Scott Cornwall Decolour Stripper is a two in one remover and lightener that removes all unwanted darker and tonal colour, whilst simultaneously lightening the underlying base to enable immediate re-colouring with a new chosen shade. The non-ammonia, conditioning formula is kind to the hair whilst enabling unwanted natural and artificial colours to be gently stripped away.

Creating a lighter hair colour and changing an existing colour effect is a broad undertaking and there are many reasons why someone might want to do this, including:

Strip both a natural and artificial colour

You want to remove both your artificial and underlying natural colour and replace with a different, lighter or tonal shade.

Wanting to go blonde

To get to a blonde shade, you must first lift the natural base and remove any artificial darker colour molecules.

Wanting to create a lighter brunette result

You might be a current dark base but want to switch to a lighter or multi-tonal brunette colour.

Lightening up dark roots for subsequent re-colouring

Often blonde hair colourants are not strong enough to lift dark natural roots, but bleach lighteners can be too harsh.

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

Decolour Stripper is a salon-inspired system that enables both colour cleansing and ultra-kind lifting and lightening of both natural and artificial colour pigments, without compromising of the hair. Decolour Stripper allows for something known in the salon industry as ‘Double Processing’.

What is Double Processing?

Double Processing is a technique commonly used in salons to achieve a perfect colour level and shade result. In the first process the hair is carefully stripped of its natural and artificial pigment, in the second process the stripped hair is re-coloured to the new desire shade. The key to Double Processing is the use of a very gentle lifting or colouring composition in either the first or second process. You cannot use a strong bleach in the first process if a strong colourant is used in the second process. Typically, salons will use a more potent bleach lightener in the first process, but then mix a bespoke gentle colourant for the second process. However, home bleaches and permanent colourants tend to operate on stronger levels. Meaning, someone could not Double Process successfully using these permanent products in the home.

Scott Cornwall wanted to remedy this issue and created Decolour Stripper for not only the removal of artificial hair colour shades but also the ability for individuals to conduct double process lightening and re-colouring, safely and effectively in the home.

How does Decolour Stripper work?

Decolour Stripper is a three-part system designed to remove both artificial and natural pigments, plus add strengthening proteins to the hair. The Part 1 De-Pigmenting Powder is a gentle lightening powder that operates on a lower PH to hair bleaches, so the cuticle is not swollen open during Processing compromising the hair quality. The peroxide developer contained within Decolour Stripper is only 6%, which is relatively low for a lightener. However, because the De-pigmenting powder can operate in a controlled, even manner, the hair can lift up to 5 levels in just one session, with less exposed warm pigment and reduced compromising to the hair. The Part 3 Conclude Balm contains plant proteins, the purpose of the Conclude Balm is to fill the central areas of the hair, strengthening and hydrating. This concluding protein step ensures that a subsequent second process permanent colourant can be applied to the hair without resulting in colour grabbing or damage.

Decolour Stripper has many uses which enable you to either strip, lighten or create the colours of your choice.

Blonde Root Lightening

Many blonde home colourants cannot lift natural hair shades by more than a few levels, before the advent of Hot Roots. Hot Roots are those bright copper or very orange roots that will not tone. By contrast, using traditional bleach on roots at home is too risky for non-professionals. However, by lifting the roots first with Decolour Stripper, before the application of any permanent blonde colour, you will not only achieve your desired blonde level, but as those roots grow in, the hair will retain strength.

Quick Tip 

Apply Decolour Stripper to the regrowth only on dry, clarified hair. Give the roots a full development and rinse off the Stripper and apply the Conclude Balm. 

Next, dry the hair 100% and repeat the regrowth application using your chosen blonde colourant, applying the colourant to only the lightened roots. Five minutes before development time concludes, dampen hair a little and comb the colourant throughout the hair, from the roots to the ends. 

Balayage Lightening 

Decolour Stripper is ideal if you desire balayage lightening within the hair. Mix in a tint bowl and using a tint brush, apply to fine threads throughout and leave to develop.

Quick Tip 

To create an ultra-naturalistic balayage in any base from black to medium blonde, proceed the use of Decolour Stripper with an application of a tone on tone colourant throughout in either a light brown (for natural darks) or light blonde (for natural blonde). This second process (known as camouflaging) mutes and blends the balayage threads into the surrounding base, creating a soft, naturalistic result. 

Fashion Colour Remover

Some fashion colours can prove stubborn to fade from the hair. However, hair colour removers (such as Decolour Remover) are not technically able to work on direct dyes. You can use Decolour Stripper in the removal of unwanted fashion colours. Just be mindful, fashion colours are generally applied onto bleached hair. And this type of base can often be fragile. For these reasons, always strand test before attempting to remove a fashion colour using Decolour Stripper.

Quick Tip 

Clarify the hair several times and carefully comb while still wet. Lightly wrap the hair in a towel, but do not towel dry. Move the towel from head to around the shoulders, allowing the wet hair to drop. Apply Decolour Stripper throughout the damp hair, starting on any areas where the unwanted fashion colour is particularly visible. Gently work through with a wide-toothed plastic comb and fingers. Spray the hair with water to distribute the Stripper into the hair and leave to develop before rinsing.

Another critical aspect to success with Decolour Stripper is understanding its limitations. Decolour Stripper is very gentle and designed to strip both natural and artificial colour pigments, creating a lighter canvas to re-colour. Therefore, be mindful of the following.

You have artificial black hair.

Decolour Stripper will not adequately remove unwanted artificial black pigment simply because black dyes contain too many colour pigments. Because Decolour Stripper is gentle, its development time will conclude before all the dark pigments have been removed.


Always remove unwanted black hair colour pigment with Decolour Remover. After removal of black hair colour using Decolour Remover, wait one week and seven washes before applying Decolour Stripper to go lighter still and change colour.

Decolour Stripper is NOT a destination shade.

Decolour Stripper is not a destination shade. The product was created to remove both natural and artificial pigment safely. Therefore, you will discover the hair has an apricot or yellow tone to it once the stripping is complete. Such a tone is entirely normal and is your canvas for the application of the subsequent, desired permanent colourant.

Quick Tip:

If you are unsure what lighter permanent shade you wish to go to; you can use Colour Restore immediately after using Decolour Stripper to create a no commitment semi-permanent result.  

Decolour Stripper is kind, but it should not be used on damaged, bleached hair.

While a Double Process Decolour Stripper + permanent colourant application is a kinder approach to traditional 8 level bleaching and toning, it must be understood that Decolour Stripper cannot reverse damage in bleached hair. Therefore, if your hair has suffered bleach or colour damage, you should not attempt to apply Decolour Stripper onto this hair. Instead, use a product like Colour Restore Instant Leave-In Toner Sprays daily, to build and strengthen the weak hair.

Colour Correction



Used Decolour Stripper, now hair is yellow!


This is totally normal. Decolour Stripper is not a colourant but a formula designed to remove both natural and artificial pigments from the hair. When an apricot or yellow shade is revealed, it is indicating all the colour pigments have removed and the colour of the hairs natural keratin fibres has been exposed. Keratin is yellow.

How to remedy

You must now proceed to the second step and re-colour the hair to the desired shade. If a pale or platinum blonde is desired, use Colour Restore Iced Platinum on this yellow hair to tone to a white blonde result. If the hair is naturally quite dark and has stripped to an apricot canvas, using a lightening blonde colourant featuring a cool tone, will also create a light blonde result.

Can I use Decolour Stripper as my regular blonde regrowth product?


Yes, Decolour Stripper is an ideal product to apply to dark regrowth to lighten the base safely. Always remember to mix and apply from a plastic bowl using a tint brush. Apply to dry hair only (not damp) onto just the dark regrowth. If you like a very shade specific blonde result, once the roots have been lightened, you can apply a second process blonde colourant onto the newly lightened areas, to create a deeper or more tonal blonde shade.

Quick Tip

If your dark roots tend to be stubborn at lifting, apply Decolour Stripper then loosely wrap a sheet of tin foil over your hair, creating a loose cap. This foil cap can be easily removed to check development and then placed back on if further development is needed. However, creating a foil cap will trap heat next to the roots and boost lifting.

Why is it recommended to apply the product to damp hair for whole head colour stripping?


The Decolour Remover formula has been manufactured to enable whole head hair colour stripping. In this process, all the natural and artificial pigment is stripped from the hair. To strip quickly and evenly; the mixed Decolour Stripper formula must be applied to damp hair. The dampness of the hair multiples the formula and causes the mixture to spread evenly throughout.

So, why is it recommended to apply the product to dry hair for balayage/ombre and regrowth application?


Because these are localised stripping applications, and you do not want the formula to start spreading throughout the hair when just the regrowth or specific balayage threads are being targeted. In addition, when the formula is applied to dry hair it will be slightly more potent, so balayage threads and regrowth sections will lighten more intensely.

Can I re-colour my hair immediately after using Decolour Stripper?


Yes, Decolour Stripper is designed for use immediately before application of any permanent or semi-permanent colourant. So, once an application of Decolour Stripper has concluded, you can immediately move onto the next colour application.

I regularly use fashion colours such as pink, blue and purple. Is Decolour Stripper a good product to use for maintaining my light base?


Yes. In fact, those who use Decolour Stripper to obtain their pale canvas for the application of fashion colours, often comment how they achieve more even, brighter colour results, less patching and experience consistent and total fade of semi-permanent shades. Decolour Stripper gently and evenly lightens the hair, therefore reducing the risk of porosity. Whereas very strong bleaches can cause hair to become highly porous. This extreme level of porosity can lead to colour staining from direct dyes, making fashion shades very difficult to remove from the hair. If Decolour Stripper is applied to regrowth only, every four to six weeks, the hair will retain a healthy pale canvas, that will accept direct dye pigments evenly and retain and fade off these pigments consistently.

Do I need to use the Conclude Balm with Decolour Stripper?


The Conclude Balm is a protein-based mask that is designed to enter the hair while it resides in a chemical state and fill any gaps within the hair cortex with proteins and moisture. Strengthening the hair, PH balancing, and buffering it for subsequent re-colouring. If the Conclude Balm step was emitted after use of Decolour Stripper and an ammonia-based or lightening colourant was immediately applied to the hair, there is a chance the hair would lift too much or damage could occur.
