When it comes to hair coloring, one of the most critical decisions you’ll make is choosing the right developer. The developer, also known as the oxidizing agent, plays a crucial role in determining the final result of your hair color. Two of the most common developers used in hair coloring are 20-volume and 30-volume developers. In this article, we’ll delve into the world of hair coloring, exploring the differences between 20-volume and 30-volume developers, and providing you with a comprehensive guide on when to use each.
Understanding Developers and Their Role in Hair Coloring
To understand the difference between 20-volume and 30-volume developers, it’s essential to know what developers do. Developers are used to activate the hair color, allowing it to penetrate the hair shaft and deposit the color. The developer contains hydrogen peroxide, which breaks down the pigment in the hair color and allows it to bond with the hair. The volume of the developer refers to the amount of hydrogen peroxide it contains, which is measured in percentages. A 20-volume developer contains 6% hydrogen peroxide, while a 30-volume developer contains 9% hydrogen peroxide.
The Difference Between 20-Volume and 30-Volume Developers
The primary difference between 20-volume and 30-volume developers is the amount of lift they provide. Lift refers to the ability of the developer to lighten the hair. A 20-volume developer provides minimal lift, usually around 1-2 levels, while a 30-volume developer provides more significant lift, typically around 3-4 levels. This means that if you’re looking to make a dramatic change to your hair color, a 30-volume developer may be the better choice. However, if you’re looking for a more subtle change, a 20-volume developer may be more suitable.
Factors to Consider When Choosing a Developer
When deciding between a 20-volume and 30-volume developer, there are several factors to consider. Your natural hair color, the condition of your hair, and the desired outcome are all crucial factors in determining the right developer for you. If you have damaged or over-processed hair, a 20-volume developer may be a better choice, as it is less harsh on the hair. On the other hand, if you have healthy hair and are looking for a more dramatic change, a 30-volume developer may be the better option.
When to Use a 20-Volume Developer
A 20-volume developer is suitable for a variety of hair coloring applications. It’s an excellent choice for toning, glazing, or making subtle changes to your hair color. If you’re looking to add a hint of color or dimension to your hair without making a dramatic change, a 20-volume developer is a great option.

What is the difference between 20-volume and 30-volume developers?
The difference between 20-volume and 30-volume developers lies in their oxidizing power, which affects the degree of lift they can achieve on the hair. A 20-volume developer is less alkaline and has a lower concentration of hydrogen peroxide, making it suitable for depositing color, glossing, and achieving minimal lift. It is often used for maintaining or enhancing existing color without drastic changes. On the other hand, a 30-volume developer is more alkaline and has a higher concentration of hydrogen peroxide, which allows for more significant lift and is commonly used for lightening hair, achieving noticeable color changes, and for those looking for a more dramatic effect.
When choosing between these two, consider the current condition of the hair, the desired outcome, and the natural color of the hair. For instance, if the goal is to go significantly lighter or to make a major color change, a 30-volume developer might be necessary. However, for individuals looking to maintain their current color, make subtle adjustments, or apply a gloss, a 20-volume developer would be more appropriate. Understanding the specific needs of the hair and the desired end result is crucial in selecting the right developer volume for optimal results without causing undue stress or damage to the hair.
How do I determine the right developer for my hair type?
Determining the right developer for your hair type involves considering factors such as the porosity, elasticity, and previous chemical treatments of your hair. For example, if you have damaged or over-processed hair, a lower volume developer (like 20-volume) might be gentler and less likely to cause further damage. Conversely, if you have very resistant hair, you might need a higher volume developer to achieve the desired lightening or color deposit effect. It’s also crucial to assess your hair’s porosity—that is, how well your hair can absorb and hold moisture—and its elasticity, or how well it can stretch without breaking.
When in doubt, consulting a professional hairstylist is advisable, as they can provide personalized recommendations based on a thorough assessment of your hair. A hairstylist can perform a strand test to determine how your hair reacts to different developer volumes, ensuring the best possible outcome for your specific hair needs. This step is particularly important for those looking to achieve a significant color change or lightening, as the health and integrity of the hair can significantly affect the final result and the hair’s ability to withstand the chemical process.
What are the risks associated with using the wrong developer volume?
Using the wrong developer volume can lead to a range of undesirable outcomes, including over-processing, under-processing, and damage to the hair. Over-processing, often a result of using too high a volume developer, can cause the hair to become dry, brittle, and prone to breakage. This is because higher volume developers contain more hydrogen peroxide, which, when used in excess, can strip the hair of its natural oils and lead to structural damage. On the other hand, under-processing, which might occur with too low a volume developer, can result in the desired color change not being achieved, necessitating repeated treatments that further stress the hair.
The risks associated with inappropriate developer use underscore the importance of careful planning and consultation with a professional, especially for those new to hair coloring or lightening. A strand test is a crucial precautionary measure that can help identify potential issues before applying the developer to the entire head of hair. It allows for adjustments in developer volume or application time to ensure the best possible results while minimizing the risk of damage. Being informed and taking necessary precautions can significantly mitigate these risks, ensuring a successful and safe coloring or lightening experience.
Can I mix different developer volumes to achieve a custom effect?
While it’s technically possible to mix different developer volumes to achieve a custom effect, this practice is generally not recommended for amateur use. Professional hairstylists, with their extensive training and experience, might occasionally mix developer volumes as part of a customized treatment to achieve a very specific result. However, for most applications, especially for those who are not professionals, it’s advisable to stick with the standard developer volumes (such as 20-volume or 30-volume) that are widely recognized and tested for safety and efficacy.
Mixing developer volumes without proper understanding and expertise can lead to unpredictable results, including uneven processing, over-processing, and damage to the hair. The exact mix of different developer volumes can be complex to calculate and apply correctly, requiring a deep understanding of hair chemistry and the interactions between different developer concentrations. Moreover, such practices might void warranties or guarantees provided by the manufacturer of the hair coloring or lightening products. Therefore, unless under the guidance of a professional stylist, it’s best to adhere to the recommended developer volumes to ensure safe and effective hair treatment.
How does the condition of my hair affect the choice of developer volume?
The condition of your hair plays a significant role in choosing the right developer volume. Hair that is damaged, over-processed, or fragile requires a more gentle approach, typically suggesting the use of a lower volume developer to minimize further stress and potential breakage. On the other hand, hair that is resistant or very dense might require a higher volume developer to achieve the desired effect, as it can withstand more aggressive chemical processing. The porosity and elasticity of the hair are also critical factors, as they influence how well the developer penetrates the hair shaft and achieves the desired color change or lightening.
For hair that has undergone previous chemical treatments, such as perms, relaxers, or previous color applications, caution must be exercised. Such hair may be more susceptible to damage from further chemical processing, necessitating a lower volume developer or special conditioning treatments before and after the application to protect the hair. Understanding the current state of your hair and its history of chemical treatments is vital in making an informed decision about the developer volume. This knowledge, combined with professional guidance when needed, can help ensure that the chosen developer volume is appropriate for achieving the desired results while preserving the health and integrity of the hair.
Are there any specific developer volumes recommended for virgin hair versus previously colored hair?
For virgin hair (hair that has never been chemically treated), the choice of developer volume depends on the desired outcome. If the goal is to achieve a subtle, natural-looking color change, a lower volume developer (like 20-volume) might be preferable to avoid over-processing and to maintain the hair’s natural shine and health. However, for more significant lightening or color changes, a higher volume developer could be necessary, although with caution to avoid damage. For previously colored hair, the approach can be more complex, as the existing color and the condition of the hair after previous treatments must be considered. Generally, a lower volume developer is recommended for previously colored hair to avoid further stress and potential damage.
The key to working with either virgin or previously colored hair is to approach with caution and consider the long-term health of the hair. If the hair has been heavily processed in the past, it may be more resistant to color or lightening treatments, requiring adjustments in developer volume or additional treatments to achieve the desired effect safely. Consulting with a professional hairstylist can provide personalized advice tailored to the specific history and condition of the hair, helping to navigate the complexities of hair coloring and lightening to achieve beautiful, healthy-looking results. This professional guidance is invaluable in ensuring that the developer volume chosen is both effective and safe for the hair.
