The cortex layer of the hair structure is responsible for the hair's length and texture.
the term pH is an abbreviation used for potential hydrogen.
The single flat wrap uses one end paper folded in half over the hair ends like an envelope.
On-base placement minimizes stress and tension on the hair.
alkaline waves are also known as cold waves.
Ammonia-free waves use an ingredient other than ATG, such as cysteamine or mercaptamine.
the most common neutralizer is hydrogen peroxide.
the curvature permanent warp uses zigzag parting to divide base areas.
Japanese thermal straightening combines use of a thing relaxer with flat ironing.
Keratin straightening treatments work by breaking side bonds.
The process of chemically altering the natural wave pattern of hair is:
chemical hair softening
chemical texture services
natural hair services
alternative texture services
The range of numbers used in the pH scale is:
0 to 5
0 to 7
0 to 10
0 to 14
Chemical hair texturizers temporarily raise the pH of the hair in order to:
expand and harden the shaft
harden and close the shaft
swell and set the shaft
soften and swell the shaft
In the resturctureing process, coarse, resistant hair with a strong compact cuticle require a chemical solution that is:
slight alkaline
mildly acidic
strongly acidic
highly alkaline
chemical side bonds formed when two sulfur-type chains are joined together are:
disulfide bonds
peptide bonds
keratine bonds
amino bonds
In permanent waving, the shape and type of curl are determined by the shape and type of rod and the:
long rods
hair length
sectioning
wrapping method
Rods that are equal in diameter along their entire length or curling area are
convex rods
straight rods
conventional rods
spiral rods
The wrapping technique that provides the most control over hair ends is the
single flat wrap
bookend warp
double flat wrap
placed wrap
All perm warps begin by sectioning the hair into
subsections
base sections
parts
panels
In permanent waving, panels of hair are divided into smaller subsection called
rod sections
outer sections
placements
Caution should be used with on-base rod placement to avoid additional:
sectioning of hair
stress and tension on hair
increased volume
curl patterns
The angle at which a permanent wave rod is postioned on the head is reffered to as
wrapping technique
rod direction
diagonal technique
base direction
The two methods of wrapping the hair around a perm rod are:
flat and spiral
croquignole and even
spiral and perpendicular
croquignole and spiral
In the croquignole method of wrapping, the hair is wound from:
scalp to ends
longest to shortest
ends to scalp
shortest to longest
Once in the cortex, the waving solution breaks the disulfide bonds through a chemical reaction called:
rearranging
normalization
reduction
alkaline
In permanent waving, the reduction reaction is due to the addition of:
hydrogen
oxygen
salt
carbon
The active ingredients or redution agent in alkaline permanent waves is:
ammonium thioglycolate
hydrogen thioglycolate
alkaline acids
glyceryl monothioglycolate
Most alkaline permanent waves had a pH between
4.5 and 5.5
6.0 and 7.0
9.0 and 9.6
10.0 and 11.0
The main active ingredient in true acid and acid-balanced waving lotions is:
glyceral monothioglycolate
ammonium thioglycolic
sodium hydroxide
sodium hydrochloride
All acid waves have trhee components sonsisting of the permanent waving lotion, neutalizer, and:
conditioner
prewrap
stabilzer
activator
Exothermic waves create a chemical reaction that heats the waving solution and speeds up:
processing
conditioning
neutralizing
formulation
Waves that are activated from an outside heat source are considered:
stablized
endothermic
exothermix
acid waves
Hair that has to many disulfied bonds broken and will not hold a firm curl is considered:
underprocessed
overprocessed
underneutralized
tinted
The process that stops the action fo permanent wave solution and rebuilds the hair into its new form is:
rinsing
thio neturalization
Base cations are ofset from each other row by row, to prevent notciable splits, in which wrapping pattern?
weave technique
bricklay permanent wrap
basic permanent wrap
straight wrap set
The double-rod wrap technique is also called the:
piggyback warp
straight wrap
spiral wrap
The process of rearranging the basic structure of curcly hair into straight or smother form is
texturizing
permanent waving
chemical softening
chemical hair relaxing
Hydroxide relaxers remove a sulfur atom from a disulfide bond, converting it into a(n):
normalization bond
acidic bond
lanthionine bond
amino bond
Relaxers that contain only one component that are used without mixing are:
neutralizing relaxers
metal hydroxide relaxers
guanidine hydroxide relacers
calcium hydroxide relaxers
Sodium hydroxide relaxers are commonly called
metal relaxers
no-lye relaxers
lye relaxers
medium relaxers
relaxers are often marketed and sold as no mix-no lye relaxers are
potassium hydroxide relaxeres
sodium hydroxide relaxeres
ammonium thio relaxers
guanidine hydroxide relaxeres
relaxers that contain two components and must be mixed immediately prior to use are
hydroxide relaxers that do not require the application of a protective base are
no-base relaxers
base cream relaxers
bream relaxers
The difference in the strength of most chemical hair relaxers is determined by the concentration of
lanthionization
hydroxide
ammonia
coating
During a relaxer strand test, hair that is pressed to the scalp and continues to curl is
sufficiently relaxed
insufficiently relaxed
normalized
The application of chemical relaxers should be started in the most resistant area, usually the
back of the head
front hairline
scalp area
side area
Conditioner with an acidic pH that restores the hair's natural pH after a hydroxide relaxer is:
lanthionization solution
natural lotion
swelling cream
normalization lotion
A combination of a thio relaxer and a thio permanent wrapped on large rods is a:
permanent wave
soft curl permanent
furl curl permanent
relaxer retouch
Chemical services shoudl not be performed if the scalp analysis shows any signs of
porosity
abrasions
disorder
tightness
Hair that is treated with hydroxide relaxers must not be treated with:
conditioning solutions
color shampoos
thio relaxers
normalization solutions
