Does the hair need to be pre-lightened before colouring with Bold colours and/or Pasteliser?
To ensure vibrant, colourful results, if you have darker hair, we would recommend you to pre-lighten your hair to a light blonde with the Lightener Kit. The Bold Colours can be used on hair which has not been pre-lightened but results would not be vibrant unless you have naturally light, bright blonde hair.
Leaving the colour on the hair for 40 minutes and pre-treating with Hydrate Treatment will help achieve the best results. Pastel Colours would also be difficult to achieve unless the hair is pre-lightened or applied to naturally light bright blonde hair.
