Style dress and finish Revision Quiz

What are the polypeptide chains made of within the cortex?

• Keratin

• Oxygen

• Carbon

• Hydrogen

What are the chemical compound combinations that make up the polypeptide chains?

• Carbon, Hydrogen, Oxygen, Sulphur and Nitrogen

• Carbon, Hydraulics, Oxford, Sulphate and Nitrous

1 What does humidity in the air mean?

• Water (moisture) in the air

• Heat in the air

How does Humidity affect the hairstyle?

• Hair will be formed into it's new state of beta keratin.

• Hair has the ability to absorb moisture in a very humid environment, this would attack a hairstyle. Once moisture is in the hair will go from beta keratin, reverting the hair back to alpha keratin.

Can you explain why it is important to allow hair to cool before you brush the hair out and finishing it?

• This allows the hair to form into its new shape of alpha keratin.

• This allows the hydrogen bonds to fix into their new state of beta keratin

  It will also allow the style to last longer.

Describe wet setting?

• Shampoo the hair to ensure it reverts back to it’s original state (alpha keratin) as the hydrogen bonds will break when water enters the cortex

  During the setting or blow-drying process hair is changed to beta keratin and will stay this way until it is shampooed again or until attacked by moisture from a humid environment. This will last longer and give a tighter curl.

• Shampoo the hair to ensure it reverts back to it’s original state (beta keratin) as the bail bonds will break when water enters the cortex

  During the setting or blow-drying process hair is changed to Alpha keratin and will stay this way until it is shampooed again or until attacked by moisture from a humid environment.

Describe dry setting?

• You would not shampoo hair before a dry set and the bonds are not as easily broken.

  This will last longer and give a tighter curl.

• You would not shampoo hair before a dry set and the bonds are not as easily broken.

  By applying styling products in conjunction with heat, a few bonds will be broken and give a much softer curl.

Can you describe the physical changes that take place during the setting/blow-drying process and name the two bonds that are involved?

• Alpha keratin is when hair is in it’s natural shape Beta keratin is when hair has been set or blow-dried into a new shape Hair will remain in beta keratin until it is washed or moisture from the air attacks the hair then it will then return to Alpha keratin

• Beta keratin is when hair is in it’s natural shape Alpha keratin is when hair has been set or blow-dried into a new shape Hair will remain in beta keratin until it is washed or moisture from the air attacks the hair then it will then return to Beta keratin

Which 3 styling products put a coating on the hair to prevent moisture from the air entering the cuticle and reverting the hair back to it's original state (alpha-keratin).

• Gel, Wax and shine spray.

• Setting/styling lotion, mousse and spray

What must you always follow when using professional products.

• Always follow manufacturers instructions.

• Always follow salon protocol.
