Topic: Nerves. Why don’t we feel pain when we cut our hair? Because if it would, then we would have got angry on our hair dressers. You are just impossible. Wait. I will explain it to you. Inside our body, there is a network of nerves. These nerves help us to sense our surroundings and feel pain, touch, etc. by sending messages to the brain. So, do the nerves of my hair not know how to send a message? No. Generally, the part of our hair above the
skin is made up of dead cells. It does not have any nerves. Hence, when we cut our hair, due to the absence of nerves, our brain does not receive any messages of pain. As a result, we don’t feel any pain.
