The Malleability and Elasticit
I. Introduction
As result of genetic differentiation, every single person in the world has distinct hair, but the main differences between hair types are in texture and thickness. These variations are caused by the genetic make up of the fibers that make up the hair and follicles that generate the fibers. Hair is made from keratin (protein) that is wound in a coil.
