Hair helps to protect the scalp from UV radiation and provides insulation. Nails protect the fingertips and enhance tactile sensations.

No, nails are not bones. Nails are made of a protein called keratin, while bones are rigid organs that make up the skeletal system. Bones provide structure and support to the body, whereas nails protect the ends of the fingers and toes.

Hair and nails are composed of keratin, a protein that does not have nerve endings or blood supply, making them insensitive to pain. When you cut hair or nails, you're essentially trimming dead tissue, which does not trigger pain receptors in the body. In contrast, the skin and underlying tissues, which do have nerve endings, can feel pain when injured. This lack of sensation in hair and nails is why grooming them does not cause discomfort.
