00
second
Definition of: Alpha Keratin
Alpha Keratin
Hair in its natural state
Definition of: Beta Keratin
Beta Keratin
Hair when it has been styled into a different shape either by drying or use of heated styling equipment
Definition of: Hygroscopic
Hygroscopic
The ability to absorb moisture from the atmosphere.
Definition of: Salt Bonds
Salt Bonds
Temporary bonds which are softened by changes in the pH level of the hair and are reformed when the pH level returns to normal. Found in the cortex
Definition of: Hydrogen Bonds
Hydrogen Bonds
Temporary bonds which are broken down by water or heat, and are reformed during either the drying and cooling process or use of heated styling equipment. Found in the cortex
Definition of: Di-sulphide Bonds
Di-sulphide Bonds
Permanent bonds and can only be broken down during a chemical service, like during the perming process. Found in the cortex.
Definition of: Polypeptide Chain
Polypeptide Chain
Chains found in the cortex of the hair. Made of amino acids and peptide bonds. Held together by temporary and permanent bonds
How does humidity effect the hair?
Humidity and the hair
Hair is hygroscopic, meaning it has the ability to absorb moisture from the atmosphere.
When we go out in a humid environment, your hair will absorb the moisture, softening the hydrogen bonds and reverting from beta keratin (its changed shape) back to its alpha keratin (natural state)
Describe the physical effects of styling on the hair. Remember to use key terms!!!!!!!!!!!!
Physical effects of styling
Shampooing the hair breaks the hydrogen and salt bonds. These are temporary bonds which are found within the cortex.
When you dry the hair, these bonds are reformed into a new, temporary shape. This is known as hair in its beta keratin state. When the hair is shampooed again it returns to its natural alpha keratin state.
