  • To get rid of the blue tint in hair, you have to know why they appeared there.
  • If you have been coloring your hair with an ashy hair dye for a long time, you should switch to one with copper undertones. They’re usually identified by a .4 in the coloring kits.
  • If the blue tint appeared in your hair because you applied a toner, you could wait for it to fade after two weeks or wash your hair with a clarifying shampoo.
  • And if you have blue hair after using a toning shampoo, you have obviously used it too often. Then, only stop using it.

Suddenly, one day you look in the mirror, and you discover that your hair is a shade of blue. Of course, you weren’t looking for it, and it seems to invite you to become part of the Smurfs’ family.

Do you remember them?


I still smile when I remember the friendliness of these funny blue gnomes.

Did you know that there is a Smurf village in Spain?


Well, actually the name of the village is Júzcar. Due to marketing reasons, the name of the famous characters was used after two Smurf’s movies were filmed near that Andalusian village.


Leaving the Smurfs aside and going back to the blue tint in your hair, how did it appear there?

If you’re looking to get rid of it today, you weren’t planning to get it, were you?


Basically,  the blue tint appeared because, believe it or not, your hair has memory. 

Your hair has memory in both its most superficial and innermost layers.


Therefore, every time you apply hair color, the hair memorizes it.

The same happens with toner, shampoo, and every treatment you apply to your hair.

However, in the case of colorimetry, it’s about pigments.  And if a blue tint appears in your hair, it means that some residual product pigments are taking center stage. 


In short, the blue tint came to your hair because of a previous blue hair dye, toner, or shampoo.

But don’t worry because the solution is easier than you think. Today, I’ll explain the solution.


 What you shouldn’t do is use a color remover or apply bleach. Otherwise, you’ll only ruin your hair. 


If you use a color remover, you’ll remove the blue tint. But, you’ll also remove all the artificial pigments from the hair.

Moreover, if you apply bleach, the blue tint will be gone together with the natural and artificial pigments in your hair.

Of course, your hair will be brittle, and you’ll have to think about applying a hair dye or toner.


Getting rid of blue tint is easier than you think. Today, you’ll find out how to do it.

To remove the blue tint left behind by an ashy hair dye, you’ll need to use a hair dye with copper undertones

some hairdressers hate box dyes

If your base color is dark brown 3, brown 4, and light brown 5, you have orange undertones that can only be neutralized with ash hair dyes.


I’m sure that, at first, everything was fine, and you were more than happy to have hair without strident orange tones.

 However, applying several ashy hair dyes results in a buildup of blue pigments in the hair. They’re hidden until they decide to explode. 

What’s the solution?


Replace the ashy hair dye with another one that ends with 4 because it means it has copper undertones.

If you have dark ash blonde 6.1, ash blonde 7.1, light blonde 8.1, or very light ash blonde 9.1, you should choose the same color level but with an orange or copper undertone 4.


This way, your new color will be:

  • Coppery dark blonde 6.4
  • Copper blonde 7.4
  • Light copper blonde 8.4
  • Very light coppery blonde 9.4


It’s simple!

You keep the level of your blonde and only change the orange undertone that neutralizes the blue tint.

Does any hair color brand offer these shades?


 Yes, you can choose the one you like the most, for example, L’Oréal, Koleston, Garnier, or Wella. 

Any of these hair dyes with copper undertones will cover bluish tint perfectly.


Now, if a hair dye is not the reason for the blue tint in your hair, you may have used another product.


If a blue tint appears after applying toner, you can quickly remove it with a clarifying shampoo

washing removes color

Toner is frequently used in salons after bleaching or coloring to remove unwanted orange tones. It’s because orange and blue are opposite colors on the color wheel.


So, you most likely used a blue toner to remove the orange.

 Toner can be a bit tricky to handle and many things can go wrong. 


For example, if you leave the toner on longer than indicated, or if the toner contains blue pigments that are too intense, some complications may arise. For example, your hair may turn blue.

You have two ways to go:

  • If you’re patient and the blue tints are very faint, wait for the toner to disappear. I can assure you that it will after a few washes.
  • If  the blue tints keep you from sleeping, or if you only dream of Smurfs, use a clarifying anti-residue shampoo twice a week. 


It’s specifically designed to remove any chemical pigment or serum residue you may have applied. As you have a slight blue tint, it’s considered a pigment residue.

That’s why this type of shampoo works.


The most commonly used ones?

  • Neutrogena Anti-Residue Clarifying Shampoo
  • Biolage Normalizing Clean Reset Shampoo
  • Paul Mitchell Shampoo Three


You’ll only need to wash your hair twice a week with any of these shampoos to remove the blue pigmentation residue. Your hair will be ashy without the orange tones you removed with the toner.

Now, it’s the turn of those who overdid it with the use of blue shampoo.


If you abused the blue shampoo and your hair has a blue tint, stop using it

dark pigments

If you neutralize your orange tones with blue shampoo, you may get a slightly blue tint.

Don’t worry because the solution is at your fingertips. Why?


 The blue shampoo only coats the surface of the hair. So, the moment you stop using it, you won’t deposit blue pigments anymore. Also, the ones you have will disappear with washes. 

And if you want to further accelerate the fading of the blue tint, you can use a shampoo with sulfates that fade the color.


Chances are that those blue tones will have disappeared after three or four washes.

Of course, after you get rid of the blue tint, do an intensive moisturizing treatment because sulfates dehydrate the hair and turn it dry and dull.



If a blue tint appeared in your hair after using an ashy hair dye, a blue toner, or if you abused the use of blue shampoo, you know how to fix it.

Remember not to go for aggressive processes such as bleaching or color removers. They won’t remove the blue tint and, moreover, they can change your hair color.
