Eight Triple Eight Colour Protect Shampoo 1L

What Is Eight Triple Eight Colour Protect Shampoo?

If you colour your hair — whether that's a full dye, highlights, or a toner — you'll know how quickly that fresh-from-the-salon vibrancy can start to fade. Everyday washing is one of the biggest culprits. That's where a dedicated colour protect shampoo makes a real difference. Eight Triple Eight Colour Protect Shampoo 1L is a salon-sized, everyday cleanser formulated specifically for colour-treated hair, helping to preserve your shade for longer while keeping your scalp and lengths clean. At just £3.99 for a full litre, it's an accessible option for anyone who wants to look after their colour without spending a fortune. You can browse the full range of hair products in our hair care collection.

Colour-treated hair has a different structure to untreated hair. The dyeing process opens the hair cuticle to deposit or remove pigment, which can leave the cuticle slightly raised and more porous. This means colour molecules can escape more easily during washing, leading to faster fade. Using a shampoo designed for this purpose helps address that vulnerability directly.

How Does Eight Triple Eight Colour Protect Shampoo Work?

The mechanism behind colour protection in shampoo comes down to a few key principles:

• Gentle surfactants: Milder cleansing agents are used instead of harsh sulphates, which can strip colour from the hair shaft more aggressively.
• Low-pH formulation: A slightly acidic pH helps keep the hair cuticle lying flat, reducing the gap through which colour molecules can escape.
• Conditioning agents: These coat the hair shaft, adding a layer of protection and reducing friction that can physically damage colour-treated strands.
• Reduced colour leaching: By minimising the swelling of the hair shaft during washing, less pigment is lost with each wash cycle.

None of this is magic — it's straightforward hair science. The shampoo won't reverse existing fade, but used consistently from the moment you colour your hair, it can meaningfully extend the life of your shade.

Who Should Use Eight Triple Eight Colour Protect Shampoo?

This shampoo is designed for anyone with chemically coloured hair, but it's worth knowing exactly who benefits most. It's a gentle enough formula for regular use, and the 1-litre size makes it practical for households where more than one person colours their hair.

• People with permanent or semi-permanent hair dye who want to extend colour vibrancy
• Those with highlighted, bleached, or toned hair that is prone to brassiness or fading
• Anyone looking for a cost-effective, everyday colour-safe shampoo
• Individuals with dry or chemically processed hair who need a gentler cleansing option

If you're also dealing with hair thinning or loss alongside colour-treated hair, it's worth exploring our female hair loss collection for additional support options.

Is Eight Triple Eight Colour Protect Shampoo Suitable for Sensitive Scalps?

If you have a sensitive scalp or a history of contact dermatitis, it's always worth checking the full ingredient list before trying any new hair product. The NHS advises that allergic contact dermatitis on the scalp can be triggered by ingredients in hair care products, including fragrances and preservatives. If you notice redness, itching, or flaking after use, stop using the product and speak to your pharmacist or GP.

For most people with colour-treated hair, this colour protect shampoo is well-tolerated as part of a regular washing routine. Store the bottle below 25°C, away from direct sunlight, and keep it out of reach of children. Check the period-after-opening symbol on the packaging for guidance on how long to keep it once opened.

This product is a cosmetic shampoo. Speak to your doctor or pharmacist before using if you have an underlying scalp condition or known skin sensitivities.

What Is Eight Triple Eight Colour Protect Shampoo and What Is It Used For?

Eight Triple Eight Colour Protect Shampoo 1L is a topically applied cosmetic hair cleanser designed for use on colour-treated hair. Its primary purpose is to cleanse the scalp and hair while minimising the loss of artificial colour pigment that can occur with regular washing. It is not a medicinal product and does not treat any medical condition. It is used as part of a regular hair-washing routine to help maintain the vibrancy and longevity of hair dye, whether permanent, semi-permanent, or toned.

What Do You Need to Know Before Using Eight Triple Eight Colour Protect Shampoo?

Before using any new hair care product, it's sensible to be aware of the following contraindications and precautions:

• Do not use if you have a known allergy to any ingredient listed on the packaging
• Avoid use on broken, inflamed, or infected scalp skin
• Not intended for use on children without adult supervision
• If you have a diagnosed scalp condition such as psoriasis, seborrhoeic dermatitis, or eczema, consult your GP or pharmacist before use
• Keep out of reach of children
• For external use only — do not swallow

Regarding interactions, this is a cosmetic product and is not known to interact with medicines. However:

• Using alongside other leave-in chemical treatments (e.g. keratin treatments or relaxers) may affect performance — check compatibility with your stylist
• If you are using a medicated scalp treatment prescribed by your GP, apply that separately and seek advice on timing

How Should You Use Eight Triple Eight Colour Protect Shampoo?

Using this shampoo correctly will help you get the most out of it. Follow these steps each time you wash your hair:

1. Wet your hair thoroughly with warm (not hot) water — hot water opens the cuticle and can accelerate colour fade
2. Pour a small amount of shampoo into your palm — roughly the size of a 10p coin for short hair, slightly more for longer hair
3. Apply to the scalp first and work into a lather using your fingertips (not nails)
4. Gently work the lather down through the lengths of your hair
5. Leave for one to two minutes if possible, then rinse thoroughly with cool or lukewarm water
6. Repeat if hair is particularly dirty, but note that a second wash is rarely necessary for colour-treated hair
7. Follow with a colour-safe conditioner for best results

What Are the Possible Side Effects of Eight Triple Eight Colour Protect Shampoo?

As with all cosmetic hair products, side effects are uncommon but possible. The NHS notes that allergic reactions to hair care products, particularly those containing fragrances or preservatives, can occur in some individuals. If you experience any of the following, stop use immediately.

Common side effects (may affect some users):

• Mild scalp dryness, particularly if used more frequently than recommended
• Temporary scalp tingling or sensitivity on first use
• Minor product build-up if not rinsed thoroughly

Less common side effects:

• Allergic contact dermatitis — redness, itching, or a rash on the scalp, forehead, or neck
• Eye irritation if product enters the eyes — rinse immediately with plenty of water
• Hair texture changes if used in combination with incompatible chemical treatments

If you develop a severe allergic reaction — including swelling of the face, lips, or throat — seek urgent medical attention. You can find further guidance on managing skin reactions through our skin care collection.
