Deck 1 Flashcards
What is the outer layer of the hair called?
Cuticle
Which part of the hair structure contains the temporary bonds that are effected by setting and blow drying?
Cortex
What are the bonds called that are changed during setting and blow drying?
Hydrogen and salt bonds
The change that happens to the hydrogen bonds is permanent. Is this true or false?
False. They are only broken down by moisture and gradually reset as the hair dries.
When would you use ‘on base’ setting method?
When wanting to create volume.
When would you use back combing?
To give structure and/or volume.
When would you use back brushing?
To create bulk. Mainly used when putting hair up.
What does hygroscopic mean?
Ability to absorb moisture.
What is the purpose of a styling product?
It puts a barrier on the hair shaft, preventing the hair from absorbing moisture which will then make the style last longer. It can also make the hair easier to control.
What is the purpose of a finishing product?
To help keep the style in. It also adds another barrier to the hair.
What is hair in its natural state called?
Alpha Keratin
When is hair in its natural state; wet or dry?
When wet
What is hair in its newly formed state called?
Beta Keratin
What is cohesive setting?
When setting the hair from wet to dry
Give an example of dry setting.
Tongs, wand, heated rollers. Any method where the hair is already dry.
How will very long hair affect the setting process?
The amount of product needed. Roller size and drying time.
What happens to the hair structure during the setting process?
The bonds are broken down and then reset in the new shape, going from alpha keratin to beta keratin.
Why must hair be kept damp when setting or blowdrying?
To prevent the bonds from re-setting and to keep the cuticle smooth.
When would a stylist use ‘Direction’ setting technique
To set the hair in the direction the hair is required to fall.
After removing rollers why is it important to brush the hair out thoroughly?
To remove any partings created by the rollers.
Why is it important to maintain even tension throughout the setting process?
To avoid an uneven curl.
Describe the effects of humidity on the hair structure.
It will change from beta keratin back to alpha keratin as the hydrogen and salt bonds will break.
What 3 things could you do to help hair in poor condition before and during blow drying?
Use conditioning treatment, heat protector and turn the heat down on the hair dryer.
What test is carried out to check the strength of the cortex?
Elasticity test.
