Lesson Objectives:
By the end of the session learners will be able to:
Recall key knowledge from the previous lesson, including the Colour wheel, lightening curve, colour pigments and melanin types.
Explain the difference between eumelanin and pheomelanin and identify the tones they produce in hair.
Identify the different types of colouring products (temporary, semi-permanent, quasi-permanent and permanent) and describe how they affect the hair structure and colour molecules.
Describe the role of hydrogen peroxide developers and explain how different strengths affect the colouring and lightening process.
Apply product knowledge to salon scenarios, including selecting the correct developer strength and mixing ratios for grey coverage and controlled lightening.

Slide text
Eumelanin
Cool toned- Black /Brown colour pigments
Harder to remove as the molecules are larger
Pheomelanin
Warmer toned- Yellow, Orange and Red tones.
Smaller molecules which are harder to remove.

Describe the difference between Eumelanin and Pheomelanin
Types of colouring products
How different colouring products effect the hair structure
For each colouring product, you need to be able to identify the following about each colouring product:
What size colour molecules are found in the product?
How does the colour effect the hair structure?
Temporary Colour
Large colour molecules which stain the cuticle.
Does not penetrate into the cortex.
Lasts 1-2 shampoos.
Semi Permanent colour
Large and small colour molecules.
Small colour molecules are deposited into the hair cuticle and outer edge of the hair cortex.
Colour will last 6-8 washes.
If the hair is unevenly porous, the result may be patchy.
Quasi permanent colour
Mixed with a low volume peroxide (1:2 ratio).
Small and medium colour molecules enter the cortex and oxidise by the oxidant (peroxide)
Due to low peroxide, the colour molecules do not become very large and are gradually lost each time the hair is shampooed.
Lasts around 12 weeks.
Colour Touch
Used for:
Full head applications of colour
Grey blending
Colour Balancing
Transformational Toning
Permanent colour
Mixed with hydrogen peroxide.
The strength of the peroxide used varies depending on the desired result. Normally 4%, 6%, 9%, 12%.
When mixed with peroxide the small molecules penetrate through the cuticle and into the cortex.
Koleston Perfect
Used for:
Full head applications
Regrowth applications
100% white coverage
Achieve up to 3 levels of lift on virgin hair.
Lightener
What colour pigments does eumelanin produce?
Warm toned yellow/orange/red colours
Cool toned black/brown colours
How long does temporary colour last?
1-2 shampoos
6-8 washes
What size molecules are in semi-permanent colour?
Only large colour molecules
Large and small colour molecules
What is a characteristic of quasi-permanent colour?
Mixed with low volume peroxide
Contains only large molecules
What does permanent colour mix with?
Hydrogen peroxide
Water
Hydrogen Peroxide
Also know and written as H202.
This is a colourless liquid made from...
Water
Oxygen

Slide heading
Stronger peroxide does not mean a better blonde result. The aim is controlled, even lift while protecting the condition of the hair.
When using lightener, the approach is “slow and low.” This means choosing a lower strength developer, such as 1.9% or 4%, and allowing it to process for longer.
This helps you:
Lift the hair more evenly
Reduce damage
Maintain better hair health
Stay in control of the lightening process
Remember: it’s not about lifting as fast as possible — it’s about lifting safely and professionally.
How would you achieve 100% coverage of white hair?
Task:
Write a mixing Ratio using 5/0 and 5/5 to achieve both 30-50% coverage and 50-100% coverage.
