When to use hair toner.

  • If your hair has unwanted warmth to it

  • If you have bleached or very light blonde hair.

Step-by-Step Guide to Using Hair Toner

1. Choose Your Toner Type

Before anything else, select the right type of toner for your hair needs.

This could be a professional toner for more dramatic changes, a color-correcting shampoo for slight adjustments, or a gloss to add shine and subtle toning.

Consider your hair condition, desired outcome, and whether your hair is natural, colored, or bleached.

2. Prepare Your Hair

Wash your hair with a clarifying shampoo to remove any buildup and ensure the toner can work effectively.

Do not use conditioner at this stage as it may block the toner from penetrating the hair strands.

Towel-dry your hair gently to remove excess water; toner is typically applied to damp hair unless the specific product instructions suggest otherwise.

3. Mix the Toner and Developer (If Required)

If you’re using a toner that requires mixing with a developer, follow the product instructions closely.

Typically, the mixture is in equal parts, but this can vary. Use a non-metallic bowl and utensil to mix the toner and developer to avoid any chemical reaction that might affect the toning process.

4. Apply the Toner

Wear gloves to protect your hands. Start applying the toner from the roots to the ends, using a tint brush for even distribution.

If you’re focusing on specific areas like highlights or combating brassiness, apply the toner only where needed. Use clips to section off your hair and ensure no strand is missed.

5. Monitor the Development Time

The development time can vary from 5 to 45 minutes, depending on the product type and desired outcome. Check the color every 5-10 minutes by wiping away a small amount of toner with a damp towel. This will help you avoid over-toning or achieving a color too dark for your liking.

6. Rinse Thoroughly

Once you’ve reached your desired shade, rinse your hair thoroughly with lukewarm water. Make sure all the toner is washed out to avoid any further color change.

7. Shampoo and Condition

After rinsing, shampoo your hair to ensure all residues are removed.

Follow up with a hydrating conditioner or a hair mask to replenish moisture and seal the hair cuticles. This step will also help to lock in the color and add shine.

8. Dry and Style as Usual

Gently towel-dry your hair and proceed to dry and style as you normally would. Enjoy your refreshed and toned hair color!

9. Maintenance

To maintain your toned hair color, consider using color-protecting shampoos and conditioners.

Depending on the toner’s longevity and your hair growth, you might need to reapply the toner every 4-6 weeks or as needed.

Choosing the Right Volume for Hair Toner

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!

Expert Insights

“When it comes to selecting the right volume for your hair toner, the most important factor to consider isn’t just the level of lift you’re aiming for; it’s also about understanding the unique characteristics of your hair. Each head of hair reacts differently to toner and developer, depending on its history and health.”

Enza Piazza, Hair Stylist & Color Consultant

Selecting the Correct Hair Toner Color

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.

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.

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.

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.
