Unit 203- Advise and Consult 

Today's Session 

Consultation Principles 

Recall Hair Growth patterns 

Recall the hair structure 

Be able to define the difference between Characteristics and Classifications 

Introduction to the Skin Structure 

Can you recall the different Hair Growth Patterns

Double Crown: A standard hair crown is a circle of hair that grows around a visible centre point on the head in a clockwise direction. However, a double crown describes two small, circular areas of baldness on your head.

Cows Lick: A cowlick is a section of human hair that stands straight up or lies at an angle at odds with the style in which the rest of an individual's hair is worn. 

 Nape whorl: a specific pattern of growth in which a section of the hair grows in a spiral or curved shape at the nape of the neck

Widows peak: A widow's peak is a V-shaped point in the hairline in the centre of the forehead. Hair growth on the forehead

1. A V-shaped point in the hairline on the forehead
2. A specific pattern of growth at the nape of the neck

I see....... 

What do you see in this picture? Discuss...

Can you recall the three layers of the hair structure and state two facts for each layer?

Cuticle 

• Is made up of transparent overlapping scales 
• Heat/ chemicals will open the cuticles 
• The cuticle scales should ideally be closed from root to tip to give the hair shine and lustre 
• Healthy hair reflects light 
• Damaged cuticle scales will make the hair feel porous and appear dull
• When the hair is in good condition they are water repellent and when in poor condition they will allow more water to be absorbed into the hair making it more porous. 

What happens when the cuticle scales are damaged?

1. Hair loses color
2. Hair feels porous and appears dull
3. Hair grows faster
4. Hair becomes thicker

What can open the cuticles?

1. Water
2. Sunlight
3. Heat/chemicals
4. Brushing

What is the cuticle made up of?

1. Transparent overlapping scales
2. Sebaceous glands
3. Protein fibers
4. Melanin pigment

Cortex 

• This is the section under the cuticle and is where most the action happens.  
• Your natural colour is determined in the cortex and this is where artificial colouring mostly takes place.
• It is this layer that has the bonds which hold your hair in place to determine if your hair is straight, wavy, curly or very curly. 
• Where the hair is temporarily or chemically changed from straight to curly or curly to straight. 
• It is the main part of the hair that gives it's strength and elasticity.  

Which part of the hair is responsible for its strength and elasticity?

1. Cuticle
2. Epidermis
3. Medulla
4. Cortex

Which layer of the hair holds the bonds to determine its texture?

1. Epidermis
2. Medulla
3. Cortex
4. Cuticle

Which layer of the hair is responsible for determining your natural color?

1. Medulla
2. Epidermis
3. Cuticle
4. Cortex

Medulla  

• The medulla is the least interesting layer. 
• it is the central part of the hair but is not always present. 
•  In a single strand it may fade in and out when analysed under a microscope  or it may be present all the way through in some hair types.
• it tends to appear in more thicker or coarser hair textures. 

In which hair types is the medulla more likely to be present all the way through?

1. Blonde or brunette hair types
2. Thicker or coarser hair types
3. Curly or wavy hair types
4. Thin or fine hair types

 Keywords Task-  Write a paragraph using as many keywords as possible. Remember to check spellings... 

Once completed swap your work with a peer and get them to check if they can add or amend any aspects.

List as many Keywords you can think that relate to ' Characteristics and Classifications '

Is the medulla always present in every strand of hair?

1. No
2. Sometimes
3. Yes
4. It depends on the hair type

Can you list the Hair characteristics?

Hair Characteristics 

Hair Density 

Hair Texture 

Hair Growth Patterns 

Elasticity 

Porosity 

Hair Condition 

Straight Hair 

Charateristic 

Classification 

Porosity 

Elasticity 

Hair Growth Patterns 

Hair Texture 

Hair Condition 

Curly 

Wavy Hair 

Hair Density 

Very Curly Hair 

Hair Density 

Hair density refers to the amount of hair and is described as Sparse, Average ( Medium)  or Abundant.

• Sparse hair often means the hair is fine and there is not a lot of it covering the head. The scalp may be visible through the hair, less product will be required and the types of hairstyles that will suit this density will need to be considered.
  
• Abundant hair means the client has a full head of hair, this may be fine or coarse in texture
• Abundant hair requires more product more drying time, it will take longer for services to be carried out.
• Sparse hair- Cutting techniques will need to be considered as the hair may need to be thinned out.
  

What does hair density refer to?

1. The texture of hair
2. The length of hair
3. The color of hair
4. The amount of hair

Hair Texture 

Hair texture refers to the thickness of each strand of hair and is described as

Fine, Medium or Coarse.

• Fine hair has a small circumferences and fewer layers of cuticle scales.
  
• Medium hair is greater in circumferences than fine hair with an average numbers of layers.
  
• Coarse hair a large circumference and the most layers of cuticle scales.
  
• Fine hair will absorb chemicals much faster than coarse hair because there are fewer cuticle scales. 
• Coarse hair can often be resistant to chemicals.
  
• A porosity test can be carried out on all textures to check whether these cuticle scales are rough and open, or smooth and closed.
  

Which hair texture has the most layers of cuticle scales?

1. Medium
2. Fine
3. Coarse

Hair Elasticity 

Refers to how weak or strong the hair is and whether the cortex layer has been damaged.

You will need to consider if the hair is strong enough to take additional chemicals or whether to advise another product i.e. colour or styling products.

Consider how much tension is applied.

Why is hair elasticity important when considering additional chemicals?

1. To determine if the hair is strong enough
2. To enhance the color of the hair
3. To prevent hair breakage
4. To create unique hairstyles

Hair Condition 

Normal, dry, oily or damaged ( by chemicals or environmental, heat or lifestyle).

Identify how it has been damaged, advise client on how to prevent further damage and improve the condition.

Damaged hair is likely to have poor elasticity and or porosity.

Consider if a chemical treatment should be carried out.

What are some possible causes of damaged hair?

1. Environmental factors
2. Heat
3. Lifestyle
4. Chemicals

Can you list the Hair Classifications?

Hair Classifications 

Type 1- Straight Hair

Type 2- Wavy Hair

Type 3- Curly Hair

Type 4- Very Curly Hair 

What do you already know about the structure of the skin?

Epidermis 

Dermis 

Subcutaneous Tissue 

Muscle 

Sweat Gland 

Hair 

Sebaceous Gland 

Sensory Nerve Ending 

Nerve 

Explain the difference between the Epidermis skin and the Dermis

The skin is made up of how many layers?
