Blue shampoos are meant for brunettes (or people with dark colored hair) whose hair succumbs to brassiness when they choose to bleach or lighten their hair color. 

While brunette’s lighten their hair, there could be underlying natural hair pigments of orange, reddish-orange or copper that tend to show up in the hair. That’s when a blue shampoo comes into play.

On the other hand, purple shampoos are meant for blondes (or people with lighter colored hair like silver, ash, platinum etc), when their hair develops brassy tones like yellow or yellowish-orange. That’s when they’d require you to use a purple shampoo.

Blue and purple shampoos are helpful in the removal of brassy tones from the hair and also further retaining the vibrancy of the hair color over time and keeping it from fading. 

Well, because salon trips can become rather expensive and using these shampoos can do the trick for you.

Why Should I Use A Blue/Purple Shampoo

Hair brassiness can be a result of many factors. Here are some of the reasons as to why your hair could have turned brassy.

Firstly, if you’re a brunette and decided to dye your hair blonde or any other lighter shade, then obviously you’d have to bleach it before that. 

Now, in the process, after your hair got bleached, you soon realize your hair has turned orange to your horror! 

Well, don’t worry, as this is a normal and common problem that occurs in many people. 

Brassiness mostly occurs because you didn’t leave the bleach on for the right amount of time and therefore, the color didn’t lift off correctly, letting the warmer undertones of your hair show up.

Secondly, if you’re a blonde and tend to use hard water to wash your hair or often go swimming, the mineral deposits in the water can cause the minerals to get stuck onto your hair shaft, causing your hair to become brassy.

Lastly, if your hair is overexposed to sunlight, it will fade over time and then it may begin to look brassy.

So this is the reason why you need a blue or purple shampoo as blue neutralizes the orange pigments in hair and removes brassiness. 

And purple removes yellow undertones making warm blonde/brunette hair look “cooler”.

I’m sure most of you must be wondering why brunettes should use a blue shampoo and blondes a purple shampoo. Why will a regular shampoo not work?

Well, it is important to keep in mind the importance of the color wheel whenever we talk about brassy tones in hair.

So, what is the color wheel? The color wheel shows us a spectrum of colors and is placed in a specific manner. You will notice that half the color wheel has warm colors, while the other half has cool colors.

Now when the warm pigments like orange, copper or yellow overpower the cool pigments in the hair, we notice brassiness. 

Therefore, the only way we can get rid of this brassiness is by neutralizing and balancing out these warm pigments. 

In order to neutralize these warm pigments, we require to pick the colors opposite to the color we want to neutralize.

So, in this case, a blue shampoo will neutralize the orange or copper tones in the hair, while a purple shampoo will neutralize the yellow tones in the hair.

  • Remember to buy a shampoo that is thick in consistency and is opaque in color, not translucent or transparent.
  • Find a shampoo that is free from harsh chemicals like sulfates, parabens etc. This is especially for color-treated or bleached hair, because the hair is already likely damaged to a certain extent and using a shampoo with chemicals will only create more damage to the hair.
  • Look for shampoos that are salon-grade or of high quality (which are used by professionals), even though they may be a little expensive.
  • Search for products that have high customer ratings with good reviews, if you aren’t buying it from a store.

Yes, using a blue or purple shampoo will require nothing additional as compared to washing your hair with a regular hair washing shampoo. It is just as simple and easy -to-use.

All you need to do is rinse your hair properly under running water and let it get completely wet before shampooing it. 

Using warm water is recommended, so that the cuticles on the hair shaft will get raised and the blue or purple shampoo will penetrate properly into the hair strand, making the product work more effectively.

Then, use a sufficient amount of shampoo so that all your hair is covered and lather it well, gently massaging it into your hair and then leave it on for a few minutes.

For those who have a lot of brassiness in their hair, you will have to keep the shampoo on for longer, but for a maximum of 15 minutes per hair washing session. 

If your brassiness hasn’t completely gone away, then try to repeat shampooing your hair another time, until the brassiness goes away.

Lastly, wash off the shampoo properly and condition your hair well.
