Why do we have hair?

To protect our heads :)

good question u no idk but it is used 2 look nice

Because we are mammal, and mammals have hair?

So you can have sexy hair... like mine.

So that we can have something that irritates us every single day and won't calm down so we have to put in in a ponytail and get special conditioner and it's all because our dads didn't use condoms.

What do you mean? We don't have hair...

In todays society its usually a sign of beauty and elegance. This is a pretty obvious question, its to protect ourselves from heat (strokes and seizures can be started with no hair), cold (our heads are VERY sensitive), and other everyday occurances. We also have hair everywhere on or body to lightly protect us from skin cancer and other deseases. Id have to...this is a REALLY stupid question .__." the answer is so obvious i feel stupid from just answering...

So everyone won't laugh at people being bald

to protect our heads from the MOTHERF@#$ING cold.

This question is as these questions:

-Why do we have two eyes and not only one eye?
(And don't say to look nice.)
-Why do we have two holes in our noses and not only one hole?
(And don't say to look nice.)
-Why do we have our mouths under our noses and not upon them?
(And don't say to look nice.)
-Why are our ears stuck to both sides of our heads and not to both sides of our waists?
(And don't say to look nice.)

Not to answer your question with asking questions back, but if I say that this was how we were created by god many people don't believe in god. So, yeah...
