How To Use Blue Shampoos 2023 | A Simple Guide To Toning Shampoos

Here’s an easy guide on how to use blue shampoos for toning your brassy brunette or blonde hair. Check out how often you need to use this shampoo and if you can use it with regular conditioner.  

A lot of people are now dyeing their hair at home, but the thing is and there are several resources available to help them color their strands well.

But not a lot of people know about hair toning.

Believe it or not toning your hair is as important as dyeing it the right shade. A lot of hair colors (especially bleached blonde tones) fade with time. 

And this can often lead to something called “brassiness”. This is nothing but the presence of warm undertones on hair.

In blonde hair, this can be seen as an abundance of orange giving bleached hair a “coppery” or strawberry blonde look.

But these warm undertones are not as visible on brown hair. On brunette tresses these undertones might appear as reddish auburn highlights. 

While some people like this look and keep them, others prefer a cool “Ash” brown shade. So in that case, a blue shampoo comes handy.

What Is Blue Shampoo Used For?

Blue shampoo works on the principle of color theory. In the color wheel, blue is opposite to orange. So adding blue pigments to your tresses can reduce the orange and coppery undertones. 

A blue shampoo is used to reduce the brassiness and coppery undertones from your hair by neutralizing the warm pigments. 

Blue shampoo is often used by colorists after bleaching hair so that the brassiness is removed from blonde hair. 

But nowadays women are using it as a way to reduce the reddish undertones in brown hair as well as a cooler ash shade of hair is in trend. 

How To Use Blue Shampoos

Here is a step by step guide on how to use blue shampoos effectively. Check it out! 

Step 1: Wet Hair Thoroughly And Apply Blue Shampoo

There is actually very little difference between a blue shampoo and a regular shampoo except for the presence of color pigments. 

So you can use a blue shampoo the same way you use regular shampoos. You do not have to wash your hair separately before using a blue shampoo.

The only difference here is that you have to apply the blue shampoo on your roots AND the ends of your hair. Doing so will ensure the blue pigment coats hair effectively. 

Step 2: Massage Shampoo In And Let It Sit On Hair

Another difference between regular shampoos and a blue shampoo is that you need to leave blue shampoos on hair for some time before washing it off. Think of it as a shampoo cum hair mask. 

Most blue shampoos have different instructions regarding this, but I generally keep the blue shampoo on my hair between 5-10 minutes. 

This time also depends on the porosity of your hair. People who have high porosity hair can leave blue shampoos on for just 3-5 minutes and it will still work just fine. 

These hair types absorb pigments quicker than others due to the placement of the cuticles on hair strands.

However, low porosity hair doesn’t allow pigments (or for that matter anything) to penetrate cuticles easily. So I suggest giving it more time if you have such a hair type. 

Pro Tip: Use warm water to wet your hair to slightly open up your cuticles before applying blue shampoo. This will ensure the pigments penetrate the strands of hair more efficiently. 

Step 3: Rinse It Off With Cool Water

After you’ve left the blue shampoo on for the designated period, it’s time to rinse it off! 

Here’s another great hair hack for you! Remember when I said you should wash your hair with warm water first to open up the cuticles? Well, it’s time to do the opposite now. 

Rinse your hair with cool water to wash off the shampoo. This will close hair cuticles and leave hair smoother and frizz-free.

Step 4: Follow It Up With Blue Conditioner If Needed

Now comes the conditioning part! While it’s completely okay to use your regular conditioner on your hair after washing it with blue shampoo, you can also try a blue conditioner.

Yes. Blue conditioners exist as well! 

These are color-depositing conditioners that add blue pigment to your hair to remove brassiness similar to blue shampoos. 

However, only go for blue conditioners if you have a lot of orange-coppery tones on hair and need a strong toner to remove them. 

Using too much blue shampoo and conditioner can actually leave your hair looking blue. 

How Often To Use Blue Shampoo

If you go on Youtube or Tiktok you’ll find tons of videos of people who have inadvertently dyed their hair blue while trying to use a blue shampoo.

And while this is rare, it can happen if you use blue shampoo too often. 

If you have dark brown or brunette-toned hair I’d suggest using a blue shampoo only 2-3 times a week.

And if you have light, bleached blonde hair then reduce this number to just once a week.

There is a greater chance of blue pigment being deposited on lighter hair shades.

Also blonde-haired folks can try using a regular shampoo and going for a blue conditioner instead. This will reduce the amount of blue pigment that’s deposited on hair. 

Is Blue Shampoo Bad For Your Hair

No blue shampoos aren’t bad for your hair. However, you need to be careful to select the right blue shampoo for your hair.

Just like with regular shampoos try avoiding blue shampoos with harsh surfactant ingredients like sodium laureth sulfate and sodium lauryl sulfate. 

It can be hard to find blue shampoos or other toning shampoos that are sulfate-free as they are created to be strong enough to remove brassy or yellow undertones from hair. 

But there are a few milder ones in the market, my favorite one being the Aveda Blue Malva Shampoo which is SLS and SLES-free. It also uses Malva extracts for the blue pigments and not artificial dye, so that is also a plus in my opinion. 

FAQs About Blue Shampoos

If you have any more queries about blue shampoos and how to use them on your brown/bleached, brassy hair, here are some frequently asked questions that I’ve tried answering for your benefit. Take a look!

What is the best blue shampoo for my hair?

If you have brown hair and want to remove the warm undertones then I recommend using the John Frieda Blue Crush Blue Shampoo for Brunettes. It not only removes warm undertones to give you a cooler brunette hair color but also leaves tresses shiny. However, if you want to remove orange, brassy tones from blonde hair then go for Joico Color Balance Blue Shampoo instead. 

How long should you leave blue shampoo in your hair?

You should leave blue shampoos on hair for enough time to let the blue color pigments penetrate hair strands. I suggest leaving it anywhere between 5-10 minutes depending on the porosity of your hair. 

How long does it take blue shampoo to work?

When you’re using the shampoo, you should leave it on for 5-10 minutes before rinsing it. But the effect of the blue shampoo should be almost instantaneous. However, if you have really stubborn brassiness you should use the blue shampoo for at least 6-8 weeks to get rid of brassiness completely. 

Does blue shampoo take out orange?

Yes, blue shampoos helps fix orange tones in hair as it contains blue-colored pigments. These pigments can neutralize orange tones as they are opposite in the color wheel. 

Can I use regular conditioner after blue shampoo?

Yes, you can totally use a regular conditioner after using a blue shampoo depending on your hair’s needs. But if you want to tone your hair twice over, you should try using a blue conditioner along with the blue conditioner. Look for one that is free of silicones and matches your hair’s moisturization needs. 

Final Thoughts About Using Blue Shampoos

Blue shampoos come in handy if you want to reduce warm undertones from either bleached blonde hair or brunette hair.

Using a blue shampoo can get rid of orangish undertones on bleached hair, leaving it a bright shade of platinum. 

On brown hair, blue shampoos reduce reddish undertones giving you a cool brunette hair color.

These shampoos are often confused with purple shampoos but the two have different purposes. 

A purple shampoo is used to remove yellow undertones from hair. 

You can also use a blue hair toner instead of blue shampoos but hair toners are generally stronger in pigments compared to shampoos so I don’t advise doing it at home, especially if you just want to neutralize warm tones from hair.
