Why does cutting your skin hurt but not cutting your hair or nails?
There no nerves in the hair and nails
Why you do not feel pain when you cut your nails?
Because there are no nerves in your hair or nails. When you pull on them you are making the hair pull on your scalp, which contains nerves and can thus cause pain. Cutting your hair doesn't touch any nerves, so it doesn't hurt.
Why you do not feel pain when you cut your hair is because?
Because as hair is formed, it matures through a process called "keratinization", that's when the hair cells lose their nuclei. Once a cell loses its nucleus, it's no longer alive, so by the time the hair emerges from the skin, it is merely dead strands of protein. Also same with nails. == Cutting hair or nails doesn't hurt because there are no nerve endings. You can shave yourself bald or keep your nails very short. The only time you may hurt your fingers while cutting nails is if you go up into the nail bed.
