I have curly hair, how about you?
I have horrible thin fine straight hair, unfortunately!!! 
Haha. Whats the whole purpose of hair anyways?
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?
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?
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?
