The process of permanently rearranging the basic structure of overly curly hair into a straight form is
called:
chemical hair relaxing
Of the general types of hair relaxers, which one does not require pre-shampooing?
sodium hydroxide
The chemical required to stop the action of the chemical relaxer is:
neutralizer
The processing time of a chemical relaxer is affected by:
the hair's porosity
What stops the action of any chemical relaxer?
neutralizer
Hydroxide relaxers are usually sold in ______________ formulas
base and no base
What are the three basic steps used in chemical hair relaxing?
processing, neutralizing, conditioning
The strength of relaxer is determined by the strand test. General guidelines suggest that for fine, tinted, or lightened hair, the following strength is used:
mild
The strength of relaxer is determined by the strand test. General guidelines suggest that for coarse virgin hair, the following strength is used:
strong or super
Before giving a relaxing treatment to overly curly hair, the cosmetologist must judge its texture, porosity and:
elasticity and extent of damage, if any
The action of a sodium hydroxide relaxer causes the hair to:
soften and swell
The process of breaking the hair's disulfide bonds during processing and converting them to lanthionine bonds when the relaxer is rinsed from the hair is known as:
lanthionization
The scalp and skin are protected from possible burns when using a hair relaxer by applying:
base cream
After the hair has been processed with a sodium hydroxide relaxer and before the shampoo, the hair should be thoroughly:
rinsed
The relaxer cream is applied near the scalp last because processing is accelerated in this area by:
body heat
If using a "no base" relaxer, a protective cream may be applied:
to the hairline and around the ears
The best type of shampoo to use after the chemical relaxer is:
a neutralizing shampoo
When applying sodium hydroxide relaxer, the processing cream is applied last to the ______________ and ______________.

When using the comb method of application, how is the relaxing cream applied?
with the back of the comb

To check relaxer processing, smooth and press a strand to the scalp using the back of the comb or your finger. If the curl returns, ______________.
continue processing
The combination of a thio relaxer and a thio permanent wrapped on large tools is called a:
soft curl permanent
What is one safety precaution that must be followed with all chemical hair relaxing services?
wearing protective gloves
One safety precaution for hair relaxing is to avoid ______________ the scalp with the comb or fingernails.
scratching
After saturating the rods with neutralizer in a soft curl permanent and processing according to directions, the next step is to:
remove rods carefully
Relaxers which are ionic compounds formed by a metal combined with oxygen and hydrogen are known as:
metal hydroxide relaxers
Sodium hydroxide relaxers are commonly called
lye relaxers
When processing is complete for a soft curl permanent, what is done after rinsing the hair thoroughly with warm water?
each curl is blotted with towel
What is used to restore the hair and scalp to their normal acidic pH?
normalizing lotion
