around the hair and nails retracting, while the hair and nails remain the same length.

Dehydrated skin is a skin condition caused by external elements (weather and seasonal changes), unhealthy diet (lack of fresh produce) and lifestyle choices (alcohol or caffeine consumption). All of these factors deplete your skin’s water content, resulting in a less supple appearance.

According to the Guinness Book of World Records 2018, one Ayanna Williams of Houston has nails that are 576.4 centimeters (227 inches) long, the fruits of more than two decades of peculiar patience. Clearly, if fingernails grew after death, coffins would quickly resemble wooden, elongated porcupines. It’s not clear where this myth started, but Snopes does mention that Vincent Price’s character in the 1959 movie The Tingler makes the claim.
