testosterone... some women have too much and grow facial hair too... this seems to be prevalent among east indians...Why do Men have facial hair and women dont?
A good question! The occurrence of male facial hair, like any physical trait or behavior, may be explained from four different, complementary perspectives or ';levels of analysis.'; Two provide ';proximate'; (immediate cause) explanations, and the other two provide ';ultimate'; (long-term cause) explanations. Proximate explanations describe developmental programs and physiological mechanisms, whereas ultimate explanations focus on how traits affect survival and reproduction, and their probable evolutionary history.
Let's consider your question from all four perspectives. Regarding development, male facial hair sprouts at puberty (sexual maturity), coincident with emergence of a suite of ';adult'; characteristics, such as increases in height and deepening of the voice. Regarding mechanism, appearance of facial hair, and the other signs of maturity, are attributable to the stimulatory effects of male hormones, particularly testosterone.
Regarding evolutionary history, varying amounts of facial hair occurs in all primates (our closest relatives), and its quantity and quality differ between the sexes in many species. This implies that sexual dimorphisms in facial hair have characterized our evolutionary lineage for millions of years.
What about the functions of facial hair? Clearly it is not necessary for survival or reproduction, since it does not occur in most women and it is minimal or absent among men in many populations. Such variations seem unrelated to climate or ecology.
Most likely, facial hair functions in ';sexual selection,'; meaning attracting mates or intimidating rivals. For example, a beard's color and texture are known to influence womens' perceptions of a man's age, social status, and general vigor. A bushy beard also may make a man appear larger, cushion his face against blows in a fight, and hide scars from previous altercations.
Men in our culture routinely shave off their facial hair. Does this imply that beards are no longer attractive or protective in societies like ours? Perhaps you'll find out!
The answer to men's facial hair is the hormone ';testosterone';. This hormone, which males produce even since birth, becomes fully active during and after puberty. Facial hair is just one side effect of testosterone; it stimulates many different types of bodily/pubic hair. It also stimulates some parts in male growth.
Maybe when women started to not go outside of the cave as much, they needed facial hair less. Maybe men found women's faces sexually stimulating, hence encouraging the evolution of smooth-faced women.(鈩?Mistress Bekki anwser
thats the same as why do men have a penis and women dont. its all down to the way the human race was brought up.

facial hair is genetic and depends on hormone and testosterone levels, so some men will have it, some don't. AND some women will have it.
Look man soon enough you'll see that women get hair on their leg, armpits, arms, vagina, and even mustaches. But most shave and get waxes. Look around and research I promise you. Anything else? Call ya boy D up @ rashadlove77@yahoo.com.
testosterone is the male hormone which makes men do and like ';men things'; eg. grow facial hair. women have a different hormone called estrogen which makes the women do ';women things';
All people have facial hair, both men and women. But men's hair is much thicker because of the amount of male hormone called testosterone.
hormones, and woman with unbalanced hormone levels.....lets just say i've seen some woman who needed desperate waxing, not only for their eyebrows .....
Hormones and testosterone and body thingies
Basically, it is the same reason the male lions have manes and lionesses do not.
I don't think EVERY male gets facial hair. I know a few people going on 20 years old that don't have any.
Testosterone.
I blame testosterone.
I'm 13 and I have really hairy legs and arms for my age.
More Testosterome in the Male, most of the time.
probably something to do with tetosorone or hormones
I have seen quite a few women with facial hair. It is scary.
hormones
and normal ppl ya
im pretty sure its their testosterone
because guys produce testosterone and girls dont
I've seen a few women who do, we used to call one of them Butch.
