The main body of the hair shaft is known as the cortex. This is actually made up of spindle-shaped cortical cells that are aligned in a regular array parallel to the length of the hair.
Hair is made from keratin as are most of the cortical cells. Keratin is a protein that is helical. There are two different types of fibers that exist in hair and they are keratin fibers. Type I with acidic amino acid residues and type II with basic amino residues.
