Achieving the perfect hair color can feel like an art and a science. One crucial element in that process, particularly when aiming for cool blondes, is understanding how long to leave toner in with 20 developer. This guide dives deep into the nuances of toner application, the role of 20 volume developer, and the factors influencing processing time to help you achieve salon-worthy results at home.
Understanding Toner and Its Purpose
Toner isn’t just another step in the coloring process; it’s a vital tool for refining and enhancing your hair color. It primarily works by neutralizing unwanted undertones that emerge after bleaching or lightening. These undertones can manifest as brassiness (orange or yellow hues) or redness, which many people find undesirable, especially when aiming for cooler shades of blonde, silver, or gray.
Toner works its magic by depositing pigments that counteract these unwanted undertones. For example, a purple-based toner will neutralize yellow tones, while a blue-based toner combats orange tones. The end result is a more balanced, polished, and professional-looking hair color.
Toner also helps to blend highlights seamlessly, creating a more natural and cohesive look. It can add shine and dimension to the hair, making it appear healthier and more vibrant. Think of it as the finishing touch that transforms your hair from “good” to “gorgeous.”
The Role of 20 Volume Developer
The developer, also known as peroxide, is a key component in the toning process. It’s responsible for opening the hair cuticle, allowing the toner’s pigments to penetrate the hair shaft. Different developer volumes exist, each with varying levels of lifting power. 20 volume developer is a popular choice for toning because it offers a balance between lifting and depositing pigment.
Using 20 volume developer with toner gently opens the hair cuticle, allowing the toner to effectively deposit its color-correcting pigments. It provides enough lift to ensure the toner adheres to the hair but isn’t so strong that it causes significant damage or further lightening. This is especially important for previously lightened hair, which is already vulnerable.
Choosing the right developer volume is critical for achieving the desired results and maintaining the health of your hair. A lower volume developer (like 10 volume) might not provide enough lift for the toner to effectively neutralize undertones, while a higher volume developer (like 30 or 40 volume) could lead to excessive lightening and damage, particularly on already processed hair.
Determining the Ideal Processing Time
The question of how long to leave toner in with 20 developer doesn’t have a one-size-fits-all answer. Several factors influence the optimal processing time, requiring careful consideration and monitoring.
Hair Porosity
Hair porosity refers to the hair’s ability to absorb and retain moisture. Highly porous hair has a more open cuticle, allowing it to absorb products quickly but also lose them just as fast. Low porosity hair, on the other hand, has a tightly closed cuticle, making it more resistant to absorption.
-
High Porosity: Porous hair tends to grab onto toner quickly, potentially leading to over-toning or uneven results. Start with a shorter processing time, around 5-10 minutes, and closely monitor the hair’s color change.
-
Low Porosity: Low porosity hair may require a longer processing time for the toner to effectively penetrate the cuticle. Begin with the recommended time (around 15-20 minutes) and check the color development regularly.
Desired Tone
The specific shade you’re trying to achieve will also influence the processing time. For example, achieving a subtle, cool blonde may require a shorter processing time than aiming for a vibrant silver or platinum shade.
-
Subtle Toning: If you’re simply looking to neutralize a slight amount of brassiness, a shorter processing time (around 10-15 minutes) might suffice.
-
Intense Toning: For more dramatic color correction or to achieve a significantly cooler tone, a longer processing time (up to 25-30 minutes) may be necessary. However, always monitor the hair closely to prevent over-toning.
Starting Hair Color
The starting color of your hair plays a crucial role in determining the processing time. If your hair is already very light (level 9 or 10), the toner will likely process faster than if your hair is a darker blonde (level 7 or 8).
-
Light Blonde (Level 9-10): Light blonde hair is highly susceptible to toner, so start with a shorter processing time and monitor closely.
-
Darker Blonde (Level 7-8): Darker blonde hair may require a slightly longer processing time to achieve the desired tone.
Toner Formulation
Different toner formulations can have varying processing times. Some toners are designed to process quickly, while others are formulated for a slower, more gradual color change. Always refer to the manufacturer’s instructions for the specific toner you are using. Ignoring the manufacturer’s guidelines can lead to unpredictable results.
The Recommended Time Frame: A Starting Point
While the factors above influence processing time, a general recommendation for leaving toner in with 20 developer is typically between 15 and 30 minutes. However, this is merely a starting point. Frequent monitoring is essential to prevent over-toning.
Start by applying the toner evenly throughout your hair, ensuring complete saturation. Set a timer for 10 minutes and begin checking the color development. Continue checking every few minutes until you reach your desired tone.
How to Monitor Color Development
Regularly checking the color development is crucial to avoid over-toning. This involves wiping away a small section of the toner to assess the underlying color.
-
Wipe Away: Use a damp paper towel to gently wipe away the toner from a small, inconspicuous section of your hair.
-
Assess the Color: Examine the exposed hair color under good lighting. If the undertones are neutralized and you’ve achieved your desired tone, it’s time to rinse.
-
Repeat: If the color is not yet where you want it to be, reapply the toner to the section you wiped away and continue processing for a few more minutes, checking again until you reach the desired result.
What Happens If You Leave Toner in Too Long?
Leaving toner in too long can lead to over-toning, resulting in hair that appears muddy, ashy, or even darker than intended. Over-toned hair can also feel dry and brittle due to the prolonged exposure to the developer.
If you accidentally over-tone your hair, don’t panic. There are several steps you can take to correct the color:
-
Wash with Clarifying Shampoo: A clarifying shampoo can help to remove excess toner pigments from the hair. Wash your hair thoroughly and repeat if necessary.
-
Apply a Deep Conditioner: Over-toning can leave the hair feeling dry, so follow up with a deep conditioning treatment to restore moisture and improve its overall health.
-
Use a Color Remover: For more severe cases of over-toning, a color remover can be used to gently lift the unwanted pigments. Follow the manufacturer’s instructions carefully and always perform a strand test first.
Tips for Successful Toning
-
Perform a Strand Test: Before applying toner to your entire head, always perform a strand test. This will allow you to assess how the toner interacts with your hair and determine the optimal processing time.
-
Use Quality Products: Invest in high-quality toner and developer. Cheaper products may contain harsh chemicals that can damage your hair.
-
Apply Evenly: Ensure even application of the toner to prevent patchy or uneven results. Use a tint brush to thoroughly saturate each strand of hair.
-
Monitor Closely: As mentioned earlier, frequent monitoring is key to preventing over-toning.
-
Follow the Instructions: Always adhere to the manufacturer’s instructions for the specific toner and developer you are using.
-
Condition Regularly: Toning can be drying, so incorporate regular deep conditioning treatments into your hair care routine.
-
Consider Professional Help: If you’re unsure about any aspect of the toning process, consult a professional hairstylist. They can assess your hair and provide personalized recommendations.

What is the typical processing time for toner with 20 volume developer?
The typical processing time for toner mixed with a 20 volume developer generally ranges from 10 to 20 minutes. However, this timeframe is highly dependent on the brand of toner, the desired result, and the porosity of your hair. Always refer to the specific instructions provided by the toner manufacturer for their recommended processing time, as exceeding it can lead to unwanted color changes or damage to your hair.
It’s crucial to closely monitor your hair’s progress during the toning process. Start checking your hair color after 10 minutes and continue checking every few minutes thereafter. The goal is to achieve the desired tone without over-processing, which can result in a muddied or overly ashy color. Keeping a watchful eye and adhering to the manufacturer’s guidelines are key to a successful toning experience.
Why is 20 volume developer often used with toner?
A 20 volume developer is a common choice when using toner because it provides a balance between lifting and depositing color. Toners primarily deposit color to neutralize unwanted tones (like yellow or orange) rather than drastically lightening the hair. The 20 volume developer offers a subtle lift, allowing the toner to penetrate the hair shaft and effectively neutralize these unwanted tones.
This level of developer is also gentle enough to avoid excessive damage to pre-lightened hair, which is often porous and more susceptible to breakage. Higher volume developers, while capable of greater lift, are usually unnecessary and potentially damaging when using toner to achieve the desired color correction and tonal balance. The gentler action of the 20 volume ensures a more even and controlled toning process.
What happens if I leave toner in for too long with 20 volume developer?
Leaving toner in for longer than the recommended time when using a 20 volume developer can lead to several undesirable outcomes. One common issue is over-toning, which can result in your hair becoming overly ashy, muddy, or even taking on a purple or blue tint. This is because the toner continues to deposit pigment onto the hair shaft, exceeding the intended color correction.
Furthermore, prolonged exposure to the chemicals in the toner and developer, even a relatively gentle one like 20 volume, can cause damage to the hair. This can manifest as dryness, brittleness, and increased susceptibility to breakage. Always adhere to the manufacturer’s recommended processing time and closely monitor your hair’s color during the toning process to avoid these issues.
How do I determine the correct processing time for my hair?
Determining the correct processing time depends on several factors. Start by consulting the instructions that come with your chosen toner. These instructions often provide a recommended range, such as 10-20 minutes, but remember that this is a general guideline. Your hair’s porosity, its current color, and the desired outcome all play a role.
If your hair is highly porous (meaning it absorbs liquids quickly), it will likely process the toner faster. Similarly, if your hair is already close to the desired tone, you may need a shorter processing time. Perform strand tests before applying toner to your entire head. This involves applying the toner mixture to a small, inconspicuous section of your hair and checking the color every few minutes to determine the optimal processing time for your specific hair type and desired result.
Can I use a lower volume developer, like 10 volume, with toner?
Yes, you can definitely use a 10 volume developer with toner, especially if your hair is already very light and you only need to deposit color without lifting. A 10 volume developer is even gentler than a 20 volume, minimizing the risk of damage and is ideal for fine or fragile hair. This can also be preferable if your primary goal is to neutralize brassiness without significantly altering the base shade.
Using a 10 volume developer will result in a slower processing time compared to a 20 volume, so you might need to leave the toner on for slightly longer to achieve the desired results. However, it provides a more controlled and gentle approach, making it less likely to over-tone your hair. Always monitor your hair’s progress and conduct a strand test beforehand to ensure you achieve the desired tone without causing damage.
What if I accidentally leave the toner in for too long?
If you accidentally leave the toner in for too long and your hair becomes overly toned, don’t panic. There are several ways to address the situation. One option is to wash your hair immediately with a clarifying shampoo. This can help to remove some of the excess toner and lighten the color.
You can also try using a color-removing shampoo or a bleach wash (a very diluted bleach mixture applied for a short period), but proceed with caution as these methods can be damaging. Regularly deep conditioning your hair after attempting to remove excess toner is essential to replenish moisture and prevent breakage. In severe cases, consulting a professional hairstylist is recommended to correct the color without further damage.
How often can I tone my hair with 20 volume developer?
The frequency with which you can tone your hair using a 20 volume developer depends largely on the health and porosity of your hair. Generally, it’s best to avoid toning more frequently than every 4-6 weeks to prevent over-processing and potential damage. Frequent toning, even with a relatively low-volume developer, can lead to dryness, brittleness, and breakage over time.
Between toning sessions, focus on maintaining your hair’s health by using moisturizing shampoos and conditioners, deep conditioning treatments, and heat protectants when styling. If you notice any signs of damage, such as increased dryness or breakage, consider extending the time between toning sessions or consulting with a professional hairstylist for personalized advice. Prioritizing hair health will help ensure that your toning efforts result in beautiful, vibrant color without compromising the integrity of your hair.
