The first step in toning your curls is to determine which toner will give you the results you’re looking for. Unfortunately, choosing the right one can be nearly impossible with all of the toner shades out there.

Many have trouble choosing between mega-popular Wella Color Charm toners, Wella T14 and T18. They wonder what makes them different and which one they should choose.

If you have these questions, you’re in the right place. This article will tell you everything you need to know about both Wella toners and their differences, so you can easily choose between the two and achieve flawless color results! 

What’s Wella T14? 

Wella T14 (Pale Ash Blonde) is a permanent liquid toner that counteracts orange/gold tones and leaves you with a silvery ashy blonde color.

The toner’s base is a mix of violet and blue, which gives it the ability to cancel out the brassiness of bleached hair.

It should be mixed with a 10 or 20 volume developer for it to work. According to the packaging instructions, you can leave the toner on your hair for up to 30 minutes. It’s a great choice for anyone who wants a beautiful cool-toned blonde.

What’s Wella T18? 

Wella T18 (Lightest Ash Blonde) is similar to T14 because it’s a permanent liquid toner in the ash blonde family. The toner’s base is violet, enabling it to cancel out or reduce yellow tones that are common after bleaching the hair.

People worldwide use it to turn their yellow, brassy hair into a perfect ash blonde hair color. Just like with Wella T14, T18 should be mixed with a 10 or 20 volume developer and rinsed out after a max of 30 minutes.

Wella T14 vs T18: Key Differences


Now that you’ve got a bit of background on both Wella T14 and T18, let’s dig a little deeper. This section will illuminate the differences between both toners in detail: 

  • The color results – While T14 Wella toner gives you a pale ash blonde result, T18 Wella toner gives you a light ash blonde result. 
    • This means: 
      • If you choose T14, the color result will be considerably lighter than if you went for T18. 
      • T14 has silvery tones that you won’t get with T18. 
      • Since T18 has a violet base, it’ll leave a violet undertone to your strands. 
      • T14, which has a blue base, will be much more gray/silver than violet. 
  • When they should be used – T14 should be used when you have unwanted orange/gold, brassy tones in your hair and want an ashy blonde result. T18, on the other hand, is best for when your hair has unwanted yellow tones, and you want a super light ash blonde or a platinum blonde.

Can You Use Both T14 and T18?

Since Wella T14 is best for neutralizing orange/gold tones and T18 is best for neutralizing yellow tones, many wonder whether they can use both if they have unwanted yellow and orange tones following a bleaching session.

Technically, you can mix both toners to get rid of yellow and orange tones in your hair, though professionals do not recommend doing so at home.

But if you insist on doing it, be careful to adjust the amount of developer you use to ensure that the developer-to-toner ratios are correct. Also, it’s important to consider how much of your hair is yellow versus orange/gold.

If most of your hair is orange, you should use more T14 than T18 and vice versa. If your hair is mostly yellow, you should use more T18 than T14. If your hair is equally yellow and orange, use half T14 and half T18. 

You can apply the mixed toners all over your hair or apply each toner individually on specific areas – T14 on the orange bits and T18 on the yellow parts.

Just know that while you won’t have any yellow or orange tones left in your hair, you will end up with different shades of ash blonde throughout your hair.

Mixing two toners can come with uncertain results, especially if your hair has not been lightened to the appropriate level before applying it. For this reason, we recommend that you consult a professional to prevent a hair disaster.

Otherwise, the possibility of unintentionally ending up with purple hair or orange hair is very real. If you do a quick YouTube search, I’m sure you’ll find several videos describing hair coloring disasters where the hair turned an undesirable color.

How to Get the Best Possible Toning Results 

In the middle of a city, there is a gorgeous blonde-haired girl walking down the street with a nose ring, pink lipstick, and a great smile.

You should follow the toner instructions and then tweak the process according to your hair for the best toning results. You’ll need to mix the toner according to the instructions on the packaging – this part should never be tweaked.

Apply the toner first to the yellowest or orangest parts of your hair, and then apply it to the rest of your hair. Allow the toner to process for about 10 minutes, and then check a section of hair to see if it is the color you want.

If not, reapply the toner to that section and allow it to process further, checking now and again to see the results. Don’t allow the toner to process for longer than 30 minutes, as over-toned hair is an absolute nightmare. 

Here are some expert tips to help you get your desired result: 

  1. Make sure that your hair is light enough for the toner. For both T14 and T18, your hair should be lightened to a level 9 or lighter. If it is too dark, you won’t notice a difference after processing. 
  2. Use a 20-volume developer for long-lasting results. If you use 10 volume developer, you’ll only get a semi-permanent result, and your toner will fade quickly with every wash. 
  3. Pay careful attention to your natural hair when choosing a toner shade. This will help you avoid ineffective toning sessions or disastrous results. Look at a color wheel, note the color you’d like to neutralize (orange, yellow, etc.), and then note the color directly across from it on the color wheel – that should be the color of your toner’s base. Hint: blue cancels out orange, violet cancels out yellow, and green cancels out red
  4. Reach out for help when needed – Toning will not always be as straightforward as you may think. If you run into issues, don’t hesitate to reach out to a professional colorist for advice. It may just help you avoid a costly trip to the salon for a color correction service.
  5. Keep a timer – You may be surprised at how quickly time flies as your toner is processing – you really don’t want to leave it on for too long. 
  6. Saturate your strands – To prevent a patchy result, take the time to fully saturate your hair with the toner. If your result is patchy, you may have a hard time fixing it. 
  7. Consider a porosity equalizer – Harsh bleaching sessions could leave your hair more porous in some areas than in others. This can lead to a super patchy toning result. A porosity equalizer can even out your hair’s porosity before applying the toner, enabling you to get an even toning result.
