A chimp has no more individual hairs than a human. While the texture of the hair on the human body is much finer and less visible to the naked eye, it is actually about the same amount of fur as on a chimp. It is thought that perhaps humans originally had a thicker coat of fur that may have served as protection, but it eventually receded over time as it began to be less necessary for survival. Evolutionary theories as to why humans’ body hair became finer include making it easier to sweat, as well as to make parasites and lice less of a nuisance.
