GH11 & GH10 revision L2

What will happen when you wet set the hair?

• Change the hydrogen bonds back to their natural state called Aplha - keratin

• Break down the hydrogen bonds and re form them into a new shape called beta-keratin

• Allow the moisture to penetrate the cuticle

• Allow the use of styling products to de crease the moisture

Why do we allow the hair to cool prior to dressing out

• Stops the hair from becoming dry and brittle

• allows the hydrogen bonds to soften

• Allows the hydrogen bonds to harden

• Stop you from getting body and height into the hair

What effect does humidity have on the hair?

• returns hair to its natural shape

• Keeps the shape of the hair

• Makes it shine

• Makes it stand up

What can happen if you have excess heat on the hair?

• Psoriasis

• Folliculitis

• Tinea capitis

• Fragilitis crinum

Excess heat on the scalp can cause

• Dandruff

• Alopecia

• Burning

• Brusing

Heated styling products protect the hair by

• Protecting the cortex

• Protecting the medulla

• Puts a protective film on the cuticle

• Protects the skin

Keeping the hair damp during the setting process wil

• make the cuticle scales smooth and flat

• ensure the hair takes on the shape of the set

• ensure the layout of the rollers is effective

• leave hair free of sectioning marks

When using heated styling processes on dry hair, which bonds are re-formed?

• Hydrogen

• Disulphide

• Polypeptide

• Sulphur

Why should hair be kept damp during the blow-drying/finger-drying process? To

• allow styling products to be diluted

• allow a new shape to be created

• keep the medulla smooth

• keep the cortex smooth

What physical effect does blow-drying have on the hair?

• re-forms the polypeptide chains

• changes it from beta-keratin to alpha-keratin

• changes it from alpha-keratin to beta-keratin

• breaks down the polypeptide chains
