Haha. Whats the whole purpose of hair anyways?
1_Wizard
from an evolutionary standpoint, I suppose it's to keep us from freezing. they're now able to identify murder victims from DNA taken from hair strands, not just follicles!

What are they made from?
1_Wizard
DNA, or hair strands? Hair i believe is mostly protein...actually so is DNA! Or parts of it anyways.

Very interesting. So why do some men lose their hair?
1_Wizard
Poor genetics...I believe it's usually whatever is passed down on the X chromosome from the mother's father. Or something like that...and yes I was a science major! what did you study?
