Another way to use them is to mix it with your shampoo or conditioner.

This will help to neutralize any brassy yellow or orange tones in your hair.

You can also it as a root touch-up.

If you have roots that are a different color than the rest of your hair, then you can cover them up. (Although it won’t give as good coverage as hair dye or permanent hair color will.)

Simply apply it to your roots and brush it through!

If you have bleached hair, you may need to use a stronger formula. Bleached hair naturally draws warmth and is the most popular reason for toning hair.

In this case, it is best to consult with a professional so that you can get the right product and the correct amount to use.

What volume hair toner do I need?

Generally speaking, you need 20 Vol if you are just refreshing colors already professionally applied, 30 Vol if your objective is to lift the color one level, and 40-50 Vol in order to take it up two levels.

It all sounds a bit daunting at first, but fear not!

The great thing about home toning products is that they usually come with detailed instructions on how to choose the volume that’s right for you.

Oh, and don’t forget to set a timer – precision is power!

How do you know when your toner is done?

The best way to determine if the process is done is by checking the color of your hair!

If it is the desired shade, then you can rinse out the toner.

If your hair color is looking too light or too dark, then you can mix in a little bit of developer to lighten or darken it.

Be sure to test the product on a small area by doing a strand test before applying it to your entire head.

How often to use hair toner?

There is no set rule for how often you should use toners to spruce up your hair color.

However, most people find that using it once or twice a month is enough to keep their hair looking its best.

If you are using it as a root touch-up, then you may need to use it more often.

Professional toners usually need to be used every 4-6 weeks.

Color-correcting shampoos can be used every 1-2 weeks.

Be sure to test the product on a small area of your scalp before applying it to your entire head.

Can hair toner be used on bleached hair?

Yes, it can be used on bleached hair. Really, it’s a must!

Most toners are designed for use on color-treated hair, which means that they can be used on bleached hair without any problems.

In fact, many blondes find that toner is an essential step in their bleach hair care routine.

Toners help to correct any unwanted yellow or brassy tones, and they can also be used to enhance or change the overall color of your hair.

When shopping for a toner, be sure to look for one that is specifically designed for blondes or for color-treated hair.

Does toner work on natural hair?

If you’re wondering whether you can use hair toner on natural hair, the answer is a resounding YES!

In fact, hair toner can be a great way to enhance your natural hair color.

Just be sure to choose a toner that is specifically designed for use on natural hair. Otherwise, you run the risk of damaging your hair.

What color hair toner do I need?

The color of hair toner that you need will depend on the color of your hair.

If your hair is a warm color (red, orange, yellow), then you will need a toner that is designed to cool down the tone.

If your hair is gray, then you will need a toner that is designed to cover up gray hair.

If your hair is light brown or dark blonde, then you will need a toner that is designed to brighten your hair color.

If you have black hair, then you will need a toner that is designed to add cool tones to your hair.

It’s all to do with color theory and the hair color wheel. Choose a color opposite to the color you want to achieve on the wheel to neutralize unwanted tones.

What volume developer should I use with toner?

When it comes to developers, you’ll notice that there are different strengths available—generally ranging from 10 to 40.

The higher the number, the stronger the developer and the more pigment it will add to your hair color. Most at-home lightening kits come with a 10 or 20-volume developer.

These are ideal strength levels for achieving subtle highlights or refreshing existing highlights (without lightening them).

However, if you’re looking for more dramatic results like lifting your natural hair color by several shades or adding bold fashion colors like red or purple, then you’ll need a higher strength like 30 or 40-volume developer.

When using toner and volume developer together, always make sure that they are mixed in equal parts (unless otherwise specified).

For example, if you’re using a bottle of toner that contains 4 ounces of product and 4 ounces of 20-volume developer, then mix 2 ounces of each into a bowl before applying it onto your hair.

NEVER use more than a Volume 20 developer with a toner. If you use a 30 volume toner or higher, the toner can’t do its job properly and you’ll and up with patchy and uneven color! Ew!

Can I leave toner on for 5 minutes?

You can leave color correcting shampoos on for five minutes before rinsing and conditioning.

Most will need longer than this to work their color freshening magic.

Can you leave toner on longer?

Really, you can only leave them on for as long as the instructions recommend.

More resistants hair types like coarse, thick or particularly porous hair might need to leave it on longer for the toner to take effect.

However, be aware that leaving toner on too long can cause your color to be too dark and your hair to become dry and brittle.

NEVER leave it on overnight or for longer than the instructions tell you to! This will result in over toned hair.

Toner can be hard to remove from your hair if you get it wrong!

What happens if you leave toner in your hair too long?

If you’ve ever left toner in your hair for too long, you know it isn’t a pretty sight.

Your once vibrant locks can become dull, flat, and lifeless.

In extreme cases, toner can even strip away the natural pigment in your hair, leaving you with an unwanted shade of green or blue.

So what happens if you leave toner in your hair for too long? Here’s what you need to know.

Toner is typically used after bleaching or coloring hair to help correct the color. However, if it’s left on for too long, it can have the opposite effect.

The chemicals in toner can react with the natural pigment in your hair, causing it to change color.

In addition, toner can strip away the natural oils in your hair, leaving it dry and brittle.

If you’re hoping to achieve a certain shade of blonde or brunette, it’s best to consult with a professional stylist who can help you find the right toner for your hair type!

What happens if you leave toner in for more than 30 minutes?

If you leave it on for more than 30 minutes, you may end up with a color that is too dark or too light.

Leaving it on too long will also deposit too much color in your hair – which could end up looking green!

We recommend not leaving it in for more than 45 minutes and keeping a watchful eye on it throughout the process.

Do you apply toner to wet or dry hair?

Does toner go on wet hair? Most people apply toners to dry hair or damp hair.

If you’re using a semi-permanent toner like a gloss or glaze, then you should apply the toner onto wet hair. This will give locks that totally envy-worthy shine.

Whereas if you opt for a permanent toner such as a high-lift hair color, then go ahead and apply the product onto dry hair instead.

If you are using a color-correcting shampoo, you will definitely need to wet your hair first!

Glosses can also be applied at the end of coloring your hair to add shine make your hair soft while keeping your color cool.

Why is my hair still brassy after toning?

There are a few reasons why your hair might still be brassy after toning it.

First, if your hair is naturally dark, it can be tricky to get rid of all the brassiness.

Second, if you have highlights or balayage, the toner might not be able to penetrate all the way down to the roots.

Third, if you have previously dyed your hair a dark color, it can be difficult to remove all the pigment.

Finally, if you have sensitive skin, you might need to use a gentler toner.

If you’re still struggling with brassiness, talk to your stylist about other options, such as highlights or lowlights.

Should I shampoo after toner?

Yes my friends! You should shampoo your hair after using any of these products.

They work by depositing color onto your hair.

If you do not shampoo your hair, the color will start to fade and the toner will lose its effectiveness.

Be sure to use a good quality shampoo and conditioner to keep your hair looking its best.

How long do toners last?

Toners are a great way to achieve the color of your dreams without having to completely commit to permanent dye.

But, like all good things, their lives are limited.

Toners do not last as long as the commitment that comes with permanent dye does; most typically toners will fade after seven weeks or so.

To make sure you maintain the vibrant hue you heart and hair desires, touch it up with toner every few months.

Luckily, there are a load of low-commitment hair colors and hair dyes available on today’s market so you can switch up your hue without harming your locks.

Parting words.

So there you have it! Everything you need to know about toners, from how long to leave them in to what happens if you leave them on too long.

Remember to always read the instructions carefully and test the product by doing a strand test before applying it to your entire head.

And most importantly, have fun with it!

Experimenting with different toning products can be a great way to freshen up your look.
