Strand Testing

An image of wavy brown hair, representing the importance of a strand testPrior 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 Up

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.

Re-Colouring after Colourless

An image of 3 balloons, from pale pink to dark pink, representing picking a lighter colour when re-colouring the hair as hair is more porous and can go darker than intended 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.

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.

Reduction Agent ingredients work in the opposing principle to oxidation, which is the technology from which permanent colouring works. A notable factor about Reduction Agents is they have a sulphur smell, which can often be likened to eggs. Particularly dry or porous hair is more likely to hold on to these chemicals longer so will require several if not more shampoos. The remover must be rinsed with hot (comfortable) water; otherwise, there is a chance the odour could cling to the hair for several days after the removal treatment.

Wash the hair with a clear, clarifying shampoo under hot (comfortable) water. Next, dissolve two teaspoons of bicarbonate of soda into a mug of hot water. Wait for the mug to cool, then rinse the bicarbonate of soda solution through the hair and leave for 10 minutes before flushing the hair with warm water. Finish with a leave-in conditioning treatment. The bicarbonate of soda rinse will neutralise any odour left in the hair. If you still detect some of the smell, you can repeat the process.

As an over & above measure, you can use a hair mask. Chose a beautiful smell that you like (you can also add your favourite essential oil scent to the hair mask), leave it on the hair for 10-15 minutes, and then rinse.

When not to use Colourless

A strand test should be completed before attempting a full head treatment.

Do not use Colourless if you have Henna or natural plant based colour in your hair.

Undertones & how to neutralise them

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.
