Keratin in hair has disulfide bridges. When hair undergoes apermanent wave, whereby the once straight hair is curled, it isfirst reduced (step 1), curled (step 2), and then oxidized (step3). Why is this protocol necessary for the permanent wave to besuccessful? Write the purpose of the step on the lines provided.Use the diagram below to help construct your argument. (Limit youranswer to 1 sentence per step). Step 2 has already beenprovided.
