The chemical action of ______ breaks the disulfide bonds and softens the hair Waving
Lotion
The chemical composition of the hair consist almost entirety of the protein material called
Keratin
Bonds that are formed between two cysteine amino acids located on neighboring polypeptide
chains disulfide
The Polypeptide chains of this layer of the hair are connected by end bonds and cross-liken by
side bonds that form the fibers and structure of hair in the Cortex
The perm that is activated by heat created chemically within the product is known as
exothermic
The action of waving lotion is to Expands the hair
The degree to which the hair absorbs the waving lotion is related to its Porosity
The length of time required for the hair strands to absorb the waving lotion and for the hair to
re-curl is called Processing time
The main active ingredient in acid-balance waving lotion is Glycerol Monothioglycolate
The main active ingredient or reducing AGENT IN ALKALINE PERM IS Ammonium
Thioglycolate
,The_____ wrap is used to prevent noticeable split and the flow of the hair Bricklay Perm
A wrap that is done at an angle that causes the hair to spiral along the length of the tool, like
the grip on the tennis racquet Spiral perm
The hydrogen atoms in the disulfide bonds are so strongly attracted to the oxygen in the
neutralizer that they release their bond with sulfur atoms and join with the ____ Oxygen
Under Processing is caused by_____ processing time of the waving lotion Insufficient
Waves that process more quickly and produce a firmer curls than true acid waves are
considered to be Acid-Balanced
What can be used to determine the actual processing time needed to achieve optimum curl
results when giving a perm for the first time on a client Preliminary test curl
A type of hair that is more fragile, easier to process, and more susceptible to damage FROM
PERM SERVICES Fine Texture
A type of hair that requires more processing than medium or fine hair and may also be more
resistant to processing Coarse Texture
When a strand of hair is wrapped at an 45 degrees beyond perpendicular to its base section, it
will result in on-base placement
When one end paper is folded in half over the hair ends like a envelope it is called the Book
end wraps
, When a strand of hair is wrapped at an 90 degrees perpendicular to its section, it will result in
half-off base placement
when performing a prem for a preliminary test curl, wrap one tool in each different area of the
head including the top,the side, and the____ Nape
When hair has assumed the desired shape, the broken disulfide bonds mush be _______
rebonded Chemically
When you place one end wrap on top of the hair strand and hold it flat Double flat wrap
A hair relaxing treatment should be avoided when an examination shows the presences of
scalp abrasions
After saturation the rods with the neutralizer in a soft curl permanent, the next step is to
Remove rods carefully
The physical and chemical process making the hair straight to curly is Perming
After the hair has been processed with a sodium hydroxide relaxer and before the shampoo,
the hair should be thoroughly Rinsed
Before giving a relaxing treatment to overly curly hair, the cosmetologist must judge its texture
, porosity and Elasticity and extent of damage, if any
If using a "no base" relaxer, it is recommended a protective cream be applied on the hairline
and around the ears
