- The alpha-keratin of hair is rich in the amino acid cysteine. The location of these cysteines in the protein chain is genetically determined. As a result of the location of the cysteines in the protein, a person may have curly, wavy, or straight hair. How can the location of cysteines in a-keratin result in these different styles of hair?
