Unit 003
Task A

2. Connect Activity
To previous unit 102
Fruit Machine or words

3. Aims and Outcomes
Introduce the learners to the hair structure, the main hair conditions and what shampoo does to the hair and scalp.
Learners outcomes
Illustrate understanding by creating a model of the hair structure (LO3)
Identify the main hair conditions (LO1)
Explain what shampoo does to the hair and scalp (LO2)
Describe what conditioner does to the hair and scalp (LO1)

4. Structure of the Hair Think of each hair as being like a pencil
The paint on the outside
The wood is the main part
The lead that runs through the middle

5. Hair under a microscope
The hair structure

6. Structure of the hair The hair is made up of 3 main parts The Cuticle
The Cortex
The Medulla

7. The Cuticle This is the outer layer of the hair
Cuticle scales are like roof slates or
fish scales
They overlap down the hair shaft
They are translucent so you can see
the hair colour underneath them
Hair in good condition has very tightly closed cuticles
Hair in bad condition has open, damaged cuticles

8. The Cortex This is the inner part of the hair
This is where any changes to the hair take place
If we blow dry or straighten hair it is this part that changes
If we colour or perm our hair it is this part that changes
We can damage the cortex if we use harsh chemicals
If the cortex is damaged the hair will have high elasticity (stretch and snap)
Try stretching your hair to determine if it damaged.

9. The Medulla This is the central layer of the hair
It is simply made up of air spaces
It has no real purpose
It is not always present in fine hair

10. Main Hair Conditions Normal (no problems, fruit based)
Greasy (a lot of natural sebum is produced, lemon)
Dry (not enough natural sebum is produced, oil)
Chemically Damaged (over use of harsh chemicals, protein)

11. What Does Shampoo do to the Hair & Scalp?
Shampoo contains detergent molecules
Shampoo mixes easily with water
This allows the grease and dirt to be caught up in the lather and rinsed away
Shampoo cleans the hair & scalp getting it ready for the next service

12. What Does Conditioner do to the Hair?
Surface conditioners
Coat the hair shaft
smooth down the cuticle
Penetrating Treatment Conditioners
Strengthen the cortex
Replace moisture

13. The Hair Shaft Task
Create a model of the hair shaft using the materials provided. Brief description of the three main parts.
Plan
Remember your pencil?

14. Recall Name the outer layer of the hair?
Name the inner layer of the hair?
Name the innermost part of the hair?
Is the cuticle see through?
Name 1 type of chemical damage?
Name 1 piece of electrical equipment that may damage the hair?
Describe what the cuticle looks like?
If the cuticle is smooth and closed would you expect the hair to be healthy?
Why would you think of a pencil?
Can you predict which part of the hair will become damaged with bleach?
Can you see through the cuticle?

15. Review of Learning
On the wipe board write down three key words you have learned
Or three things you have learned
