When you tone your hair, you’re converting the yellow to blue. This means that if your hair is yellow, it will become less yellow after toning with Wella T18 (or any other blue-based color).
The only reason the toner doesn’t completely convert all of the yellowness to bluish tones is that the toner particles don’t stay around long enough to convert the yellow ultimately.
Toners are semi-permanent, meaning they only last a certain amount of time. Wella T18’s lightfastness is 8-12 hours.
This means that once you’ve washed your hair and applied the toner, it will fade/wash out within a day (8-12 hours).
So, the only reason your hair is still yellow is that the toner has faded and is no longer there to convert more of your yellowing pigments.
Reasons Why is My Hair Still Yellow after Toning it with Wella T-18?
Wella t18 toner is specially formulated to correct unwanted yellow tones in blond hair. It has a violet base that neutralizes the unwanted yellow shades, thus creating the purest, most radiant silver color.
As there are many ways to take care of your blonde/bleached hair, and some people might not use the product on their hair the way it is supposed to, here are some possible reasons why your hair might not be lightened even after the application of Wella t18 Toner.
Frequently Asked Questions
The color of your hair will depend on many things including the dye you used previously, how much dye was applied at the time, and what other processes have been done to your hair. It can take several applications to neutralize the yellow fully, as each time you dye, it becomes harder to remove. As a result of the previous dyes, your hair has been exposed to chemical damage. This can make it more porous and easier for color molecules to attach themselves. You must consider having a balancing treatment done first to help re-enforce your hair cuticle, then undertake a few more dye jobs. Remember that some people have more resistant hair than others, so it can take longer to get your desired results.
First of all, you need to do a balancing treatment on your hair. It is essential because you are trying to re-enforce the cuticle, making it easier for other dyes to adhere to the surface of the fiber, thus allowing them to release more easily later on. Your stylist can recommend a good one, and you can then go on to do your color, but it’s best to leave the toner for an hour or two before doing this as we want all the chemical processes to calm down first.
When doing the balancing treatment, there is a window of about 30 minutes when your hair changes from being porous enough for other dyes to attach themselves to the fiber, but before it starts to re-enforce the cuticle. If you use your processing time too soon, other unwanted dyes can attach themselves. By leaving your color for a while before doing the balancing treatment, any previous dye not correctly removed will have had enough time to detach itself from the fiber and be disposed of via your washing and rinsing processes. This means that when you go to put on your new color, it will be able to attach itself solidly and not interfere with your new dye at all.
Very often, hair that seems to be porous is actually in good condition when it comes to the cuticle. For example, you can have split ends or frizzy hair, but underneath the surface is very strong and healthy. This means that your hair appears to be brilliant at absorbing color, but in fact, it’s just bouncing it off! If you want to achieve good lasting hair color, then you need to consider strengtheners or treatments. This will help to reinforce the cuticle so that when color molecules attach themselves, they are more likely to stay put.
If your hair is still very yellow after a Wella Color Charm T18 1N toner treatment, you may need to consider doing more treatments. Please note that this product will not do anything to alleviate previously dyed brassy or warm tones in the hair. This means that if you have used another color before this, especially a warmer tone, you may still have yellow undertones coming through.
