Colour Undo Before and After: How to use Colour Undo
Step Two
Saturate the mixture onto dry hair using a tint bowl and brush, making sure that the hair doesn’t dry out after application. Cover it with a plastic head cap. To protect your client’s face from the liquid, put a halo of cotton wool around the hairline. Leave the mixture to develop for up to 60 minutes or to your client’s desired result (this could be done within 10 minutes).
Step Three
Rinse your client’s hair thoroughly with warm water for 5 minutes and then apply approximately 25ml of the Buffer. Work to a lather and leave in the hair for 1 minute. Rinse once again with warm water for another 5 minutes.
Step Four
Apply a further 25ml of the Buffer and again work to a lather. Leave for 1 minute and then do a final rinse with warm water for 5 minutes. The Colour Undo process is then complete.
How Does Colour Undo Work?
Colour Undo works by reversing the hair colouring process. A permanent hair colour works by depositing small artificial pigment molecules inside the hair. When mixed and applied to the hair, Colour Undo shrinks the artificial colour molecules back to their original size. Once the hair has been rinsed and buffered, the shrunk molecules can be rinsed out from the hair without fear of re-oxidation, (the colour molecules re-expanding.) This will reveal the lightest, previous shade. This shade may be lighter than the natural hair colour, as bleach and ammonia from previous colour treatments may have lightened the natural pigment.
