Question:
What exactly is hair made of? Why do people go bald?



Replies:
Hair is mostly made of a protein called keratin that forms long chains. Proteins are chains of amino acids, organic molecules. People go bald primarily because of their genes. Of course some environmental stresses cause hair loss, such as radiation exposure. Male pattern baldness is genetic, that is heritable, and is often correlated with higher levels of testosterone in the blood.
