Why we feel no pain while cutting our nails and hairs?

coz these are dad

Nails and hairs are not having blood at the end of them.

The part of the nail and the hair that you cut are not alive; the hair follicles at the root of the hair and the nailbeds are the live parts that nourish the hair and nails. That's why if you pull a hair at the root or if a nail is torn off it hurts, because that is the area with the blood flow and nerve endings.
