There are many reasons why we can decide we do not want an artificial permanent hair colour shade. These can include (but are not limited to):

A colour mistake

You have applied a permanent colour, and it has not resulted in the shade you had hoped. Perhaps it is too dark, too tonal or doesn’t suit you. The fact is, you now wish that colour result to be gone.

Wishing to go lighter

Maybe you have been colouring a natural lighter base to a darker or redder shade, and you now want to remove those artificial colour pigments and go lighter.

You have noticed colour build-up

Colour build-up occurs after artificial permanent colour is continually applied throughout the hair with every regrowth application.
Over time, that artificial colour becomes built-up inside the hair, causing the shade to turn darker and darker, especially on the mid-lengths and ends.

In all the above scenarios, the best solution to achieve the result you want is to apply Decolour Remover.

Decolour Remover is a three-part hair colour removal system designed for use in the home. It’s quick, simple and effective to use and works only on artificial oxidation (permanent) colour molecules. Meaning, the product will remove unwanted hair colour, without effecting or lightening the underlying natural hair colour.

How does it work?

Decolour Remover uses a technology known as ‘reduction’.
Bottles Part 1 and Part 2 are intermixed, and the formula is activated and applied to the hair. The reduction agent ingredient then enters the cortex (the hair’s central area), locates the synthetic colour pigments, shrinks and shatters them. Those unwanted colour molecules can then be flushed from the hair during the rinsing phase. At the rinsing stage the hair remains in an open state, and here the Part 3 Conclude Balm is applied. The Conclude Balm formula features plant proteins which enter inside the hair, filling any gaps and moisturising the central area, before closing and protecting the cuticle. Results are a removed colour, with hydrated and re-conditioned hair fibres.

With Decolour Remover, you do not always need to conduct a whole head traditional application. It is possible to work with the product to create specific results based on your colour requirements; –

Balayage/Ombre Removal

If you mix Decolour Remover in a tint bowl and apply with a brush, it is possible to achieve a balayage or ombre colour removal effect. Here, you remove only the colour in the ends or balayage threads. Giving a multi-tonal/highlighted or ombre effect.

Quick Tip 

If you are currently block blonde and want to go to a lower maintenance natural shade, apply a 7.0 Medium Blonde Permanent Colourant throughout. Then immediately mix and apply Decolour Remover to just a few balayage threads and the very end sections. The newly applied colourant will remove in only these sections, exposing the previous blonde and creating a sun-kissed natural-dark blonde result. 

Partial Removal

As with a balayage or ombre removal, you need to mix in a plastic bowl and apply the colour remover with a brush.
However, a Partial Removal enables you to focus on specific sections only where the artificial colour may have become patchy or built up.

Quick Tip 

Dab Decolour Remover where you see the unwanted colour, watch as it reduces down and then rinse off when you appropriate level of removal has been achieved. 

Colour Reducer

This approach is ideal if you are happy with the overall colour but find the depth a little too heavy or the tone a bit intense.
Perhaps a red is too red, or an ash is too Smokey.

Quick Tip 

Clarify the hair and towel dry, apply Decolour Remover directly from the applicator bottle and immediately and quickly start to work through the damp hair. Observe the colour start to reduce in natural daylight and after a few minutes of development, proceed to rinsing the remover out of the hair. 

Another key aspect to success with Decolour Remover is understanding its limitations. Decolour Remover is for use on permanent oxidation colour molecules, and when used to eradicate these, results will be good. However, before using the product check, the following points do not apply to you;-

1. You have used a direct dye or fashion colour 

  • A Remover cannot work on direct dyes that did not feature a peroxide developer to activate. If any reduction agent colour remover is applied to a direct dye or fashion shade, the results would be unpredictable.


Instances where removal of a direct dye is required, please use Decolour Stripper.

2. Your hair has been bleached or lightened

  • When hair is bleached or lightened by hydrogen peroxide, the natural pigments have been lifted out of the hair. Therefore, you cannot restore them by applying a hair colour remover.

Quick Tip

If you have lightened and wish to return to your natural shade, you should apply a gentle tone on tone colourant one shade lighter than your natural colour.

3. You see a great deal of ginger, red or orange after using a permanent blonde or brunette colourant

  • Indicates the peroxide in the colourant applied was powerful, and your natural (underlying) colour has lightened, and your natural red and gold pigment is exposing through the hair. Therefore, using a hair colour remover for this issue will only reveal more warmth.

Quick Tip

Unwanted warmth and orange tone in an artificial hair colour should be neutralised. Use Colour Restore Cool Ash or Colour Restore Lilac Grey as your regular 2-minute conditioner and only wash your hair in a blue or purple shampoo. These changes to your hair care routine will keep warm tones at bay.

Colour Correction



Hair gone ginger?


Decolour Remover is only able to remove artificial permanent colour pigments. It contains no hydrogen peroxide and is not capable of lightening natural hair pigments. If you have removed and observed your natural colour has not returned. Instead, the hair appears to be warm, ginger or copper; this is indicating the permanent colourants you had previously applied have lightened your natural hair colour. All permanent colourants need hydrogen peroxide to function. However, some brands of permanent colour use much stronger peroxide volumes in the developer than others. Even black and dark brown hair colourants can feature peroxide strengths capable of lightening away natural pigment, as the new pigment deposits. This lightening of natural pigment is often not noticed until the unwanted permanent colour removes, then the lightened base is exposed. Quite often warm, as the natural red and gold pigment has been revealed.

How to remedy

The key with unwanted warmth is to neutralise and counteract. So, use a product like Colour Restore Cool Ash or Lilac Grey to balance out the exposed warm tones within the hair, and wash only in a blue or purple shampoo. These haircare approaches will cool exposed warmth and produce a neutral base shade.

Hair smells?


Decolour Remover contains an ingredient called a ‘Reduction Agent’. 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. 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.

How to remedy

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.

Hair has gone dark again?


When you have removed an unwanted dark hair colour, only to find the hair slowly darkens again over hours or overnight, this is indicating the (removed) hair colour is re-oxidising. Re-oxidation occurs when oxygen molecules (either atmospheric or in applied hydrogen peroxide) make contact with artificial colour molecules. This process is how the artificial permanent colour produced in the first instance. However, if you have removed an artificial colour and then experience re-oxidation, it means those reduced synthetic colour molecules did not effectively flush from the hair during the rinsing stage.

How to remedy

You will need to apply Decolour Remover again. However, when you get to the rinsing phase, make sure you rinse for at least 5 minutes under comfortable hot, steaming water. Steaming water ensures the hair cuticle raises open, enabling the reduced hair colour molecules to flush out thoroughly. To be doubly sure re-oxidation does not occur again, rinse for 5 minutes, then wrap hair in a towel and wait 30 minutes to an hour, then go back and rinse again for a further 5 minutes. By allowing the moisture inside the hair to evaporate a little, then returning to rinse again, there is far more chance of removing any stubborn artificial colour molecules.

Re-oxidation can be an entirely random phenomenon. Occasionally, a colourant shade appears on the market that can be prone to re-oxidation after removal. Also, naturally, Auburn hair tends to re-oxidise after the removal of darker colours because Auburn hair has a high sulphur content, which can prove more resistant to reduction agents found in hair colour removers and perms. For these reasons, always purchase two colour removers, to ensure a second is at hand if the first application does evoke re-oxidation.

Hair colour has not removed and has remained the same?


Generally, there are three reasons why it is perceived a hair colour remover application has not worked, and the hair has remained the same colour:

  • The hair had a build-up of silicones, residues and barriers and Decolour Remover could not enter the hair to evoke any change. In this instance, you should clarify the hair several times, do not apply any conditioner or styling products, then repeat the Decolour Remover applicator.
  • You have attempted to remove a direct dye (such as a bright fashion colour). Direct colours are notable because they do not require intermixing with a peroxide-based developer. Instead, they are just one bottle or tube applied directly to the hair. Hair Colour Removers work with oxidation technology only and are ineffective at removing direct dyes. Reduction agents (as found in hair colour removers) can react with direct dyes. It is, for this reason, we state on the box that Decolour Remover is not for the removal of any fashion colours or direct dye.
  • You have attempted to remove lightning in the hair. Decolour Remover can only reverse artificial permanent colour pigments; it cannot reverse lightening. Quite often people attempt to remove an unwanted red or copper tone in the hair, believing it to be from an artificial colourant applied, when in reality it is their natural red and gold pigment exposed from lightening via the peroxide developer in the colourant used.

In these situations, Decolour Remover would only expose more warmth or leave the hair colour unchanged.

Can I recolour immediately after using Decolour Remover?


Do not apply any peroxide-based colourants for at least seven days and three washes after using Decolour Remover. The reason being is the peroxide (found in the developer bottle) could evoke re-oxidation of the unwanted colour if it were applied to the hair too soon after removal. It is far better to wait a week and three washes, so allow any artificial colour molecules, remaining inside the hair to be flushed out and deactivated. However, you can use no peroxide direct dye colourants and toners immediately after using Decolour Remover.
