What Is Colour Protect Shampoo and How Can It Help Your Hair?

 

If you colour your hair — whether that's a full dye, highlights, or a toner — you'll know how quickly that freshly-done vibrancy can start to fade. The Eight Triple Eight Colour Protect Shampoo 1L is a salon-inspired, everyday shampoo designed specifically for colour-treated hair. At just £3.99 for a full litre, it offers an accessible way to extend the life of your colour between appointments. You can find it alongside a wide range of other products in our hair care collection.

Colour-treated hair has a structurally altered cuticle — the outermost layer of each hair strand — which makes it more porous and more susceptible to pigment loss during washing. Using a shampoo that isn't formulated for dyed hair can strip colour faster than you'd expect. That's where a dedicated colour protect shampoo makes a real difference.

 

How Does Eight Triple Eight Colour Protect Shampoo Work?

 

The science behind colour protection in shampoo comes down to a few key mechanisms. Colour-safe shampoos are typically formulated at a slightly lower pH than standard shampoos, which helps keep the hair cuticle lying flat. When the cuticle is smooth and closed, colour molecules are less likely to escape during rinsing.

  • Gentle surfactants cleanse the scalp and hair without aggressively lifting the cuticle
  • A balanced pH helps seal the hair shaft after washing, locking in pigment
  • Conditioning agents coat the hair fibre, reducing friction and mechanical colour loss
  • The formula avoids harsh stripping agents that can accelerate fade in dyed hair

 

Who Should Use Eight Triple Eight Colour Protect Shampoo?

 

This shampoo is aimed at anyone who regularly colours their hair and wants to maintain that colour for longer. It's particularly useful if you find your colour fading within a week or two of your appointment, or if you wash your hair frequently. It's also worth considering if you're looking to reduce the frequency of salon visits — and the associated cost.

  • People with permanently dyed or bleached hair
  • Those with semi-permanent or toner-treated hair
  • Anyone with highlighted or balayage hair
  • Individuals with colour-treated hair who wash their hair two or more times per week

If you're also experiencing hair thinning alongside colour treatment, it may be worth exploring our female hair loss collection for additional support options.

 

How Does Eight Triple Eight Colour Protect Shampoo Compare to a Standard Shampoo?

 

Feature Eight Triple Eight Colour Protect Shampoo Standard Everyday Shampoo
Formulated for colour-treated hair Yes No
pH-balanced to protect cuticle Yes Varies
Gentle surfactant system Yes Often contains harsher sulphates
Volume (value for money) 1 litre at £3.99 Typically 250–400ml at similar or higher price

 

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 sensible to check the full ingredient list before trying any new hair product. Patch testing — applying a small amount to the inner arm and waiting 24 hours — is a reasonable precaution. This colour protect shampoo uses a gentle cleansing system, but individual sensitivities vary and no shampoo is universally suitable for every person.

Store the product 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 use the product once opened.

This product is a cosmetic. If you have an underlying scalp condition or skin disorder, speak to your pharmacist or GP before use.

Specifications of Eight Triple Eight Colour Protect Shampoo 1L

 

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

 

Eight Triple Eight Colour Protect Shampoo is a cosmetic hair care product designed to cleanse colour-treated hair while helping to preserve artificial pigment and maintain hair condition. It is used as a regular shampoo replacement for anyone whose hair has been chemically coloured, bleached, highlighted, or treated with a toner. The 1-litre size makes it practical for everyday use or for households where multiple people use the same product.

Colour-treated hair is more porous than untreated hair because the chemical colouring process opens the hair cuticle to deposit pigment. This increased porosity means colour molecules can escape more easily during washing, leading to faster fade. A colour protect shampoo helps address this by using a gentler cleansing system that minimises cuticle disruption during each wash.

 

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

 

Before using this shampoo, read the following precautions carefully:

  • Do not use if you have a known allergy to any ingredient listed on the packaging
  • Avoid contact with eyes — if contact occurs, rinse immediately with plenty of water
  • Do not apply to broken, irritated, or inflamed scalp skin
  • 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
  • Not intended for internal use — if swallowed, seek medical advice immediately

There are no known significant drug interactions associated with topical cosmetic shampoos. However:

  • If you are using medicated scalp treatments prescribed by your GP, check with your pharmacist before combining with any new shampoo
  • Avoid using alongside other leave-on chemical treatments without professional advice

 

How Should You Use Eight Triple Eight Colour Protect Shampoo?

 

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

  1. Wet your hair thoroughly with lukewarm water — hot water opens the cuticle and can accelerate colour fade
  2. Pour a small amount of shampoo (roughly the size of a 50p coin) into your palm
  3. Apply to the scalp first and work into a lather using your fingertips — avoid scrubbing with nails
  4. Work the lather gently through the lengths and ends of your hair
  5. Rinse thoroughly with cool or lukewarm water until all product is removed
  6. Repeat if hair is particularly dirty or if product build-up is present
  7. Follow with a colour-safe conditioner if desired
Hair Type Age Group Amount Frequency
Fine colour-treated hair Adults (18+) Small amount (~5ml) 2–3 times per week
Thick or long colour-treated hair Adults (18+) Larger amount (~10ml) 2–3 times per week
Colour-treated hair with oily scalp Adults (18+) Small to moderate amount Up to daily if needed

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

 

As with any cosmetic product applied to the skin, side effects are possible, though most people use shampoo without any problems. The NHS advises that allergic reactions to hair and scalp products, while uncommon, do occur and can range from mild irritation to more significant skin reactions.

Common side effects (may affect some users):

  • Mild scalp tingling or temporary dryness
  • Minor itching if the product is not rinsed out fully
  • Temporary scalp sensitivity after first use

Less common side effects (affect fewer users):

  • Allergic contact dermatitis — redness, swelling, or a rash on the scalp or hairline
  • Eye irritation if product accidentally contacts the eyes
  • Hair dryness if used more frequently than recommended without a conditioner

Stop using the product immediately if you develop a rash, hives, or significant scalp irritation. Seek advice from your pharmacist or GP if symptoms persist.

 

How Should You Store Eight Triple Eight Colour Protect Shampoo?

 

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep the cap tightly closed when not in use
  • Do not store in the freezer
  • Keep out of reach and sight of children
  • Check the period-after-opening (PAO) symbol on the packaging — typically indicated by an open jar icon with a number of months
  • Do not use after the expiry date printed on the bottle

How does colour protect shampoo work on dyed hair?

A colour protect shampoo uses gentle, low-pH surfactants that cleanse the scalp and hair without aggressively lifting the cuticle layer. When the cuticle stays smooth and closed, the artificial pigment deposited during colouring is less likely to escape during rinsing. Over time, this helps your colour stay vibrant for longer between salon appointments.

How do I use Eight Triple Eight Colour Protect Shampoo step by step?

Wet your hair thoroughly with lukewarm water, apply a small amount of shampoo to your scalp, and massage gently with your fingertips. Work the lather through the lengths of your hair, then rinse thoroughly with cool water. Repeat if needed, and follow with a colour-safe conditioner for best results.

How often should I use a colour protect shampoo?

Most people with colour-treated hair benefit from washing two to three times per week, as this balances cleanliness with colour longevity. Washing too frequently — even with a colour-safe formula — can still accelerate fade over time. If you have an oily scalp, you may wash more often, but try to use cool water and avoid vigorous scrubbing.

Can Eight Triple Eight Colour Protect Shampoo cause scalp irritation?

As with any shampoo, a small number of people may experience mild scalp irritation, itching, or redness — particularly if they have sensitive skin or a pre-existing scalp condition. If you notice any of these symptoms, stop using the product and consult your pharmacist or GP. Performing a patch test before first use is a sensible precaution.

Is Eight Triple Eight Colour Protect Shampoo suitable for all hair types?

This shampoo is formulated primarily for colour-treated hair, but it is generally suitable for most adult hair types including fine, thick, curly, and straight hair. If you have a diagnosed scalp condition such as psoriasis or seborrhoeic dermatitis, speak to your GP or pharmacist before introducing any new hair product. It is not specifically formulated for children's use.

What is the best time to use Eight Triple Eight Colour Protect Shampoo?

There is no clinically defined "best time" to shampoo colour-treated hair, but many hair care professionals recommend waiting at least 48–72 hours after a colour treatment before washing. This allows the colour to fully oxidise and settle into the hair shaft. After that initial period, use the shampoo as part of your regular routine whenever your hair needs cleansing.

What are the alternatives to Eight Triple Eight Colour Protect Shampoo?

Alternatives include other colour-safe shampoos from salon and pharmacy brands, many of which are available in our hair care collection. When comparing products, look at the pH level, whether the formula is sulphate-free, and whether it contains UV filters for additional colour protection. Eight Triple Eight offers excellent value at £3.99 for a full litre.

How long can I use Eight Triple Eight Colour Protect Shampoo for?

This is a cosmetic product with no maximum recommended duration of use — you can incorporate it into your hair care routine for as long as you colour your hair. Always check the period-after-opening symbol on the packaging, which indicates how many months the product remains suitable for use once opened. Discard the product if you notice any change in smell, colour, or texture.

Does Eight Triple Eight Colour Protect Shampoo contain sulphates?

The specific surfactant system used in Eight Triple Eight Colour Protect Shampoo is designed to be gentle on colour-treated hair. For precise ingredient information, always check the full ingredient list printed on the product packaging. If you are specifically seeking a sulphate-free formula, confirm this on the label before purchase.

Can I use Eight Triple Eight Colour Protect Shampoo if I have a sensitive scalp?

If you have a sensitive scalp, it is advisable to perform a patch test before using any new shampoo — apply a small amount to the inner arm and wait 24 hours to check for any reaction. People with diagnosed scalp conditions such as eczema or contact dermatitis should consult their GP or pharmacist first. The NHS recommends caution when introducing new hair and scalp products if you have a history of skin sensitivity.

Will colour protect shampoo stop my hair colour from fading completely?

No shampoo can prevent colour fade entirely — all artificial hair colour will fade gradually over time due to washing, UV exposure, heat styling, and the natural hair growth cycle. However, using a dedicated colour protect shampoo consistently can significantly slow the rate of fade compared to using a standard everyday shampoo. Combining it with a colour-safe conditioner and limiting heat styling will give the best results.

Is Eight Triple Eight Colour Protect Shampoo safe to use during pregnancy?

Cosmetic shampoos are generally considered safe for external use during pregnancy, but it is always sensible to check the ingredient list and consult your midwife or GP if you have any concerns. The NHS advises that some hair dye chemicals may carry a small risk during pregnancy, though this relates to the colouring process itself rather than maintenance shampoos. If in doubt, seek professional advice before use.

What should I do if Eight Triple Eight Colour Protect Shampoo gets in my eyes?

If the shampoo comes into contact with your eyes, rinse immediately and thoroughly with plenty of clean, lukewarm water for several minutes. If irritation, redness, or pain persists after rinsing, seek medical advice from a pharmacist, GP, or NHS 111. Always keep shampoo away from the eye area during use.

What are the latest recommendations for caring for colour-treated hair?

Current hair care guidance consistently recommends using pH-balanced, colour-safe shampoos, reducing wash frequency, using cool water, and minimising heat styling to preserve colour-treated hair. Nutritional support also plays a role — a balanced diet rich in protein, iron, and vitamins supports overall hair health, and you can explore relevant options in our vitamins and supplements collection. Always follow the aftercare advice given by your colourist for best results.

How Should You Use Eight Triple Eight Colour Protect Shampoo?

Using this shampoo correctly makes a genuine difference to how long your colour lasts. Always use lukewarm or cool water rather than hot, as heat opens the hair cuticle and encourages colour molecules to escape more quickly during rinsing.

What Is the Correct Dose of Eight Triple Eight Colour Protect Shampoo?

There is no fixed clinical dose for a cosmetic shampoo, but using the right amount for your hair type ensures effective cleansing without unnecessary product waste. Using too much shampoo does not improve colour protection and may require more rinsing, which can itself contribute to colour fade.

When Is the Best Time to Use Eight Triple Eight Colour Protect Shampoo?

Hair care professionals generally recommend waiting at least 48–72 hours after a colour treatment before washing your hair for the first time. This allows the colour to fully oxidise and settle into the hair shaft, which helps the pigment last longer. After that initial period, use the shampoo whenever your hair needs cleansing as part of your regular routine.

There is no specific time of day that is clinically superior for shampooing colour-treated hair. However, if you use heat styling tools, shampooing before styling — rather than after — means your hair is freshly cleansed and you can apply heat protectant to clean hair.

How Long Can You Use Eight Triple Eight Colour Protect Shampoo For?

As a cosmetic product, Eight Triple Eight Colour Protect Shampoo can be used as part of your ongoing hair care routine for as long as you continue to colour your hair. There is no recommended maximum duration of use. Always check the period-after-opening (PAO) symbol on the packaging — this tells you how many months the product is suitable for use after first opening. Do not use the product after its expiry date or if you notice any change in its smell, consistency, or appearance.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

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

Most people use colour protect shampoo without experiencing any side effects. However, as with all cosmetic products applied to the skin and scalp, mild reactions can occasionally occur, particularly during first use or if you have naturally sensitive skin.

  • Mild scalp tingling or temporary tightness after washing
  • Minor itching if the product is not rinsed out completely
  • Temporary scalp dryness, particularly if used more frequently than recommended
  • Slight hair dryness if used without a conditioner on very porous or bleached hair

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

Less commonly, some individuals may experience a more noticeable reaction to one or more ingredients in the formula. These reactions are more likely in people with a history of contact dermatitis or known cosmetic ingredient sensitivities.

  • Allergic contact dermatitis — presenting as redness, swelling, or a rash along the hairline, scalp, or neck
  • Eye irritation if the product accidentally contacts the eyes during rinsing
  • Localised urticaria (hives) in individuals with a specific ingredient allergy

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

Serious reactions to cosmetic shampoos are rare but can occur. Signs of a significant allergic reaction include rapid onset of swelling around the face, lips, or throat, difficulty breathing, or widespread hives. These symptoms may indicate anaphylaxis, which is a medical emergency. Call 999 immediately if you or someone else experiences these symptoms after using any cosmetic product. The NHS advises that anyone with a history of severe allergic reactions should exercise particular caution when trying new personal care products.

What Should You Do If You Experience Side Effects?

If you notice mild irritation such as itching or redness, rinse the product off immediately with plenty of cool water and discontinue use. Do not reintroduce the product if symptoms recur. For persistent or worsening skin reactions, contact your pharmacist or GP, who can advise on appropriate treatment — which may include a topical corticosteroid cream for contact dermatitis. Always bring the product packaging to your appointment so the clinician can review the ingredient list.

Can Eight Triple Eight Colour Protect Shampoo Interact With Other Products?

There are no known significant interactions between cosmetic shampoos and oral medicines. However, if you are using a medicated scalp treatment prescribed by your GP — such as a corticosteroid scalp application or an antifungal shampoo — check with your pharmacist before combining it with any new cosmetic shampoo. Using multiple active scalp products simultaneously without guidance may affect the efficacy of the medicated product or increase the risk of scalp irritation.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
