Colouring lesson 6
Slide 1 - Slide
Today's session
Recap the depths and tones used with Wella
Recall the molecules found in hair colour and how this effects the hair structure.
Describe the different hydrogen peroxides and the effect each one has on the hair.
Identify some problems that could occur when colouring hair and their remedies.
Slide 2 - Slide
Keyterms
Oxidisation
Oxy Melanin

Slide 5 - Slide
Undertones
This is because the pheomelanin pigments are smaller and harder to remove. You need to understand what the natural shade has underneath to make it that depth.
When you are removing colour you will be lifting colour – both natural and artificial – out of the hair.

Temporary colour
Slide 17 - Drag question
Temporary colour

Does not penetrate into the cortex.
Lasts 1-2 shampoos.

Slide 25 - Open question
07:55
What are the 2 types of melanin?
Slide 26 - Open question
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.
Slide 27 - Slide
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.
Slide 28 - Slide
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 colourless molecules penetrate through the cuticle and into the cortex.
Oxidisation - A chemical process which combines a chemical with oxygen.

Case study 2
Permanent colour as long as the hair is virgin.
6% / 20 vol needed for 1 level of lift.
If the hair is coloured, you would need to pre-lighten.

Case study 3
The ends need to be re coloured if the condition allows – then use a ashy toner on the hair with a low level peroxide.
If the condition wont allow – the client needs to be taken down to the base of an 8 or lower and use an ashy quasi colour.
This client has just had all her hair lightened. Her roots are a base of a 10 and the mid-lengths are an 8. She wants to be more of an ashy blonde. What would you do?
