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.
When a hydroxide relaxer breaks the disulfide bond
converting them to lanthonine bonds.... - answer The
bonds cannot be reformed with any other chemical
treatment
, True acid waves - answer -Have a pH between 4.5-7.0 and
require heat to process.
-He process slower than alkaline waves
-GMTG is the active ingredient
pH level of Hydrogen Peroxide - answer 2.5-4.5
Acid waves - answer Glyceryl monothioglycolate is the
main active ingredient in true acid and acid-balanced
waving lotions. It has a low pH and is the primary reducing
agent in most acid waves. Most acid waves also contain
ATG, just like a cold wave. Although the low pH of acid
waves may seem ideal, repeated exposure to GMTG is
known to cause allergic sensitivity in both hairstylists and
clients.
Lanthonization - answer The process by which a hydroxide
relaxer removes one atom of sulfur from a disulfide bond.
Volatile organic compounds - answer Compounds
containing carbon that evaporate easily.
ex.) SD alcohol (ethyl) in hairspray
Used in nail polish, base & top coat & polish removers
Ammonia - answer Colorless gas with pungent odor
composed of hydrogen & nitrogen. Used to raise pH in hair
products to allow solution to penetrate hair shaft.
