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.
Silicones - ANSWER Special type of oil used in hair conditioners, water-resistant lubricants for the skin,
and nail polish dryers.
Alkaline waves - ANSWER also known as cold waves; have a pH between 9.0 and 9.6, use ammonium
thioglycolate (ATG) as the reducing agent, and process at room temperature without the addition of heat
Permanent waving - ANSWER a two step process whereby the hair undergoes a physical change caused
by wrapping the hair on perm rods and then hair undergoes a chemical change caused by the application
of permanent waving solution and neutralizer
polypeptide chain - ANSWER long chain of amino acids linked by peptide bonds
peptide bond - ANSWER Bonds that connect amino acids.
Alkanolamines - ANSWER Alkaline substances used to neutralize acids or raise the pH of many hair
products.
Used in place of ammonia because it produces less odor.
low-pH waves - ANSWER Perms that use sulfates, sulfites, and bisulfites as an alternative to ammonium
thioglycolate; they have a low pH.
