B. Surface agents
C. Surfacants
C. Surfacants
A surfactant is an agent that actively ;

A. Reduces the surface tension
Complete the sentence. A surfactant molecule has a hydrophilic... A. Tail. B. Head C. Surface
B. Head
What does hydrophilic mean?

Oil loving
Complete the sentence. A surfactant has a lipophilic... A. Tail B. Head C. Body
A. Tail
A surfactant molecule dissolves in;
A. Water
B. Oil
C. Water and oil
C. Water and oil
True or false?
A surfactant molecule dissolves in both oil and water and joins them together, enabling the breakdown of oils within water.
True
True or false?
The lathering action of the ‘head’ and ‘tail’ of the surfactant creates a push and pull effect on the oil and grease, lifting it from the hair shaft.
True
The hydrophilic head of the surfactant is drawn to ;
A. Water
B. Oil
A. Water
The hydrophobic tail is drawn to ;
A. Water
B. Oil and grease on the hair and scalp.
B. Oil and grease on the hair and scalp
What is the lipophilic tail also known as?

Is our hair and skin acidic or alkaline?
Acidic
The natural pH of our hair and skin is;
A. pH 7
B. pH 10 - 14
C. pH 4.5 - 5.5
C. pH 4.5 - 5.5
True or false?
Shampoo and conditioner should be pH balanced to our hair and skin
True
pH 4.5 - 5.5. This ensures that the hair and skin’s natural moisture is maintained and the cuticle scales are closed.
Acid products have a pH0 - 6.9. Do they open or close the cuticle?
Close
Alkaline products have a pH7.1-14. Do they open or close the cuticle?
Open/ lift the cuticle scales.
What is the pH-neutral value?
pH7
What affect does strong Alkali have on hair?
It causes a depilatory action, destroying and dissolving the hair completely.
What is the word we use for a product that causes hair to dissolve completely?
Depilatory
What do we most commonly use alkaline products for?
We use them when we need to lift the cuticle scales so that chemicals can penetrate the cortex layer.
What pH are the shampoos used to cleanse and clarify the hair before a perm?
A. Acid
B. Neutral
C. Alkaline
B. Neutral
Acid products
A. Close or
B. Open/ lift
