Perm/Wave/Chem Review Flashcards
This is a tough exterior of the hair
Cuticle
Removing curl, leaving the hair smooth and wave free is known as
Relaxing
These are the most common types of perm Rod, with a smaller diameter in the center than the end
Concave rods
Absorbent paper is used to control the ends of the hair when wrapping and winding hair on Perm rods
End papers
Position of the rod in relation to its base section
Bass placement
These types of bonds or we can can’t be broken by water or heat
Hydrogen bonds
Wrapping from the ends of the scalp in overlapping concentric layers
Croquignole perm wrap
Loosening overly curly hair, such as wind tight curls are turned into loose curls or wave
Curl reforming
The middle layer of the hair located directly beneath the cuticle layer
Cortex
When the hair is wrapped 45° above the center
On-base
When the hair is wrapped at an angle of 90°
Half-off base placement
When the hair is 45° below the center
Off-base placement
A colorless liquid with the strong, unpleasant odor, it is the most common reducing agent in the permanent wave solutions
Thioglycolic acid
These are known as cold waves, and have a pH between 9.0-9.6. They process at room temperature without the additional ofheat
Alkaline waves
Does type of chemical reaction produces its own heat
Exothermic
This type of chemical reaction is one that absorbs heat from its surroundings, such as hooded dryer
Endothermic
Broken hair may result from the wrapping of the hair with too much
Tension
Normal elasticity is classified as being able to stretch wet hair up to___% of its original length
50
When the hair is wrapped to an angle other then perpendicular to its length of the tool, it is a technique called
Spiral wrapping
This type of wrap is one which one and paper is placed under and another is placed over the strand of hair being wrapped
Double-flat
This type of wrap uses one and paper folded in half over the hair and like an envelope
Bookend
These types of brides are equal in diameter all along the entire length of curling area
Straight rods
You should rinse your perm solution for at least
Five minutes
After processing and rinsing the perm solution from the hair you should
Towel blot the rods
This type of wrapping technique has space sections are offset one another row by row to prevent noticeable split in the blend the flow of the hair
Bricklay perm wrap
This technique uses zigzag partings to the divide base areas
Weave technique
During a virgin relaxer, relaxer should not be applied until the last few minutes of processing:
To the scalp and ends
Do not shampoo the hair prior to the application of a
Sodium hydroxide relaxers
After relaxer has been rinsed from the hair, you may apply normalizing solution and leave it for about
Five minutes
Hair texture is classified as
Coarse medium and fine
And oily cream used to protect the skin and scalp during hair relaxing is known as
Base cream
This type of permit app is used for extra long hair, and the hair is wrapped on one rod from the scalp to midway down the hair shaft
Piggyback wrap
Do not perm hair that is____________or shows signs of breakage
Damaged
Always apply protective barrier________ around The clients hairline and years prior to applying permanent waving solution
Cream
Always follow_____________ __________ when applying perm solution
Manufactures direction
Immediately replace cotton or towels I have become wet with
Perm solution
A successful person takes time, patience and expertise. Proper ________ and _______ are important
Rinsing, blotting
Do not apply thio relaxeror soft curls perm on here that has previously been treated with a __________ _________ relaxer
Sodium hydroxide
Apply protective _______ _______ to avoid scalp irritation during the sodium hydroxide relaxers
Base cream
Sodium hydroxide relaxers are used for_________ ___________ or ethnic hair
Overly curly
Straight paragraph is sectioned into ___ sections for control
Nine
The size of your party is in your section are determined by the_______of the rod
Diameter
The most important factors to consider it a hair analysis for chemical texture services include ___________ and_______
Elasticity and texture
In order for the hair to hold the curl in racist damaged during a chemical texture surveys, the hair must have good __________
Elasticity
Applying leaving solution and neutralizer during a perm causes a _______ change in the hair strand
Chemical
The correct processing time for optimal curl development can be determined by doing a ____________________ _______ _______
Preliminary test curl
To properly process the resistant hair when permanent waving, it’s particularly important to ___________ it thoroughly
Saturate
Permanent waving is known as
Adding wave or curl to the hair
