Why don't haircuts hurt?

Because hairs are made of dead cells, for that defense you don't feel an issue. The dead hair cells are filled behind a tough, waterproof protein called keratin, as are nails, and the skin flakes that you lose daily in their million from your skin's surface. All these things are a portion of the wonderful protective overcoat that covers and guard your body.
