Why it doesn't hurt once we cut our nails or hair but it does hurt once other body parts get hurt?

Why don't we feel pain once we cut our hair?

That's quite an interesting

Inside our body, there's 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 hair, not skills to send a message?

No. Generally, the part of our hair above the skin is formed from dead cells.

It does not have any nerves. Hence, once we cut our hair, because of the absence of nerves, our brain doesn't receive any messages of pain.

As a result, we don't feel any pain.

Our body parts get hurt because they have nerve sensations in them. So whenever we get bruised the tissues and cells within the skin get damaged and nerves send sensations to the brain.

But the parts of the hair and nails that lie about the skin's surface are made up of keratin. Keratin is comprised of dead cells of a tough protein. Since these cells are dead there is no sensitivity in them thus when we cut our hair and nails there is no sensation. that's because both hair and nails have nerve endings slightly below the skin surface

If a hair is pulled or nails are too short these nerves are affected and this could hurt us.
