(CLINICAL) EXAM QUESTIONS AND
ANSWERS 100% ACCURATE!
thio-free waves - ANSWER Perm that uses an ingredient other than ATG as the primary
reducing agent, such as cysteamine or mercaptamine.
Hydrogen bonds - ANSWER Very weak side bonds; that are the result of attraction
between opposite electrical charges. Easily broken by water or heat. Reform as the hair
dries or cools. Accounts for 1/3 of hairs total strength
Salt bonds - ANSWER Weak physical side bonds (cross bonds) easily broken by
change in pH; reform when pH balance is restored. Accounts for 1/3 of hairs total
strength.
Substitutes for ammonia in permanent waving solutions: - ANSWER
Aminomethylpropanol (AMP)
Monoethanolamine (MEA)
ammonia-free waves - ANSWER Perms that use an ingredient that does not evaporate
as readily as ammonia, so there is very little odor associated with their use. (AMP or
MEA)
Glycerol monothioglycolate - ANSWER Main active ingredient in acid balanced waving
lotions. Primary reducing agent in most acid waves. Low pH
Sodium hydroxide relaxers are also known as? - ANSWER Lye relaxers
acid-balanced waves - ANSWER Permanent waves that have a 7.0 or neutral pH;
because of their higher pH, they process at room temperature, do not require the added
heat of a hair dryer, process more quickly, and produce firmer curls than true acid
waves.
Side bonds - ANSWER Disulfide, salt, and hydrogen bonds that cross-link polypeptide
chains together.
keratin proteins - ANSWER Long, coiled polypeptide chains.
