Function
Vellus hair provides both thermal insulation and cooling for the body. This insulation regulates body temperature. The function of vellus hair on sweat is that of a wick. While a skin pore is open, sweat wets a strand of vellus hair. The sweat on the external part of the strand evaporates. More sweat wets the external part of the vellus strand and then evaporates. This process is perspiration.
