Connect Activity

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)

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

Hair under a microscope

• The hair structure

Structure of the hair

The hair is made up of 3 main parts

• The Cuticle• The Cortex• The Medulla

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

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.

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

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)

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

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

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?

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?

Review of Learning
