Hormones: They are artificial synthetic additives like steroids that unnaturally help to boost hormones in the body for a specific function. They can be found in our everyday food or even in some cosmetic / pharmaceutical by products.
Hormones called androgens are the main reason that body hair develops. Doctors refer to androgens as male hormones, though both men and women produce them. When the female body produces too many androgens, it may develop more body hair than is typical.
