Colour Correction

Slide 1 - Diapositive

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.

Slide 2 - Diapositive

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. 

Slide 3 - Diapositive

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. 

Slide 4 - Diapositive

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. 

Slide 5 - Diapositive

Slide 6 - Quiz

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. 

Slide 7 - Diapositive

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.

Slide 8 - Diapositive

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

Slide 9 - Question ouverte

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.  

Slide 10 - Diapositive

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. 

Slide 11 - Diapositive
