Question

why dont we feel pain when we cut our hairs and nails??
​

Answer 1

we don't feel any pain because our hair has no nerve endings

also,there is no sensory nerve in nails

Answer 2

Since hair and nails do not have nerve endings, cutting them does not produce pain. However, cells at the base of a nail and hair are living cells and have nerve endings.

So, if a nail is cut from the base or if a hair is plucked off, pain is felt.

hope it helps you.
