Purple Shampoo On Blue Hair

Maintaining blue hair can be tricky. Regular hair care options might not help much. However, have you ever considered purple shampoo? 

While it’s typically for blondes, its impact on blue hair is intriguing. Purple shampoo targets yellow-orange tones in blonde hair. But what about blue?

Let’s delve into this unconventional solution and uncover its potential to keep your blue hair looking vibrant and fresh.

Does Purple Shampoo Work on Blue Hair?

Yes, purple shampoo can work on blue hair. While its primary purpose is to neutralize yellow or orange tones in blonde hair, it can also help maintain the vibrancy of blue hair by counteracting any unwanted brassiness or fading. However, results may vary depending on the specific shade of blue and individual hair type.

About Purple Shampoo

Purple shampoo contains violet pigments, typically derived from ingredients like violet dye or violet leaf extract. These pigments neutralize brassy or yellow tones in hair. 

The science behind it lies in the colour wheel: purple sits opposite yellow on the wheel, so purple pigments cancel out yellow tones effectively. 

This process restores cooler tones, making blonde or gray hair appear brighter and more vibrant.


The primary advantages of purple shampoo include:

Neutralizing brassiness

Purple shampoo effectively neutralizes unwanted brassy or yellow tones in blonde, gray, or highlighted hair, restoring a cooler, more natural-looking shade.

Enhancing color vibrancy

Purple shampoo counteracts brassiness, helping to enhance the vibrancy and brightness of hair colour, prolonging the time between salon visits and preserving the desired hue.

Soothing colour-treated hair

Colour-treated hair can become dry or damaged over time. Purple shampoo often contains conditioning agents that help to nourish and hydrate the hair, leaving it soft, smooth, and manageable.

Effect on Different Hair Types

While purple shampoo is primarily designed for blonde, gray, or highlighted hair, its effectiveness can vary depending on individual hair types and colours:

Blonde hair: It is highly effective for neutralizing brassiness and maintaining the cool tones in blonde hair, whether natural or dyed.

Gray hair: It can also benefit individuals with gray hair, helping to prevent yellowing and maintain a clean, silver or white appearance.

Other hair colours: While purple shampoo may not be as effective on darker hair colours, it can still help to reduce unwanted warm undertones and enhance overall shine and brightness. However, frequent use may result in a slight violet tint, so monitoring its effects carefully is essential.

How to Use Purple Shampoo on Blue Hair

Choose the right purple shampoo

Select a purple shampoo specifically formulated for blonde or colour-treated hair. Look for products with violet pigments to effectively counteract any brassiness in your blue hair.

Wet your hair

Before applying the purple shampoo, wet your hair thoroughly in the shower. Ensure that your hair is saturated from roots to ends to allow the shampoo to distribute evenly.

Apply the purple shampoo

Dispense a small amount of purple shampoo into your palm and lather it gently onto your wet hair. Focus on massaging the shampoo evenly throughout your hair, paying extra attention to areas where brassiness tends to appear.

Let it sit for a few minutes

Allow the purple shampoo to sit on your hair for 3-5 minutes to allow the violet pigments to work their magic. Avoid leaving the shampoo on for too long to prevent any potential violet tinting.


Rinse your hair thoroughly with lukewarm water until the water runs clear. Ensure that all traces of shampoo are removed to prevent any residue buildup.

Comparison with Other Shampoos

If purple shampoo isn’t your go-to, here are some alternative options worth considering:

Blue shampoo

Tailored for blue hair, blue shampoos combat brassy and orange tones, especially ideal for darker or brunette shades. Like purple shampoos, they employ pigments—blue instead of purple—to achieve colour balance and potentially enhance blue hues.

Clarifying shampoo

Deeply cleansing clarifying shampoos eliminate product buildup, dirt, and oil. While beneficial for scalp health, they may strip hair colour more aggressively. If you have blue or dyed hair, use sparingly or opt for a colour-safe variant to retain colour vibrancy.

Sulfate-free and colour-safe shampoos

Sulfates can strip natural oils and dye, but sulfate-free alternatives preserve colour and moisture. Seek out shampoos explicitly labelled as colour-safe to safeguard your coloured hair’s longevity and vibrancy.

How do I maintain my blue hair colour?

Use a sulfate-free shampoo and cold water to wash your hair, as hot water and sulfates can strip colour. Limit washing to 2-3 times a week. Apply a colour-protecting conditioner or hair mask regularly to keep hair hydrated. Avoid excessive heat styling, as heat can fade colour. Additionally, touch up your roots as needed to maintain vibrancy.

Which shampoo prevents fading of blue hair?

Look for shampoos specifically formulated for colour-treated hair. These shampoos are typically sulfate-free and contain ingredients that help lock in colour, preventing premature fading. Opt for a gentle and moisturizing shampoo to keep your blue hair looking vibrant and healthy for longer.

Will purple shampoo cancel blue hair?

Purple shampoo is unlikely to cancel out the blue hair colour. Purple shampoo is formulated to neutralize yellow or orange tones in blonde hair, while blue hair tends to have cooler undertones. While purple shampoo may help tone down any brassiness or warmth in blue hair, it won’t completely cancel out the blue colour.

Can I put purple shampoo on blue hair?

Yes, you can use purple shampoo on blue hair to help maintain its vibrancy. While purple shampoo is not specifically designed for blue hair, its violet pigments can help neutralize any unwanted warm tones that may develop over time. However, be cautious not to leave the purple shampoo on too long, as it may impart a slight violet tint to your blue hair.


Purple shampoo emerges as a surprising ally if you’re daring enough to rock blue hair. Its magical violet pigments work wonders, neutralizing unwanted tones and preserving the bold brilliance of blue hues.

As we’ve journeyed through its mysteries, we’ve discovered the artistry behind maintaining vibrant blue hair.  Remember, in the colourful canvas of hair care, purple shampoo is the secret brushstroke that adds depth and brilliance to your blue masterpiece.
