How to use Wella T18 toner on brown hair, the results before and after

using toner and bleach

First and foremost, I want to show you the before and after of using Wella T18 toner in my hair that was brown. 


Have you bleached your brown hair and you have ended up with some scary, chicken yellow streaks, that make it so you don’t want to leave your house?


Don’t worry, the same thing happened to me when I bleached my brown hair for the first time to go to a platinum blonde.

Except that I was ready to counteract those horrible chucks in my hair hair.

I had Wella T18 toner on my hands.

And it really was my salvation.


That’s why, if you are about to bleach your brown hair, don’t let my advice pass you by: have Wella T18 toner at the ready.

Because it will do magic with the color that you want to get after bleaching.


 If it is the first time that you are going to bleach your hair, I’m sure you think that after putting up with the unbearable smell of the bleach, the magic will happen by itself.  

But let me tell you something: It’s a complete lie.


If you go from a natural brown in your hair, the bleach strips out those natural pigments of your hair.

And in this process, I went through various colors.


You’ll see that your brown hair will go from red, to orange and finally yellow.

But that yellow has nothing do to with the color that I’m sure you imagined in your dreams.


 It will end up an orange or yellow that isn’t ashy or platinum or anything. But what it is, definitely, is a scary color. 

And that’s where Wella T18 enters into the game.


Because it will give your hair a platinum yellow color that you were looking for.

You don’t believe me? Do you still think that with bleaching alone, you’ll get the results you dreamed of?


Well, I can’t force anyone to believe me. But as they say, “Let the dogs bark, Sancho, it’s a sign we are moving forward.”

And most of the women that bleach their brown hair to get to platinum blonde use this toner. There’s got to be a reason why, right?

I knew I would spark your interest. That means you are an intelligent woman.


That’s why, today, I’ll tell you:

  • What is Toner Wella T18
  • How to apply the toner in your hair
  • How often to apply the toner
  • How to care for your toned hair



What is WellaT18 toner?

brown and dark hair

Wella T18 toner is a product made to neutralize yellow or orange tones that end up in your bleached hair.

It’s practically a miracle in a bottle, which will give your hair a natural look instead of a processed look.


The toner contains ammonia, which is mixed with other chemical products to create a gel consistency. When this gel is applied to your hair, it picks up and lightly tones specifically blonde tones that are delicate.

Normally, these toners are colored like violet, blue and green.


 These colors are what end up canceling out the yellow, orange, and red tones that are present in your bleached hair.  


It is important that you understand color theory when you tone your hair so that you get the desired result.

Since Wella T18 toner is violet, it neutralizes the chicken yellow of your bleached hair.

That’s why, if you want to go to platinum blonde, you should cancel out those yellow tones with this toner because it is the opposite of yellow on the color wheel, and therefore, they cancel each other out.

Why can’t you get to platinum blonde with just bleaching?


Because the bleaching mixture eliminates the pigments of the hair, but depending on the weight of the molecules that make up that pigment, some colors disappear quicker than others.

Another important piece of information is choosing the peroxide correctly.

I recommend that you use this toner with a 20-volume peroxide.

Do you want to know why?


Because 20-volume peroxide has its own lightening effect.

If you have bleached your hair and you are prepared to tone it to get to an ashy or platinum blonde, a less-volume peroxide will do the trick.


How to apply the toner

Before applying the toner in your hair, I suggest that you prepare all the elements that you need.


The elements necessary to apply toner:

  • Toner
  • 20-volume peroxide
  • Gloves
  • Brush or dye brush
  • Glass bowl, never use a metallic one
  • Aluminum foil


Applying the toner

  • In the glass recipient, mix one part toner with two parts peroxide.
  • As you mix it, you’ll realize that it forms a thick gel.
  • I advise you to do a spot test to determine the processing time. For this, choose a chunk of hair that isn’t really visible. Apply the toner and watch how long it takes to get the desired results.
  • Separate your hair into pieces and apply the toner. Try to work as fast as possible. Generally, I start with the layers around my face and neck and leave the roots for last because they absorb the toner in less time.
  • You will see the toner start to turn a deep tone between blue and purple. Don’t freak out! It’s time to let the miracle happen.
  • Let the toner sit for between eight and ten minutes to get a lighter tone and between twenty to twenty-five minutes to get a darker tone.
  • Once the time has passed that you think is best for you, it’s time to rinse the hair. Rinse carefully, because if you don’t get all of the product out, you run the risk that the toner will keep working, and they only thing you’ll get is unnecessary damage to your hair.

It’s very important that you deep condition your hair.

Because you can’t forget that just as much in the bleaching as in the toning, we have used chemical products that strip and weaken our hair.

In my case, after rinsing the toner, I applied a coconut oil mask and let it sit for an hour.

Even though it seems like a lie, when I dried my hair, it looked amazing, free of yellow-streaks, thanks to the toner, and healthy.


How often to use toner

Keep your blonde hair free of yellow streaks is not easy, but it also isn’t impossible.

Blonde hair turns yellow when the dye oxidizes. As we say, the toner cancels out these unwanted colors upon depositing the pigment into the hair, but eventually it fades.


  • How often to tone your hair will depend on a few variables.
  • For example, your hair care routine.
  • Use sulfate-free shampoos and avoid pools, because chlorine oxidizes the color faster.
  • Once a week, use a toning shampoo, to extend the effects of the toner. I recommend that you don’t abuse it, because it tends to dry out your hair a lot. Once a week is more than enough.
  • And if you can, avoid washing your hair more than three times a week. If you feel your hair is very greasy, try a dry shampoo.
  • With this product, you avoid using water, which is what erases the effect of the toner.
  • In my case, I toned y hair once a month.


Now, you can use toner calmly so that you hair looks healthy and naturally blonde, like mine.
