Colour Correction

Pre-Lightening

• Pre-Lightening is used to lighten areas of the hair. 
• Will remove natural and artificial pigment. 
•  Always follow manufactures guidance for pre-lightening
• A toner would then be used to deposit colour and neutralise tone.

Pre-Softening

• Hydrogen Peroxide is applied directly onto the resistant area of hair. 
• Allows the cuticle to open. 
•  Dry into the hair and apply colour. 
• Check manufactures instructions for what percentage to use. 

Colour Banding

• Bands of colour can appear due to uneven porosity, uneven application, poor colour matching.  
• Bands could be lighter or darker. 
• A colour reducer or lightener may be required to remove the banding. 
• You may be able to 'spot dye' lighter areas of banding. 

Neutralising Tone

• Use the colour wheel and colour chart to identify the opposing tones to  neutralise the unwanted tone.  
• Check with the manufactures instructions for the best product to use for neutralising. 

What are the primary colours in the colour wheel?

1. Orange, Blue, Violet
2. Yellow, Red, Green
3. Red, Yellow, Blue
4. Green, Yellow, Red

Correcting High/Lowlights

• Over lightened hair  may need to be correct by adding low lights to add depth back in. 
• Dull highlights may require re-lightening if the condition allows with a low developer.
• Product seepage can cause bleed marks due to incorrect placement/too much product in the foil. This will need to be corrected by spot dying the affected area to blend out the lines. 

Restore Depth & Tone

• This can be done using a semi-permanent or quasi colour to restore depth and tone to porous hair.
•  On some occasions a pre-pigment service may be required if they hair is very light to prevent the colour fading quickly.

Name some of the factors that can cause product seepage when foiling.

Pre-Pigmenting

• If the hair is light and the client wants to go darker the hair will need pigment re-added to it. 
• check with your manufactures instructions on which product is best to use. 
• always ensure you are pre-pigmenting in line with the end result for example if the client want a copper brown the pre-pigment colour needs to be copper.  

Colour Removers

• Colour reducers - removes artificial pigment by shrinking the molecules small enough to exit the cuticle. 
• Lighteners  - Mixed with oxidant or water to lighten the hair. Will remove artificial/natural pigment. 
• Always check the manufactures instructions. 
• Check the condition of the hair throughout the treatment. 

Factors that can cause colour to fade quickly.

Factors that could cause the colour to be too dark or too light.

Factors that could cause uneven coverage of white hair.
