All brunette hair isn’t all the same. There are different shades when it comes to dark hair just like with blondes.
Some hair has reddish undertones and can appear auburn in the right light.
Also, if you’re out in the sun a lot, then your brown hair color can develop brassy undertones giving it a warmer hue.
These look great too, but if you prefer your brunette hair with cooler undertones, then you can simply get rid of this brassiness to make it look more ashen.
In this article, I’ve described the ways to tone brown hair to ash easily.

How To Tone Brown Hair To Ash
Want to get turn your dark brown or reddish-brown hair to that perfect shade of ash? Here’s how you can do it. Read on to know!
How To Tone Brown Hair To Ash Using The Color Wheel
Before we get to learn how to tone brown hair to ash, we need to understand the color wheel theory.
There are a group of colors called complementary colors that are directly opposite one another in the color wheel.
One of these shades can cancel out the other color.
The most prevalent example of this is purple shampoos.
Since purple is directly opposite to yellow in the color wheel purple shampoos are used to cancel out yellowness in blonde hair to give it a platinum hue.
Similarly, if you want to tone brown hair to ash, you’ll need to cancel out the shades of red and orange in your hair.
Blue is the color that is opposite to orange in the color wheel, so if your hair has brassy notes, then a blue-tinted toner or shampoo can help.
But if you’re hair has is a more reddish/auburn shade then you can try green as it’s the color that is complementary to red in the color wheel.
Use A Hair Toner
If you have natural brunette hair or have colored your hair a brown shade and want to make it a bit ashier, then you can a hair toner.
A hair toner is not a hair dye, it doesn’t alter the color of your tresses. It simply adds pigments to your hair, so that certain hues get canceled out.
Toners are generally used after a hair coloring session to make your locks the right shade of blonde or brunette.
You might have heard of purple toners or blue toners that are used after bleaching to remove brassy undertones from blonde hair.
But hair toners come in all shades! There are blue toners and green hair toners as well.
As I’ve discussed in the section about the color wheel, you can cancel out the reddish undertones in your brunette hair by using a green toner and orange tones by using blue.
In fact, a lot of hair toners double as conditioners and masks and come with several nourishing ingredients.
So you can go for these if you’re brunette hair seems dry or damaged.
Some of my favorite hair toners that tone brown hair to ash are given below:
Matrix Color Results Brass Off Hair Toner
Pravana Chromasilk Blue Hair Toner
Try a Blue Shampoo
I have naturally dark brown hair and want to keep it looking ashy. So sometimes, it’s not convenient to use hair toner.
So if you want this ash brown shade on a regular basis, you should try investing in a blue shampoo.
A blue shampoo is just like a regular shampoo but it contains a lot of blue pigments.
These pigments help neutralize orange tones in your hair and leave it ashy and cool.
And you don’t have to spend time leaving it on like you would a hair toner.
Redken Color Extend Brownlights Blue Shampoo
But I have to warn you, it’s not advisable to use blue shampoos more than once a week.
This can cause a lot of blue-pigment build-ups and might stain your scalp.
Also, using this shampoo regularly might cause your ashy strands to actually turn blue with time.
Another thing to remember is that just like with other shampoos, these blue ones also have sulfate-based and sulfate-free variants.
If you have dry, damaged, or chemically-processed hair, I’d recommend you go for the sulfate-free ones I’ve listed below.
You should also go for sulfate-free shampoos if you’re toning color-treated hair as harsh surfactants can strip hair dye.

Apply A Temporary Hair Dye
If you’re using a blue hair toner to tone brown hair to ash, then the results might last anywhere between 4-6 washes.
So it’s definitely not a long-term solution.
And with blue shampoos, there’s the risk of staining.
The best solution in this case? Try a temporary hair dye.
Don’t worry, you’ll need a hair dye that will replace the reddish undertones in your brown hair with ashy undertones. So you won’t require a strong chemical dye.
But you need to be careful as to the shade you choose.
If you’ve noticed, a lot of hair dyes come marked with a number.
This is because of something called colorimetry, where each color is assigned a number between one to ten. Here, number 1 represents black hair and number 10 represents light, platinum blonde hair.
Brown hair falls somewhere in the middle with level 3 representing dark brown, level 4 representing medium brown, and 5 being light brown.
But most shades are marked 4.5, 4.2, 6.5, and stuff like that. So what’s up with the number after the dots?
Ah! Now that’s the crux of the matter. The numbers after the periods represent the undertones in hair coloring.
And ashy undertones are marked with the number 2.

So for the best results, you should go for an ash brown hair dye that is at the same level as your natural (or base) hair color.
Example: If you have dark brown (level 3) hair, you should go for ash brown hair dyes marked 3.2. And if you have light brown (level 5) hair, get ash-brown hair dyes in 5.2.
Of course, you can always choose to make your hair appear lighter or darker that is upto you.
But if your only goal is to minimize the reddish highlights in your brown hair then following this method is a good idea.
