Is this right that hairs and nails grow after death?

There is a misconception among people that hairs and nails remain growing after death of a person. The answer to this sticky question is very simple that is “No”. The hairs and nails stop growing after death.


Short Answer

The right answer is “No”. If the answer in “No”, then why hairs and nails appears larger in size than the normal one after death!


Here is the detailed answer

When a person declared as dead some of the body parts still have life. When the heart stops breathing and a person passed away and his soul is no more in his body. Still some of the body are alive and continue functioning to a limited time. Different body parts live for a different time period after death of a person. Detail of functions of some of organs is given below.


Nerve Cells or neuron

Neurons or nerve cells are the only cells that die quickest in a few minutes. After heart stop breathing the nerve cells ceases to communicate with each other and after some time the brain degenerate. Scientists stated that nerve cells take glucose from the blood and use those glucose molecules as food. When the heart stops working and there is no flow of blood to brain. The nerve cells no more receive oxygen and glucose and they starts dying. (Keep in mind that for the production of energy from glucose oxygen is necessary.

Oxygen helps in breakdown of glucose and produces energy for body cells during respiration process). When the blood supply stop almost all of the nerve cells die in duration of approximately three (3) to seven (7) minutes. The nerves work for a limited time because some amount of energy is present and when the amount of energy finishes the brain stop working. (Source ripleys).


Kidney, Liver and Heart

Kidney, liver and heart remain alive in the body in a normal condition for about half hour or thirty minutes. So the transplant experts remove all these organs under thirty minutes and get them into the recipient body (The person that receives the organ) in next six (6) hours. (Source BBC)


Nails and Hairs

The skin cells remains alive for some hours (Approximately 12 hours) and they supply some food to the hairs and nails. As a result there is some increase in size of the nails and hairs. The increase in size may be about 0.5 millimeter in hairs and 0.1 millimeter in nails as the nails and hairs grow at the rate of above mentioned in 12 hours duration. But we people normally observe more growth.

Is it right? Of course it is right. When a person die, dehydration of the skin takes place that results in the shrinkage of skin cells and tissues. As the skin shrink it pull the hair and nail outward and we call it growth. It is not growth. The cells and tissues of the body nails and hairs are at the same size but only the skin pulls it outward and we think that the increase in size occur. Actually the nails and hairs remains the same in size.



Old stories stated that nail and hairs grow after death. It is not right and is a misconception. There is no biological evidence. Biology simply explain that after death most of the functions of an individual stopped. As there is no blood flow in the body so oxygen is not available to each and every part of the body. And as a result there is no possibility of growth in the body parts. A limited growth in nails and hairs occurs but the growth is less and difficult to observe. There is no increase in size of hairs but only the skin shrink that results in the pulling of hairs outside the skin. Similar is the case of nails.


My Own Experience

When I heard about this unique concept from people. I really feel shocked.  And I decided to research on this topic. After studying a lot of articles and observing physically, I got the point that there is no increase in size or very limited increase that cannot be observe.
