EXAM REVIEW QUESTIONS WITH
CORRECT ANSWERS
Instant Moisturizer - Answer-Helps replace natural moisture and oils lost during
chemical processes
How many steps are in curl reformation - Answer-2 steps
How many times do you unwind a curl for a curl test - Answer-1/1.2
exterior length - Answer-Bottom
Interior length - Answer-On top
Volume indentation - Answer-Brush is positioned underneath
indentation - Answer-Brush is positioned on top of hair strand
Resistant porosity - Answer-The cuticle layers are smooth, tightly packed and compact.
Average porosity - Answer-Cuticle is slightly raised
Extreme porosity - Answer-The cuticle is lifted or missing
Overprossed hair - Answer-Curlier at the scalp and straighter at the ends
Underprocessed Hair - Answer-HAIR STRAIGHT AT SCALP AND CURLY AT ENDS
Sodium Hydroxide is - Answer-Alkaline
sodium hydroxide oils applied to - Answer-Tightly curled hair
Sodium hydroxide ph - Answer-11.5-14
Metallic Salts Test - Answer-1oz 20-volume peroxide, 20 drops 28% ammonia, immerse
20 hair strands for 30 minutes. if hair lightens rapidly it has metallic salts
Thioglycolic acid - Answer-A colorless liquid with a strong unpleasant odor that is used
in permanent waving solutions. Common reducing agent
ammonium thioglycolate (ATG) - Answer-Active ingredient or reducing agent in alkaline
permanents.
, 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
True acid waves - Answer-Have a pH between 4.5 and 7.0 and require heat to process;
they process more slowly than alkaline waves, and do not usually produce as firm a curl
as alkaline waves.
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.
glyceryl monothioglycolate (GMTG) - Answer-main active ingredient in true acid and
acid-balanced waving lotions
Aminomethylpropanol ( AMP) and Monoethanolamine (MEA) - Answer-Two substitutes
for ammonia in an ammonia-free wave
thio relaxers - Answer-Use the same ammonium thioglycolate (ATG) that is used in
permanent waving, but at a higher concentration and a higher pH (above 10). Breaks
disulfide bond
Thio neutralization - Answer-The process of stopping a permanent wave and reforming
the hair into its new curly shape
Lanthionization - Answer-Process by which hydroxide relaxers permanently straighten
hair; they remove a sulfur atom from a disulfide bond and convert it into a lanthionine
bond.
reduction reaction - Answer-a chemical change in which electrons are gained, either by
the removal of oxygen, the addition of hydrogen, or the addition of electrons
Acid perms have a ph of: - Answer-6.9-7.2
Alkaline perms carry a pH of: - Answer-8.0-9.5
Alkaline perms also known as - Answer-Cold perm
Alkaline perm main ingredient - Answer-Ammonium thioglycolate
Alkaline perm are used on - Answer-Coarse virgin resistant hair
Alkaline perms produce - Answer-Strong curl pattern
