Mix equal amounts of the Activator and Remover (approximately 50ml of each) using the measuring bottles provided in your pack.
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).
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.
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.
