Hair care has evolved tremendously, offering various products tailored to specific needs. Among the wide range of hair care solutions available, blue shampoo stands out, especially for those looking to neutralize unwanted tones and maintain a vibrant hair color. Often misunderstood or confused with purple shampoo, blue shampoo can make a notable difference in hair appearance, particularly for brunettes who struggle with brassiness. In this article, we’ll delve deep into how blue shampoo works to lighten hair, the science behind its efficacy, and the differences between blue and purple shampoos. You’ll gain insights into proper usage, notable brands, and everything else you need to know to keep your hair looking its best.

What is Blue Shampoo?

Blue shampoo is a toning hair product designed specifically for brunettes with highlights, balayage, or naturally lighter hair that tends to turn brassy over time. The primary function of blue shampoo is to neutralize orange and red tones, which can appear in brunette hair due to exposure to the sun, environmental pollutants, and chemical treatments like bleaching. The blue pigments in the shampoo counteract the warm tones, thereby maintaining the hair’s cool undertones.

Difference Between Blue Shampoo and Purple Shampoo

While both blue and purple shampoos are toning products, they are targeted at different hair colors and toning needs. Purple shampoo is most effective for blonde, white, or gray hair. It contains purple pigments to counteract yellow undertones that often plague lighter hair shades. On the other hand, blue shampoo is specifically designed for darker hair colors. The blue pigments neutralize orange and red tones in brunette hair, offering a different kind of toning effect.

The key difference lies in the complementary colors on the color wheel. Purple is opposite yellow, making it ideal for canceling out yellow tones in lighter hair. Meanwhile, blue is opposite orange, which makes blue shampoo perfect for brunettes combating brassiness.


To achieve the best results with blue shampoo, it’s important to follow proper usage instructions. Generally, it’s recommended to use the shampoo a few times a week in place of your regular shampoo. Here’s a step-by-step guide on how to use it:

  • Wet your hair: Start with wet hair to ensure the shampoo spreads evenly.
  • Apply blue shampoo: Squeeze a generous amount of blue shampoo into your hands and lather it into your hair, focusing on the areas with the most brassiness.
  • Leave it on: Allow the shampoo to sit for 3-5 minutes to allow the pigments to actively work on neutralizing the unwanted tones. Be cautious not to leave it on for too long, as it may over-tone your hair.
  • Rinse thoroughly: Rinse the shampoo out thoroughly to prevent any residue from affecting your hair texture.
  • Condition: Use a hydrating conditioner to restore moisture to your hair, which can be stripped by the toning process.

The success of blue shampoo in lightening hair and neutralizing brassy tones comes down to its powerful pigments. Pigments are colored substances that help to cancel out specific colors in your hair. In blue shampoo, the pigments are blue because blue is the complementary color to orange on the color wheel. When you apply the shampoo to brassy hair, the blue pigments attach to the orange tones, effectively canceling them out and resulting in a cooler, ashier shade.

The pigments are designed to be temporary and wash out gradually with regular shampoo use, which is why it’s advisable to continue using blue shampoo regularly if you want to maintain the effect. It’s important to note that while blue shampoo can help lighten the appearance of your hair by neutralizing warm tones, it doesn’t physically bleach or lighten the natural pigment of your hair.


There’s a variety of blue shampoos on the market, each offering unique benefits and features. Here are some notable options:

  • Joico Color Balance Blue Shampoo: Renowned for its effective neutralizing properties, Joico’s blue shampoo is highly recommended for brunettes dealing with severe brassiness.
  • Fanola No Orange Shampoo: This product is potent and provides quick results. It’s ideal for both natural and chemically-treated brunette hair.
  • Matrix Total Results Brass Off Shampoo: Matrix offers a well-balanced formula that not only tones down brassy hues but also strengthens and nourishes the hair.
  • Redken Color Extend Brownlights Blue Toning Shampoo: Specifically designed for both colored and natural brunette hair, Redken’s formula works to provide long-lasting toning effects and color correction.
  • dpHUE Cool Brunette Shampoo: This blue shampoo is a favorite for its gentle formula that’s sulfate-free, ensuring it doesn’t strip your hair of essential moisture.

Choosing the right brand will depend on your specific hair needs and how much brassiness you’re dealing with. It’s always a good idea to read reviews and perhaps even speak with a hair care professional for personalized advice.


Blue shampoo is an essential tool for brunettes looking to keep their hair free from unwanted brassy tones. Distinct from purple shampoo, which is designed for blondes, blue shampoo uses blue pigments to neutralize orange and red tones in darker hair. Regular use of blue shampoo, following the proper guidelines, can help maintain a cooler, more vibrant hair color. While many brands offer blue shampoo with different features, the fundamental benefits remain the same: a cooler, more natural-looking brunette shade free from brassy undertones.

Understanding the Composition of Blue Shampoo

Blue shampoo is specifically formulated to address the unique needs of individuals with brunette or darker-toned hair. It primarily targets brassiness, the undesired yellow or orange tones that often emerge after hair coloring or prolonged sun exposure. To understand how blue shampoo works, it is essential to delve into its composition.

The primary active ingredient in blue shampoo is **blue-violet pigment**. This pigment works on the principle of color theory, where blue cancels out orange and yellow tones. When applied to hair, the blue pigments adhere to the hair shaft, neutralizing the brassy colors and leaving the hair looking cooler and more balanced.

Beyond the pigments, blue shampoo formulations often include a variety of other ingredients that contribute to its effectiveness. **Surfactants**, for instance, are compounds that help to cleanse the hair and scalp by removing dirt and excess oil. These surfactants are carefully chosen to ensure they do not strip the hair of its natural moisture, which is crucial for maintaining healthy hair.

Moreover, many blue shampoos are fortified with conditioning agents such as **panthenol (Vitamin B5)** and natural oils, like **argan or jojoba oil**. These ingredients help to keep hair hydrated and smooth, countering the drying effects that can sometimes accompany the use of pigment-depositing shampoos. Hair is left not only looking better in terms of color but also feeling softer and more manageable.

Another vital component is the **pH level** of the shampoo. Blue shampoos are generally formulated to be slightly acidic, as this helps to close the hair cuticle, adding shine and reducing frizz. A closed cuticle also ensures that the blue pigment adheres better and lasts longer, making the color-correcting effects more durable.

Optimal Hair Care Routine When Using Blue Shampoo

To achieve the best results when using blue shampoo, it is important to incorporate it into an optimal hair care routine. Unlike regular shampoos, which can be used daily, blue shampoos are most effective when used selectively and strategically.

Frequency of Use

Firstly, it’s recommended to use blue shampoo **once or twice a week**, depending on the extent of brassiness and the natural color of your hair. Overuse can lead to over-toning, where the hair might start to take on a blue tint rather than simply neutralizing unwanted tones. Therefore, moderation is key.

Application Process

1. **Wet Hair Thoroughly:** Before applying blue shampoo, make sure your hair is thoroughly wet. This helps to evenly distribute the product and ensures better penetration of the pigments.
2. **Lather and Apply:** Use a generous amount of shampoo, lather it in your hands, and apply it evenly throughout your hair. Focus particularly on areas where brassiness is most prominent, such as the mid-lengths and ends.
3. **Leave In:** Leave the shampoo in your hair for **3-5 minutes** to give the blue pigments enough time to counteract the brassiness effectively. However, keep in mind that leaving it on for too long may result in an unintended blue tint.
4. **Rinse Thoroughly:** Rinse the shampoo thoroughly to ensure all residues are washed out. This step is crucial, as leftover pigments can continue to deposit color, leading to uneven results.
5. **Condition:** Follow up with a good conditioner or a hair mask to restore moisture and seal the hair cuticle. Many brands offer conditioners specifically designed to complement blue shampoos, enhancing the toning effects while providing essential hydration.

Additional Hair Care Tips

– **Weekly Treatments:** Incorporate regular nourishing treatments into your routine. Weekly deep conditioning treatments or hair masks can help mitigate the drying effects of color treatment and pigment-depositing shampoos.
– **Heat Protectant:** Using a heat protectant before styling can prevent further damage and maintain the health and appearance of your hair.

By understanding the proper usage and integrating blue shampoo into a thoughtful hair care routine, you can effectively neutralize brassiness and maintain a cool, vibrant hair color.
