Questions and Answers

Which type of keratin is formed during the process of permanent waving?

  • Delta-keratin
  • Beta-keratin (correct)
  • Alpha-keratin
  • Gamma-keratin

    • Which of the following is the correct explanation for the changes in hair wave appearance during the process of permanent waving?

  • The cooling or oxidation process causes the disulfide bonds in alpha keratin to reform as beta-keratin, resulting in a change in wave appearance. (correct)
  • The moist heat conditions cause the hair to stretch, resulting in a change in wave appearance.
  • The reduction of disulfide bonds in alpha keratin using a reducing agent causes the hair to become permanently waved.
  • The breakage of disulfide bonds in alpha keratin using moist heat causes the hair to become permanently waved.

    • What is the role of moist heat in the process of permanent waving?

  • Moist heat breaks the disulfide bonds in alpha keratin, allowing them to reform as beta-keratin.
  • Moist heat has no role in the process of permanent waving.
  • Moist heat reduces the hair's elasticity, making it easier to manipulate during the waving process.
  • Moist heat causes the hair to stretch, resulting in a change in wave appearance. (correct)
