Ash cancels the yellow. But make sure to only apply the ash product on the hair that you bleached that are yellow. The ends of your hair are usually much light and will absorb the ash color much quicker than the roots.
When deciding how to tone yellow hair to ash, try using a violet shampoo first. As purple is the opposite of yellow on the colour spectrum, the shampoo's purple pigment draws out the yellow brassiness from your blonde, neutralises those unwanted tones, and makes your colour look cooler, healthier and more vibrant.
Yes, using a light ash blonde can help neutralize the orange tones in bleached hair. The ash tones in the dye contain green and blue pigments, which can counteract the warm, brassy orange hues. Here are some steps you can follow:
Red tones work great over yellow or darker hair in my experience. I also had pink hair that wasn't bleached very light, it faded to a coral color, so that would probably be a good bet as well. Just keep in mind that pastels need very light hair to work, so darker color is better.
Green (also known as ash) is the opposite to red. Use green and ash to cancel red. These mix tones are best combined with base colors to achieve the hair color results that you desire. However, instead of using pure colors to neutralize, you can also use pre-mixed toners.

Orange hair to light brown: Try using a medium ash blonde hair dye, as it can help neutralize the orange tone and achieve a cool light brown hue. Another option is to wait for the orange tones to fade and apply a light brown hair dye over it, making sure to choose a shade with ash undertones to neutralize the orange.
PURPLE/VIOLET PRODUCTS
They allow you to stay in control of any yellow tones that might appear without drastically changing your hair colour.
Get your hair to a level 9/10, which is light blonde.
Most people don't have hair that's a level 9 or 10, so you'll probably need to bleach it. Check to see how many shades lighter your hair needs to be, if any. You can do a quick online search to find a chart that will show you the different hair color levels.
To recap on the chemistry of bleach, you'll remember that when the hair is lightened, the pigment is stripped to reveal natural underlying yellow hues. Most hair just simply doesn't lift past this stage to a white colour.
And because those UV rays are stronger in summer compared to other times of the year, some strands will turn a copper red colour due to the underlying warmer tones in your brunette hair being revealed as it's bleached by the light. Suffice it to say, until new hair grows through, the reddish tint will remain.
Taking the next step in the laws of neutralization, you can conclude that a violet toner or blue violet color formula will cancel out the unwanted yellow or gold tones in your blonde hair color; blue will cancel out the unwanted orange or brassy tones in your brown hair color, which is where products like blue shampoo ...
Even though ash blonde might seem like a light and delicate color, it will indeed cancel out brassy tones and orange hues commonly left behind by hair lightener and other hair color.
The underlying pigments in your natural hair colour can influence the final result of hair dye. If the ash blonde dye doesn't fully neutralize the warm undertones in your hair, the colour may shift towards yellow as it fades.
Application of Brilliant Blonde purple shampoo
The shampoo contains purple pigments, and so will help to regularise the whole head, getting rid of any remaining yellow. And help you to get to a truly consistent ash blonde. Leave in the shampoo for a couple of minutes.
Purple shampoo
Like blue shampoo, purple shampoo is another at-home option with color pigments formulated to counteract brassy yellow tones in color-treated hair. It's primarily used to tone lighter hair colors, such as platinum blonde or silvery gray.
Ash blonde is close to grey in colour. Your clothing and make-up should include bright colours to bring more vibrancy to your style so that the overall look does not appear too dull.
For warmer undertones (think hints of yellow or orange), your ideal hair color should give your skin a healthy, natural-looking flush. Go for hair colors that are cool, ashy, or have reddish tones, like honey or strawberry blonde hair, golden copper, cool beige brunette, and rich golden brown.
Your stylist's colour-correction methods may vary, but it's likely they'll reapply bleach to lighten your hair to fully remove the orange, then tone your hair with an ash or light beige colour to neutralise brassiness.
If you have any orange left in your hair, T14 is probably the best for your hair over T18. T18 is only effective if your hair is a level 10 or higher (purely yellow). Putting the wrong toner in your hair won't necessarily harm it, but it likely won't affect the color at all.
If your hair turned yellow after bleaching, you can apply the following on your hair: the red petals of hibiscus, purple shampoo, henna, and apple cider vinegar. Then, you can prevent that brassy tone from returning by making some changes to your hair care routine.
Select a cool haircolor, like one with the word “ash” in the name, since it's less likely to turn brassy than one that's warm.
