The chemical texture service that loosens overly curly hair into loose curls or waves is:
curl re-formation
All chemical texture procedures involve changing the hair structure using"
chemical and physical changes
The exterior hair structure layer that protects the hair from damage is the:
cuticle
The layer of the hair that provides strength and elasticity is the:
cortex
Hair bonds that cannot be broken by heat or water are:
disulfide bonds
The natural pH of hair is between:
4.5 and 5.5
One of the most important parts of a successful texture services is the:
client consultation
Permanent waves cannot be performed if the hair is coated with:
metallic salts
Disulfide bonds are chemical-based side bonds that are formed when:
sulfur atoms in two adjacent protein chains are joined together
The measurement used to determine the hydrogen ions in a solution is:
potential of hydrogen
Chemical texturizers temporarily raise the pH of hair by lifting the cuticle layer to:
allow penetration to the cortex layer
Long, coiled polypeptide chains that are part of the hairs structure are:
keratin proteins
The client record card should include a complete evaluation of length, texture, color and:
condition of the hair
During the hair and scalp analysis procedure, the stylist should look for:
abrasions or signs of scalp disease
Hair texture that requires a longer processing or rewetting of solution to ensure complete saturation is:
coarse-textured hair
The measurement of the number of hairs per square inch on the head is:
density
An indication of the strength of the side bonds is:
elasticity
The second process of a permanent wave is the:
chemical change process
In permanent waving, the size of the curl is determined by the:
size of the rod
The permanent wave rod that produces a uniform curl along the entire width of the strand is a:
straight rod
A wrapping technique using two endpapers, one placed under the strand and one over is the:
double-flat wrap
Permanent wave rods are placed onto subsections of a panel called:
base sections
The position of a permanent wave rod in relation to its base section is the:
base placement
The technique of wrapping at a 90 degree angle or straight out from the center is:
half-off base placement
The two basic types of wrapping hair around a perm rod are the spiral method and:
croquignole method
A technique used to wrap extra-long hair using two rods in opposite directions is an:
piggyback wrap
A reduction reaction involves either the addition of hydrogen or removal of:
oxygen
A common, colorless reducing agent used in chemical texture servics is:
thioglycolic acid
The main reducing agent in alkaline permanents is:
ammonium thioglycolate
Most alkaline permanent waves have a pH between:
9.0 and 9.6
The primary low pH reducing agent in acid waves is:
glyceryl monothioglycolate
An exothermic chemical recation produces:
heat
The basic components of acid waves are permanent wave solution and:
activator and neutralizer
An endothermic wave must be activated using a:
outside heat source
In permanent waving, the processing should be determined by the:
strength of the solution
Hair that is too weak to hold a curl or may be completely straight after a perm is:
over-processed
The process of stopping the action of a permanent wave is:
neutralization
Permanent wave solution should be rinsed from the hair for a minimum of:
5 minutes
A 90 degree perm wrap that minimizes stress and tension on the hair is:
half off base
The process of rearranging extreamely curly hair into a straighter or smoother form is:
chemical hair relaxing
In extremely curly hair, the thinnest and weakest sections of the hair strand are located at the:
twists
Thio chemical relaxers usually have a pH value above:
10
The active ingredient in all hydroxide relaxers is the hydroxide:
ion
All hydroxide relaxers can swell the hair up to:
twice its normal diameter
Hydroxide relaxers remove one atom of sulfur from a disulfide bond converting it into a:
lanthionine bond
Disulfide bonds broken by hydroxide relaxers can never be:
re-formed
Hydroxide ions left in the hair after a relaxer can be neutralized using a:
acid-balanced shampoo
Relaxers containing one component used without any additional mixing are:
metal hydroxide relaxers
Sodium hydroxide relaxers (NaOH) are commonly called:
lye relaxers
A relaxer with two components mixed immediately prior to use is:
guanidine hydroxide relaxer
Lithium hydroxide relaxers and potassium hydroxide relaxers are advertised and sold as:
no-lye relaxers
Ammonium sulfite and ammonium bisulfite are marketed as:
mild alternative relaxers
Cream used to protect the skin and scalp during a hair-relaxing process is:
base cream
The strength of relaxers is determined by the concentration of:
hydroxide
To avoid overprocessing during a retouch relaxer application, wait until the last few minutes of processing to apply relaxer to the area:
closest to the scalp
Conditioners with an acidic pH that condition and normalize hair prior to shampooing are:
normalizing lotions
Curl re-formation does not straighten the hair, it simply makes the existing curl:
larger and looser
To avoid scalp irration, prior to the application of a hydroxide relaxer never:
shampoo the hair
To avoid excessive stretching of the hair when combing out tangles, use a:
wide-tooth comb
Performing texture services involves powerful chemicals that must be handled with:
caution
The term used to describe removing excess water before the application of a neutralizer is:
blotting
When checking for test curl development, the test curl should reflect:
firm S formation
When performing test curls, the rod should be unwound approximately:
1.5 turns
Incorrect placement of the rubber band of perm rods will cause band marks or:
breakage
When working with hair that has been chemically relaxed, you should avoid using:
hot irons
