Why is my hair still yellow after toning it with wella t18.

As a beautician, I understand how frustrating it can be to spend hours toning your hair only to end up with brassy or yellow tones that will stay the same. Many clients have encountered this problem, especially after trying to tone their hair with Wella T18. 

In this blog post, I will explain why your hair may still be yellow after toning it with Wella T18 and provide actionable tips to help you achieve your desired hair color.

What is Wella T18?

Wella T18 is a toner to help neutralize and eliminate yellow tones in bleached or lightened hair. It is famous for those looking to achieve a cool, ash-blonde shade. However, despite its popularity, it is only sometimes effective for everyone.

Why is My Hair Still Yellow?

There are several reasons why your hair may still be yellow after using Wella T18. Some of the most common reasons include the following:

1. Your hair was not lightened enough: Wella T18 is most effective on hair that has been lightened to a pale yellow or almost white shade. If your hair is still too yellow or brassy, it may need to be lightened enough to achieve the desired result.
2. The toner was not left on long enough: It is important to follow the instructions carefully when using Wella T18. If the toner is not left on for the recommended amount of time, it may not be able to neutralize all of the yellow tones in your hair.
3. Your hair is too porous: Porous hair can absorb color unevenly, leading to patchy or yellow tones. If your hair is overly porous, it may be challenging to achieve the desired result with Wella T18.
4. Water quality: Hard water can cause discoloration in hair, even after toning. If you live in an area with hard water, it may be contributing to the yellow tones in your hair.

Actionable Tips:

1. Ensure that your hair is lightened enough: Before using Wella T18, make sure that your hair is lightened to a pale yellow or almost white shade. If your hair is still too yellow, you may need to bleach it again before toning.
2. Follow the instructions carefully: Be sure to follow the instructions on the Wella T18 packaging carefully, including the recommended processing time. This will ensure that the toner can work effectively.
3. Consider using a pre-toning treatment: A pre-toning treatment can help to even out porosity and prepare your hair for toning. This can help to prevent yellow or brassy tones from appearing after toning.
4. Use filtered water: If you live in an area with hard water, consider using a filter to remove minerals and impurities. This can help to prevent discoloration in your hair.

Conclusion:

Toning your hair can be a great way to achieve your desired shade, but it can also be a frustrating experience if you don’t get the desired results. Suppose your hair is still yellow after toning it with Wella T18.

In that case, it may be due to several factors, including insufficient lightening, inadequate processing time, overly porous hair, or poor water quality. However, by following the actionable tips outlined above, you can help to achieve the desired result and avoid yellow or brassy tones in your hair.

In addition to the tips mentioned above, it is also important to consider the health of your hair. Bleaching and toning can damage your hair, so using high-quality products and maintaining a healthy hair care routine are essential.

Regular conditioning treatments and avoiding excessive heat styling can help to prevent damage and maintain the vibrancy of your color.
