Why do we have hair? Whats the purpose of hair? Well First off Hair is important to our health. The reason we have hair on our head is to protect our head from sunburn and overexposure to the sun. Hair also helps with insulation of heat during the winter. A major part of our heat in our body escapes from our head. Our eybrows and lashes are used as a defensive use. Eyebrows catch the sweart beads that could impair our vision. Eyelashes catch dangerous particals in the air preventing eye damage.
