Prior to using Colourless, even if you have used it before, we recommend doing a strand test. This is the only fail safe way to understand what your end result and condition of your hair will be.
Mix 5mls of Bottle A with 5mls of Bottle B in a separate plastic or glass container. Do not use metal.
Apply to a small section of your hair, saturating it from root to tip (or whatever area of colour your are wanting to remove).
Wrap in cling film, and process for 60 mins. Rinse thoroughly.
The colour and the condition of this section of hair will dictate your end result.
If you are not happy with the result, do not proceed with the full head application, as it will not be any different.
Colour build is common when you colour at home, and take the colour from roots to tips with every application (vs. application to the roots and taking to the ends in the last 10 minutes). The easiest way to tell if you have colour build up is if your ends are (unintentionally) darker than the roots. Using Colourless Hair Colour Remover prior to every third application of your hair colour is the best way to prevent build up, giving you an even base for optimum results.
After an application of Colourless, it is common for your hair to become more porous. This means that your hair will absorb the colour pigment more readily during your next application, which in turn can lead to a darker result than may be desired.
To prevent this, it is recommended to go 2-3 shade lighter than your intended end result. i.e. if you want a dark brown end result, purchase the lighter brown shade.
The most common mistake that is made when using Colourless, is not setting a timer for the rinsing stage. This can result in some of the artificial colour pigments remaining in your hair shafts, and they may re-oxidise. Your hair could then return to the colour that you are trying to remove.
You cannot over rinse, but you can under rinse. If you have thick and/or long hair, ensure you rinse for longer at each stage of the process.
When you are using Colourless Hair Colour Remover, you are removing the artificial colour pigments that you have previously put in your hair. Every time you colour your hair, you alter the natural undertone of the hair, which starts at red for dark hair, and goes through all the shades of orange up to yellow, as the hair gets lighter.
If you are not wanting warm tones in your next colour, you will need to neutralise these undertones to counteract them. Blue/Ash will neutralise Orange, and Purple/Violet will neutralise Yellow.
