Mainly, it keeps you warm. because it's pretty(sometimes) It traps heat in the body when it's cold and lets heat out when it's warm. -------------------------------------------------- Hair has many uses on top of that. Hair in the nose and ears work to keep bacteria from entering the body. Short hairs on your hands and arms give you a first detection as something lands on the arm. (for instance a mysquito lands on your arm, it moves the hair sending a signal down the hair folicle, stimulating the free nerve endings and sending a signal to the brain that something has moved your arm hair. Tiny hairs inside the body called cillia or microvilli depending on their location and size move things around in your body. For instance in your lungs there are cillia that move foreign materials up and out of the lungs where you then cough it up or swallow it killing most materials that would enter your lungs. besides fashion, and the little bit of warmth it provides, not much, it is a holdover from our much hairier beginnings.
the 3 functions of hair

  • protect the skin from the sun
  • keeps dust and insects out of your nose and eyes
  • regulates body temps.

it releases the extra pigments in your body. and makes you look sexy

plus im not the person who wrote that ^ but whoever did it AWESOME ^
skin protects your insides from being harmed or damaged.

your nails are there to protect that soft part of your skin.

and your hair protects your skin. because we are all secretly monkeys. That is also why we smell bad.
