Your hair is made of the same
material as your nails,as a horse's hoof,as a reptile's scales,and as a bird's
claws and feather.If your hair or any parts of these animals is cut,there is no
pain because your brain only receives "pain messages" from parts of your body
that have nerve endings.Since there are no nerve endings in your hair, no
messages can be sent to your brain and you feel no pain when it is cut.
