Answer:
-A disulfide bond joins the sulfur atoms in two adjacent polypeptide chains.
-Permanent wave solution breaks a disulfide bond by adding a hydrogen atom to each of its sulfur atoms.
-The sulfur atoms attach to the hydrogen atom from the permanent waving solution, breaking their attachment to each other.
-Once the disulfide bond is broken, the polypeptide chains can form into their new curled shape. Reduction breaks disulfide bonds and oxidation reforms them.
