Humans are a remarkably diverse species, with a wide range of physical characteristics. One of the most noticeable differences between men and women is the length of their hair. In general, women have longer hair than men. This difference is not simply a matter of fashion; it is rooted in biology and evolution.
There are several reasons why women have longer hair than men. One reason is that hair helps to protect the head from the elements. Long hair can help to keep the head warm in cold weather and cool in hot weather. It can also protect the scalp from the sun's ultraviolet rays.
