Add Cool Tones: Cool tones counter-balance and reduce unwanted warmth. You can add cool tones by applying a toner or demi-permanent colour. If you want to reduce warmth without adding any depth, we recommend selecting a toner or demi-permanent colour which is lighter than the lightest colour level in your hair.
use an anti brass or ash (containing some green) color depositing conditioner to cancel out the warmth! -hairstylist :)
To achieve a cool shade, you should use a blue shampoo over a warm hair base. What does blue shampoo do? Blue cancels out orange tones and gives you a cool base for further color applications.
Look for a toner or a tinted shampoo that's tagged with ``ash'' because these products are specifically designed to counteract the warmth in your hair. Any product with a violet or blue base will act as a color corrector, effectively muting the redness without a total color overhaul.
``Experts advise waiting at least 2 weeks (technically 15 days) before dyeing it again. However, this is the minimum amount of time and, in some cases, you may need to extend that period to 4 weeks.
How soon can you dye your hair again? Wait at least two weeks after your last dye session before coloring your hair again. For maintaining your color, stylists suggest visiting the salon every four to six weeks for touch-ups.
Just as a purple shampoo neutralises brassy tones on blondes, using a blue shampoo on brown hair neutralises orange and red tones for brunettes.
Make sure you get washed immediately after you notice you have over-toned those locks! Most toners are not permanent, therefore eventually, after several washes, the 'cool' tones will fade. If you want that toner gone quicker, 2-3 washes with a clarifying shampoo will start to remove the blue, grey or purple stains.
If your hair is brown, you may need to bleach it more than once before you apply the grey dye. It's important you get your hair as light as possible before you attempt to turn it grey – this will help ensure a more even tone and vibrant, all-over colour.
Use a purple or blue shampoo
Pick your toning shampoo based on the original colour of your hair before you applied the bleach. Blue and purple shampoos neutralise unwanted brassy tones to reveal a cooler blonde or light brown shade.
Dishwashing Soap – Dishwashing soap is also a gentle way to remove color. In fact, you can substitute this type of soapy liquid for the shampoo and use it with your vitamin C tablets or alone. Either way, it works well for semi-permanent color mistakes.
Hair lighteners or toners are great for lifting darker shades and achieving a lighter shade. Apply the toner or hair lightener to your hair according to the product's instructions. Rinse it out once you've reached your desired color. Finish with a deep conditioner to replenish your hair's moisture.

Highlighted hair is often porous and can take on ash tones heavily – the hair then appears greyish or sometimes even silver. When you say your blonde highlights look grey, it is often because they take on a grey-blue tone, sometimes all over and sometimes in patches.
Q: For folks who don't want ashy hair color, is it hard to fix? A: It's super easy to fix. When formulating your shade, your colorist will likely use a copper or golden tone to counteract the ash.
This is because it can strip the toner out of the hair! Instead, wait until your toner has faded completely before fixing any brassy tones with a purple shampoo.
Washing your hair with any shampoo — whether traditional or clarifying — will cause color-treated to fade. Although clarifying shampoo can remove color through repeated use, it isn't specifically designed for that purpose.
WHAT DOES BLUE SHAMPOO DO TO BROWN HAIR AND HOW DOES IT HELP PREVENT BRASSINESS? It all goes back to the basic principles of the color wheel; blue and green fall directly opposite from red and orange, which means that the cooler blue and green tones will neutralize and counteract the warmer ones, says Dupuis.
There are countless shades of dark brown, from rich mahogany to warm caramel, and the specific tint of brown will depend on how much red, yellow, or blue you use. To add warmth to your dark brown, add more yellow; to make it cooler, add more blue.
Generally speaking though, it's best to wait 4-6 weeks before having another color treatment – in most cases, this is enough anyway and reduces the risk of hair damage. There are some exceptions, but in general, it's better to err on the side of caution and wait for this long.
Your color correction can be done immediately or after a few weeks depending on your current hue. Every stylist uses different formulas and techniques, however, and only they would be able to know the best time to do a color correction.
