Session Aim- Consultation Principles 

The principles of hair and skin structures 

Objectives:

Be able to recall keywords about the hair structure- Collaboration Task  

Be able to recall the different characteristics and Classifications 

Introduction to the skin Structure and Hair growth cycle of hair

Recall the main aspects from today's session in relation to the Hair growth stages and the skin structure. 

In pairs, can you recall Ten different aspects of the hair structure

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. 

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.  

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. 

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.

Can you list the Hair Classifications?

What are some possible causes of damaged hair?

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

Hair Classifications 

Type 1- Straight Hair

Type 2- Wavy Hair

Type 3- Curly Hair

Type 4- Very Curly Hair 

Hair Classifications 

Type 1- Straight Hair

Type 2- Wavy Hair

Type 3- Curly Hair

Type 4- Very Curly Hair
