WHY does our hair get frizzy? Let's look at our genetic roots, since they are the ones who decide whether our hair will be straight, wavy, or curly. If we were in chemistry class right now, we would see under a microscope that
hair is made up of braided protein chains of keratin. These, in turn, contain sulfur atoms - sulfides, when joined together forming a disulfide bond.
It is this bond that is responsible for the bending of the hair. The fact is that curly hair is rich in disulfide bonds, while straight hair is not.
