It is a common belief that hair and nails continue to grow after death. This belief has been perpetuated by various sources, including literature, Hollywood movies, and even old tales of vampirism in Europe. While it is true that hair and nails can appear longer after death, it is not because they are growing. Instead, the flesh shrinks as it dries out, retracting the skin and exposing more of the nail bed and hair that was previously not visible. In rare cases, there may be some minimal growth of hair and nails after death, estimated at around 3 micrometers, due to some cellular functions that create keratin continuing for a short time until the cells run out of glucose. However, this amount of growth is barely visible and does not support the idea of continuous growth.

What You'll Learn
The myth of nails growing after death is pervasive in popular culture
The idea that hair and nails continue to grow after death is a pervasive and enduring myth. It is a concept that has fascinated humanity for centuries, permeating popular culture and our collective imagination. From tales of vampirism in Europe to rural Slavic nations, the image of a corpse with ever-growing nails and hair has long captured the public's interest.
This belief is so pervasive that grieving families often question the time of death, convinced that they see new growth on their deceased loved ones. However, this perceived growth is merely an illusion. While death is not instantaneous, and certain cells can survive for a short period after brain death, it is not enough to sustain the growth of nails or hair. In rare cases, nails and hair may continue to grow by a minuscule amount, approximately 3 micrometers, due to some residual cellular functions creating keratin. But this growth is barely visible and certainly does not match the exaggerated image often portrayed in popular culture.
The myth of post-mortem nail and hair growth can be attributed to several factors. Firstly, the retraction of the skin and cuticles due to dehydration and the cessation of the circulatory system creates the illusion of growth. As the flesh dries out and shrinks, more of the nail bed is exposed, making the nails appear longer. Secondly, in the case of painted or coloured nails, the difference in appearance between the coloured nail and the exposed nail bed can further enhance the perception of growth.
The enduring nature of this myth is evident in its prevalence in popular culture. Erich Maria Remarque's novel, "All Quiet on the Western Front," vividly describes a deceased character's nails growing into corkscrews. Additionally, the 1959 movie "The Tingler" also perpetuates this belief. The association between long nails and hair and vampires, as depicted by Hollywood, further cements the idea in popular consciousness.
Despite the pervasive nature of this myth, it is important to emphasize that nails and hair do not continue to grow after death. While the body undergoes changes during the decomposition process, including dehydration and retraction of the skin, these changes do not result in the growth of nails or hair.

The myth may have stemmed from old tales of vampirism in Europe
It is a widely held belief that hair and nails continue to grow after death. This belief is perpetuated by the illusion of growth, which is caused by the retraction of the skin as the body dries out, exposing more of the hair and nails. While this phenomenon is a well-known fact today, it was not always so. In the past, particularly in the 1800s, the appearance of new hair or nails on exhumed bodies was often linked to old tales of vampirism in Europe.
Vampires, as depicted in European folklore, are undead creatures that often visited their loved ones and caused mischief or deaths in the neighbourhoods they once inhabited. They were usually described as bloated, with ruddy or dark skin, and clad in the linen shrouds they were buried in. One of the most distinctive features of vampires was their long nails, which they used to scratch at their caskets and bite innocent people. These characteristics were attributed to the drinking of blood, with blood often seen seeping from the mouth and nose.
The belief in vampirism and its associated characteristics arose from mass hysteria and pre-existing folk beliefs in Southeastern and Eastern Europe, particularly in Slavic nations. It was believed that any corpse jumped over by an animal, especially a dog or a cat, would become one of the undead. This led to the practice of staking corpses through the chest and cutting off their heads to stop the spread of disease.
The idea of growing nails and hair on a corpse further fuelled the vampire myth, with stories arising of mythical vampires roaming dark countrysides, their nails growing longer as they scratched at their coffins. As science, literacy, and medicine have advanced, we now know that nail and hair growth after death is extremely minimal, if it occurs at all. In rare cases, hair and nails can continue to grow by about 3 micrometers after death, which is barely visible.
The persistence of the vampire myth in popular culture, such as Dracula and other Hollywood depictions, continues to influence our fascination with the idea of growing nails and hair after death. However, it is important to distinguish fact from fiction, as the reality of nail and hair growth after death is far less dramatic than the mythical tales of vampirism that may have stemmed from rural Slavic nations in Europe.

Nails are made of a protein called keratin
It is a common misconception that nails continue to grow after death. While nails and hair may appear to grow, this is because the skin dehydrates and shrinks, making the nails and hair appear longer. There is a small amount of truth to the idea that nails grow after death, as the death of an individual is not instantaneous. When the heart stops beating, the brain cells die very quickly, but cells that use less oxygen can survive a little longer. Therefore, nails may grow a tiny amount—approximately 3 micrometers—after death. This growth is barely visible, and is far less than the average nail growth rate of 0.1 mm per day in healthy adults.
Keratin treatments and products are available to help strengthen hair and nails. These treatments can make hair look brighter and feel softer, as well as reduce frizz. Similarly, nail treatments containing keratin can help strengthen nails, prevent cracking and chipping, and promote healthy growth. These treatments are absorbed into soft, weak nail layers to provide maximum strength.

Nails grow by an average of 0.1mm per day
It is a common misconception that nails continue to grow after death. This belief is likely fuelled by the appearance of longer nails and hair on corpses, which occurs due to dehydration and the retraction of skin around the nail bed. In reality, nails grow by an average of 0.1 mm per day, a rate that slows as we age. This growth is dependent on the production of new cells, which cannot occur without glucose, and the brain typically dies within three to seven minutes of the heart stopping.
The circulatory system no longer pumps blood to the cuticles after death, causing them to retract and expose more of the nail bed. This phenomenon, combined with the drying out of the flesh, creates the illusion of growing nails. In rare cases, nails can continue to grow by about 3 micrometers after death, but this is barely visible. To put it into perspective, one human hair is approximately 100 micrometers wide, so this growth would be equivalent to around 1/33rd of the width of a hair.
The idea of nails continuing to grow after death has been a source of fascination and horror, with references in popular culture and literature, such as Erich Maria Remarque's novel, "All Quiet on the Western Front". However, it is important to note that nails do not continuously grow, and the belief that they do is a pervasive myth.
The appearance of growing nails and hair on corpses has even been linked to old tales of vampirism in Europe, with long nails being a crucial part of a vampire's appearance. Historically, in rural Slavic nations, exhumed bodies with apparent nail and hair growth were believed to be spreading disease, leading to the decapitation and staking of the corpses to stop the perceived spread of illness.

The appearance of nail growth after death is due to the retraction of the skin
It is a common belief that hair and nails continue to grow after death. This belief is perpetuated by the observation of hair and nail growth on corpses. However, this is a misconception. Nails and hair do not grow after death; instead, the appearance of growth is due to the retraction of the skin.
When a person dies, their circulatory system stops functioning, and blood no longer flows to the cuticles. This causes the cuticles to retract, exposing the nail beds and making the nails appear longer. Similarly, the hair follicles can become more visible as the skin dries out and shrinks. This phenomenon is known as livor mortis, and it creates the illusion of growing hair and nails.
The belief in post-mortem nail and hair growth is not new. Historical anecdotes and descriptions from medical students working with cadavers have contributed to this idea. Additionally, old tales of vampirism in Europe often associated vampires with long nails and hair, further perpetuating the misconception.
While nail and hair growth after death is primarily an illusion, there is a small degree of truth to it. Death is not instantaneous, and while brain cells die quickly once the heart stops beating, cells that require less oxygen can survive a little longer. This means that, in rare cases, hair and nails can continue to grow by a minuscule amount after death. This growth is approximately 3 micrometers, which is barely visible and equivalent to about one-third of the width of a human hair.
In conclusion, the appearance of nail growth after death is primarily due to the retraction of the skin and exposure of the nail beds, rather than actual nail growth. While there may be a minuscule amount of genuine growth due to the lingering survival of certain cells, it is not significant enough to be noticeable.
