How to use purple shampoo

White and platinum hairstyles have been increasing in popularity in recent years and while they can look stunning, the upkeep can take a lot of work.

Particularly in between salon appointments as the colour starts to fade, or pollution and hair products leave it looking yellow or brassy.

This is where purple shampoo comes in.

Heat styling, the sun and living in an area with hard water can all make bright blondes appear dull, brassy and yellow.

You, therefore, need a corrective shampoo to undo this change.

Below we explain more about purple shampoo and list what we consider to be the best purple shampoos and corrective drops on the market.

1. Editor’s Pick: The Hair Boss Corrector Drops of Blonde Hair

£8.20 | BUY NOW

Why we love it: These corrector drops from The Hair Boss are the best way to control how much pigment you’re putting on your hair, without causing too much staining and mess.

Using these drops also means you can control your brassy tones while still using your favourite shampoo or conditioner products. This is especially key if you’re trying to avoid SLS-based products, or you have sensitive skin on your scalp.

Add a few drops (depending on the desired tone you want for your hair) to your shampoo, conditioner or hair mask in the palm of your hand. Apply this to damp/towel-dried hair, leave for five minutes and rinse well.

We recommend that if you’re not sure how much to use, start off with a small amount and build it up to your desired tone.

2. L’Oreal Elvive Colour Protect Anti-Brassiness Purple Shampoo

£6 | BUY NOW

Why we love it: L’Oreal Elvive Colour Protect is another popular choice for neutralising highlighted brunette, blonde and grey hair. Massage this shampoo into your hair and leave for 1-3 minutes and then follow with the Purple Conditioner.

This shampoo removes brassiness and adds shine, which makes your hair look even brighter.

4. Olaplex No.4P Blonde Toning Shampoo

£28 | BUY NOW

Olaplex No 4P Blonde Enhancing Toning ShampooOlaplex

Why we love it: If you’re a fan of Olaplex treatments, or you’re looking for a way to fix your hair while enhancing your blonde, Olaplex No.4P is a great, albeit expensive, choice. It uses the same hair repair ingredients found in its treatments with purple hair toner added to the mix.

Toner has a tendency to dry the hair out, especially when it’s applied to bleached hair that is already dried and damaged. This means the addition of bond-building technology in the Olaplex shampoo is a huge bonus.

Olaplex claims its shampoo has been designed to “leave blondes three times brighter than regular purple shampoos” and in our experience this is accurate. In fact, it lifts your blonde hair after a single use. Just don’t just leave it on for too long because it’s really strong and will leave your hair looking silver.

To enhance the effect, Olaplex recently released a purple conditioner.

5. Moroccanoil Blonde Perfecting Purple Shampoo

£20.85 | BUY NOW

Why we love it: If you have icy blonde hair, in particular, or your hair is particularly dry following all the bleaching and hair dye, then this is the shampoo for you.

With the help of deep violet pigments in the shampoo to help neutralise and correct harsh brassy tones it leaves the hair bouncy. What we love about this shampoo is that it gives hair a deep cleanse but it doesn’t strip the hair of essential oils, it just leaves the hair natural and soft.

6. John Frieda Violet Crush Intensive Purple Shampoo

£7.99 | BUY NOW

Why we love it: This is a firm highstreet favourite. John Frieda’s Violet Intensive Purple Shampoo neutralises stubborn brassy tones in one use for a highly affordable price.

This weekly shampoo will help keep blondes cool and will give the appearance of brighter blonde-looking hair. It’s safe for use on natural, colour-treated, platinum blonde, and lightened brunette hair.


7. Redken Color Extend Blondage Shampoo

£23.90 | BUY NOW

Why we love it: Eliminate yellow undertones, Redken Color Extend Blondage has infused ultra-violet pigments to help with the yellow undertones. Massage into wet hair, lather it up and leave for 3-5 minutes and rinse.

It balances yellow-toned hair without drying it out and it keeps blonde/highlighted hair fresh and vibrant. It’s almost like a refresh of colour every time it’s used. The added bonus is that hair feels soft and manageable, as is the case with Redken products generally. We rate them highly.

8. L’Oreal Professionnel Series Expert Silver Shampoo

£16.50 | BUY NOW

Why we love it: If you have metallic or platinum hair, in particular, this silver shampoo is ideal. It will help reduce unwanted brassy tones and leaves hair with a lovely glow and a soft feel to it. To get the most vibrancy, we recommend leaving it on for five minutes.

What is purple shampoo?

As its name suggests, purple shampoo is a shampoo with purple pigments in it. Due to this, it typically looks dark purple in colour. The reason it’s so dark, and has a tendency to stain your hands and towels, is that it requires a lot of pigment to really lift the colour of the blonde hair.

What does purple shampoo do?

The purple pigments in purple shampoo counteract the orange and yellow tones in brassy, dull hair and this down to what’s known as colour theory.

As you can read in our colour theory and makeup guide, colours that sit opposite each other on the colour wheel are what’s known as complementary colours. When two complementary colours are placed next to each other, they contrast and can be used to accentuate certain features – like your eye colour. However, when they’re mixed together, they help to cancel each other out by neutralising the strength of each of the colours.

Purple is opposite yellow on the colour wheel, which is why purple shampoo helps to neutralise yellow tones. Similarly, it’s why blue shampoo helps lift the colour of brunette hair. Both are effectively acting as hair toner.

How to use purple shampoo

We spoke to Lisa Shepherd, founder of The Hair Boss about corrective shampoos and how to use purple shampoo. She said that the problem of using any form of corrective shampoo comes when they’re overused.

Purple shampoo shouldn’t be used every time you wash your hair, it should be used once or twice a week maximum. Using it too much will actually start making blonde hair go a grey/grape colour.

“It’s important to keep the blonde clean and ‘detoxed’,” Lisa continued. “It’s also important to keep brassy tones at bay, but any corrective product should work alongside a healthy prescribed hair and scalp regime. This includes scrubbing, cleansing, conditioning and styling.”

She explained that you shouldn’t wait until brassiness appears and purple shampoos should be used as a preventative measure as much as anything.

“For years I wished we could just control the level of tone within the shampoo as that would be fab but most shampoos are pretty generic and it’s a one-size-fits-all approach, which as we know, is just not how hair works.”

Rather than selling purple shampoos, The Hair Boss sells corrector drops that can be added to regular shampoos, conditioners or even styling creams as often or as little as you feel the need. This allows you to maintain and control the tone you want without unnecessary build-up.
