(clinical) questions and answers
thio-free waves - (Correct Answer) Perm that uses an ingredient other than ATG as the primary
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
reducing agent, such as cysteamine or mercaptamine.
ji ji ji ji ji ji ji
Hydrogen bonds - (Correct Answer) Very weak side bonds; that are the result of attraction between
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
opposite electrical charges. Easily broken by water or heat. Reform as the hair dries or cools.

Accounts for 1/3 of hairs total strength
ji ji ji ji ji ji ji
Salt bonds - (Correct Answer) Weak physical side bonds (cross bonds) easily broken by change in pH;
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
reform when pH balance is restored. Accounts for 1/3 of hairs total strength.

Monoethanolamine (MEA) ji
ammonia-free waves - (Correct Answer) Perms that use an ingredient that does not evaporate as ji ji ji ji ji ji ji ji ji ji ji ji ji ji
readily as ammonia, so there is very little odor associated with their use. (AMP or MEA)

Sodium hydroxide relaxers are also known as? - (Correct Answer) Lye relaxers
ji ji ji ji ji ji ji ji ji ji ji
acid-balanced waves - (Correct Answer) Permanent waves that have a 7.0 or neutral pH; because of ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
their higher pH, they process at room temperature, do not require the added heat of a hair dryer,
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
process more quickly, and produce firmer curls than true acid waves.
ji ji ji ji ji ji ji ji ji ji ji
Side bonds - (Correct Answer) Disulfide, salt, and hydrogen bonds that cross-link polypeptide chains
ji ji ji ji ji ji ji ji ji ji ji ji ji
together.
ji
keratin proteins - (Correct Answer) Long, coiled polypeptide chains.
ji ji ji ji ji ji ji ji
Silicones - (Correct Answer) Special type of oil used in hair conditioners, water-resistant lubricants
ji ji ji ji ji ji ji ji ji ji ji ji ji
for the skin, and nail polish dryers.

-GMTG is the active ingredient ji ji ji ji
pH level of Hydrogen Peroxide - (Correct Answer) 2.5-4.5
ji ji ji ji ji ji ji ji
Acid waves - (Correct Answer) Glyceryl monothioglycolate is the main active ingredient in true acid
ji ji ji ji ji ji ji ji ji ji ji ji ji ji
and acid-balanced waving lotions. It has a low pH and is the primary reducing agent in most acid
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
waves. Most acid waves also contain ATG, just like a cold wave. Although the low pH of acid waves
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
may seem ideal, repeated exposure to GMTG is known to cause allergic sensitivity in both hairstylists
ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji ji
and clients.
