In brief: Genetics

Some ethnicities have more than others; within each, the amount of hair varies considerably.
Male hormones are required to express the tendency, and a woman with some extra male hormones may remain a functioning woman but have more hair than a smooth man. Some folks like more body hair, some prefer smooth; more men are now keeping it trimmed for comfort / convenience.
