Chemical Relaxer Flashcards
Long, coiled polypeptide chains
Keratin proteins
Compound made up of carbon, oxygen, hydrogen nitrogen, and sulfur
Amino acid
Tough exterior layer of the hair
Cuticle
Hair that is treated with hydroxide relaxers must not be treated with
thio relaxers
Chemical services should not be performed if the scalp analysis shows any signs of:
abrasions
A combination of a thio relaxer and a thio permanent wrapped on large rods is a:
soft curl permanent
Conditioner with an acidic pH that restores the hair’s natural pH after a hydroxide relaxer is:
normalizing lotion
The application for chemical relaxers should be started in the most resistant area, usually the:
back of head
During a relaxer strand test, hair that is pressed to the scalp and continues to curl is:
insufficiently relaxed
The difference in the strength of most chemical hair relaxers is determined by the concentration of:
hydroxide
Hydroxide relaxers that do not require the application of a protective base are:
no-base relaxers
Relaxers that contain two components and must be mixed immediately prior to use are:
guanidine hydroxide relaxers
Relaxers are often marketed and sold as no mix–no lye relaxers are:
potassium hydroxide relaxers
Sodium hydroxide relaxers are commonly called:
lye relaxers
Relaxers that contain only one component and are used without mixing are:
metal hydroxide relaxers
Hydroxide relaxers remove a sulfur atom from a disulfide bond, converting it into a(n):
lanthionine bond
The active ingredient in all hydroxide relaxers is the:
hydrogen ion
The process of rearranging the basic structure of curly hair into a straighter or smoother form is:
chemical hair relaxing
The cortex layer of the hair structure is responsible for the hair’s
strength and elasticity
The term pH is an abbreviation used for
potential hydrogen
The wrap uses one end paper folded in half over the hair ends like an envelope.
The bookend wrap
Japanese thermal straightening combines use of a thio relaxer with
flat ironing
What straightening treatments work by fixing the keratin in place in a semipermanent manner; they do not break bonds.
Keratin
The process of chemically altering the natural wave pattern of hair is:
chemical texture services
The range of numbers used in the pH scale is:
0 to 14
The active ingredient in all hydroxide relaxers is the
hydrogen ion
Hydroxide relaxers that do not require the application of a protective base are:
no-base relaxers
The application for chemical relaxers should be started in the most resistant area, usually the:
back of head
Most common type of perm rod
Concave rod
Also known as the circle rod
Loop rod
Permanent waves that have a 7.0 or neutral pH
Acid-balanced waves
Hair is wrapped at an angle other than perpendicular to the length of the rod
Spiral perm wrap
Also known as a straight set wrap
Basic permanent wrap
Chemical services should not be performed if the scalp analysis shows any signs of _____.
abrasions
Hair that has been treated with a hydroxide relaxer is unfit for _____ and will not hold a curl.
permanent waving
_____, often found in home haircoloring products, leave a coating on the hair that may cause uneven curls, severe discoloration, or hair breakage.
