Will Wella T18 work on yellow hair?

Wella T18 (also known as Wella Color Charm T18 or Wella Toner T18) is a hair toner that is specifically formulated to remove yellow and orange tones from bleached hair.

So, the answer to the question, “Will Wella T18 work on yellow hair?” is a resounding yes! Wella T18 is a toner that is designed to remove unwanted yellow hues from blonde hair, so it would be an ideal choice for those with yellow hair.

If you have yellow hair and want to remove the yellow tones, Wella T18 can be an effective option. However,  keep in mind that hair toners are typically used on hair that has already been bleached, and may not work as well on natural hair that has not been lightened.

Wella T18 is a semi-permanent toner, meaning that it only works to reduce the intensity of yellow hues in the hair and does not completely remove them. So, those with yellow hair may not see a dramatic difference in color, but they can expect to see a subtle hint of cooler shades in the hair.

It is important to note that Wella T18 may not work for all yellow tones. It is best suited for yellow tones that are light to medium in intensity. Additionally, it is also not ideal for yellow hues that are darker in tone. In this case, a different toner or hair color may be a better choice. Additionally, it is always a good idea to perform a patch test before using any new hair product, especially one that is intended to alter the color of your hair. This will help ensure that you get the desired results and avoid any potential adverse reactions.

Why Does Blonde Hair Turn Yellow?

When hair is lightened, a pale yellow pigment is often revealed and “controlled” through the use of a gloss or in-salon treatment. If you go too long between coloring appointments, your hair may start to turn yellow. Using a hair lightener can result in a yellow hue ranging from an orange-tinged level 7 to a very pale level 10.To maintain the desired color between appointments, you can use a shampoo for color-treated hair, and incorporate purple shampoo into your hair care routine. These measures will help maintain the gloss and prevent the yellow tones from becoming more pronounced.

The second cause is fading or brassiness in blond hair, which may occur if proper color care is not maintained or if heat styling is done frequently without protection. In both cases, the yellow tones can be corrected with the use of a toner.

Other environmental factors that causes your hair can turn yellow include:

  1. Exposure to the sun: UV rays from the sun can cause hair to become yellow or brassy over time, especially in blond or light-colored hair.
  2. Chlorine in swimming pools: Chlorine is a chemical commonly found in swimming pools and it can cause hair to turn yellow or green. This is especially true for blond or light-colored hair.
  3. Hard water: Hard water contains minerals such as calcium and magnesium, which can build up on the hair and cause it to become yellow or brassy.
  4. Using the wrong hair care products: Some hair care products, such as shampoos and conditioners, can contain sulfates or other harsh ingredients that can cause hair to become yellow or brassy over time.
  5. Age: As we age, the natural pigment in our hair starts to fade, which can cause hair to become yellow or gray.
  6. Using heat styling tools: Frequent use of heat styling tools, such as curling irons and hair dryers, can cause hair to become damaged and yellow over time.
  7. Smoking: Smoking can cause hair to become yellow or brassy due to the chemicals found in tobacco smoke.
  8. Medical conditions: Certain medical conditions, such as an overactive thyroid, can cause hair to become yellow or brassy.

To protect your hair from these factors, you can wear a hat to prevent sun damage and use a swim cap when swimming. You should also be aware that the water in your shower can contain minerals that can deposit on your hair, causing yellow tones. To help prevent this, you can install a water-filtering shower head to remove chemicals from your shower water.

Which color toner can be used to neutralize yellow hair?


The Wella color system uses a numbering system to indicate the depth and tone of each hue. The number following the dash represents the major tone, while the second number represents the minor tone. For example, a 9/16 color would be a light ash blonde with a major tone of ashy blonde and a minor tone of violet, which can help to neutralize yellow tones. Green tones can be added to a toning formula to give the shade more dimension and reduce red tones, while blue tones (indicated by an 8 as the major or minor tone) can help to neutralize orange tones.

In conclusion, Wella T18 can work wonders on light-medium yellow hues in the hair, but it is not the ideal choice for darker yellow tones. If you have yellow hair, it is best to consult a professional hair stylist to determine the best option for you.
