Why is the colour wheel important when colouring hair?

The Colour Wheel

• We use the colour wheel as all depths of hair have underlying tone.

• The underlying tones are in the Eumelanin & Pheomelanin in the hair.

• Underlying tones can be exposed during colouring and lightening services.

• The colour wheel helps us identify what colours will naturalise unwanted tones.

Underlying Tones

Pheomelanin

Eumelanin

• Cool toned- Black /Brown colour pigments

• Harder to remove as the molecules are larger

• Warmer toned- Yellow, Orange and Red tones.

• Smaller molecules which are harder to remove.

The Effects of Colour on the Hair

• Large colour molecules which stain the cuticle.

• Does not penetrate into the cortex.

• Lasts 1-2 shampoos.

Semi-Permanent -

What effect does this colour have on the hair?

The Effects of Colour on the Hair

Semi-Permanent

• 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.

Permanent Colour -

What effect does this colour have on the hair?

The Effects of Colouring on the Hair

• 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.

• The molecules oxidise and swell to form large colour molecules.

Permanent

Lightener -

What effect does this colour have on the hair?

The Effects of Colour on The Hair

• Lightening the hair is a process of changing the natural colour pigments so they become colourless.

• The lightener penetrates the cortex and oxidises so that the pigment becomes colourless (Oxy-melanin)

Wella Colour Fresh Mask

Task - Application of Semi-Permanent Colour

• You will be working in pairs.

• Complete a client consultation - Identify your clients depth using the colour ring provided.

• Ensure your client is gowned up and you have your PPE ready.

• Colour Fresh Mask is applied to towel dried hair.

• Section the hair into manageable sections to ensure even coverage.

• Once applied comb through the mask to ensure even distribution.

• Leave for 10-20 minuets depending on intensity.

• Rinse thoroughly. No need to condition.

• Blow dry & style the hair.

The Effects of Colour on the Hair

• Mixed with a low volume peroxide.

• 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.
