  1. Flash Cards for Permanent Waving

  2. 1. What is the role of an alkalizing agent in the permanent waving process?

  3. ANSWER • To lift the cuticle so that the permanent wave solution (reducer) has access to the hair’s cortex

  4. 2. What is the role of the activator in the permanent waving process?

  5. ANSWER • To cause the permanent wave solution (reducer) to start working.

  6. 3. What is the role of the permanent wave solution (reducer) in the permanent waving process?

  7. ANSWER • To break the disulfide (sulfur) bonds found in the hair’s cortex.

  8. 4. What is the role of the neutralizer (oxidizer) in the permanent waving process?

  9. ANSWER • To rebuild the broken disulfide (sulfur) bonds in new positions.

  10. In the permanent waving process, the term ‘fixative’ means the same as ___.

  11. ANSWER • neutralizer, or normalizing solution (normalizer), or oxidizer, or oxidizing agent

  12. 6. What is a peptide bond?

  13. ANSWER • The major bond of hair, it is found between individual amino acids holding them together into a long chain called a polypeptide.

  14. 7. A salt bond is also known as a(n) ___ bond.

  15. ANSWER 7. Ionic

  16. 8. How does the strength of the hydrogen bond (H-bond) compare to the strength of the other hair 3 types of hair bonds?

  17. ANSWER • It is the WEAKEST of all the hair bonds

  18. 9. Which of the hair bonds are MOST sensitive to changes in pH?

  19. ANSWER 9. Ionic (salt) bonds

  20. 10. How does the strength of the disulfide cross-link bond compare to the strength of the other 2 types of cross-link bonds?

  21. ANSWER • It is the STRONGEST of the cross-link bonds

  22. 11. What is one simple way to break the hydrogen bond cross link?

  23. ANSWER • With water; just get the hair wet.

  24. 12. What is so special about the peptide bond found in hair?

  25. ANSWER 12. • It is the strongest of all the hair bonds or • It must NEVER be broken during the permanent waving process or • It is NOT a cross-link type bond

  26. 13. What is so special about the hydrogen bond cross-link found in hair?

  27. ANSWER 13. • It is the weakest of all the hair bonds or • It is the most abundant of all the hair bonds

  28. 14. How is a disulfide (sulfur) bond made?

  29. ANSWER • Between two separate sulfur atoms on two different cysteine amino acids.

  30. 15. When the disulfide cross-link bond is split it is called a ___ reaction.

  31. ANSWER 15. Reduction

  32. 16. Making their own heat to speed up processing time is one advantage of a(n) ___ perm.

  33. ANSWER 16. Exothermic

  34. 17. Which perms have the disadvantage of creating weak curls?

  35. ANSWER 17. low-pH and true-acid waves

  36. 18. What is unique about the permanent waving process for low-pH and true acid perms?

  37. ANSWER • Both are endothermicperms ….meaning they require the use of a hair dryer as a heat source to speed up processing time

  38. 19. If hair is very damaged and extremely porous a good choice of perm type to use would be a(n) ___.

  39. ANSWER 19. True acid wave

  40. 20. What is one of the disadvantages of the alkaline/ cold wave perm type?

  41. ANSWER • They have an unpleasant ammonia odor or They can be very harsh on the hair, especially delicate hair

  42. 21. What is one of the disadvantages of an acid- balanced perm?

  43. ANSWER • Repeated exposure often causes allergic sensitivity in clients and stylists

  44. 22. What kind of curl can be expected from an alkaline/ cold wave?

  45. ANSWER • The firmest, strongest curls that can be achieved by the permanent waving process.

  46. 23. An alkaline/ cold wave type of perm is a good choice for a client who has ___ hair.

  47. ANSWER 23. Resistant

  48. 24. ATG is the active ingredient in ___ perms.

  49. ANSWER • Alkaline/ cold wave or Exothermic
