Deciding on the right developer volume for your hair dye can feel like navigating a complex chemical equation. Understanding the difference between a 20 and 30 volume developer is crucial for achieving your desired hair color results while minimizing damage. This article will delve into the nuances of each developer, helping you make an informed choice for your next hair transformation.
Understanding Developer and Its Role
Developer, also known as hydrogen peroxide, is a key component in hair dyeing. It acts as an oxidizing agent, meaning it opens the hair cuticle, allowing the dye molecules to penetrate the hair shaft. Simultaneously, it lightens the natural hair pigment, making way for the new color. The volume of the developer indicates its strength – a higher volume means a stronger oxidizing action.
How Developer Works
The process involves a chemical reaction. The developer lifts the natural melanin in your hair, the pigment that determines its color. This lifting action is what allows the artificial dye molecules to deposit and create the desired shade. The higher the volume, the more significant the lift.
Developer and Hair Damage
It’s important to remember that any chemical process, including hair dyeing, can cause some degree of damage. The higher the developer volume, the greater the potential for damage. Over-processing can lead to dryness, breakage, and overall weakened hair. Choosing the correct developer volume is therefore essential to maintain hair health.
20 Volume Developer: The Gentle Option
A 20 volume developer contains approximately 6% hydrogen peroxide. It provides a milder lifting action and is generally considered a safer option for many hair coloring situations.
When to Use 20 Volume Developer
This developer is ideal for:
- Depositing color: If you are simply aiming to deposit color without significant lightening, such as going darker or covering gray hair, 20 volume is often sufficient.
- Covering gray hair: It effectively opens the cuticle to allow color to penetrate and cover resistant gray strands.
- Toning: When using toners to neutralize unwanted tones (like brassiness), 20 volume can provide the necessary lift without causing excessive damage.
- Subtle lightening: For lifting one level, a 20 volume developer might be appropriate, especially on finer or more damaged hair.
- Color matching: if you have a similar hair tone to your desired color.
Pros of Using 20 Volume Developer
The advantages of using a lower volume developer include:
- Less damage: It’s gentler on the hair, minimizing dryness and breakage.
- More predictable results: The lifting action is more controlled, leading to more predictable color outcomes.
- Suitable for sensitive scalps: Lower peroxide concentration can be less irritating for those with sensitive scalps.
Cons of Using 20 Volume Developer
The drawbacks of using 20 volume developer involve:
- Limited lifting power: It may not be strong enough to achieve significant lightening, especially on darker hair.
- Longer processing time: It may require a longer processing time to achieve the desired result.
- May not cover resistant grays completely: On very resistant grays, it may not provide complete coverage.
30 Volume Developer: The Stronger Choice
A 30 volume developer contains approximately 9% hydrogen peroxide. It’s a stronger oxidizing agent that provides more significant lifting action.
When to Use 30 Volume Developer
Consider using a 30 volume developer when:
- Lifting 2-3 levels: If you want to lighten your hair by two to three shades, 30 volume is generally recommended.
- Lifting darker hair: To achieve noticeable lightening on dark brown or black hair, a stronger developer is often necessary.
- Using high-lift colors: Some hair dyes are specifically formulated to be used with 30 volume developer for optimal results.
- Stubborn gray coverage: When covering resistant grays, particularly on hair that is naturally dark, a 30 volume developer can help to ensure complete coverage.
Pros of Using 30 Volume Developer
The benefits of opting for a higher volume developer are:
- Faster processing time: It works faster, reducing the overall time your hair is exposed to chemicals.
- More dramatic results: It can achieve more significant lightening and color changes.
- Better gray coverage for stubborn hair: Provides more effective gray coverage for very resistant grays.
Cons of Using 30 Volume Developer
Be aware of the potential downsides:
- Increased damage: The higher peroxide concentration can lead to more dryness, breakage, and overall damage.
- Greater risk of over-processing: It’s easier to over-process the hair, resulting in unwanted tones or damage.
- Potential for scalp irritation: The stronger solution can be more irritating for sensitive scalps.
Key Differences: 20 Volume vs. 30 Volume
The primary difference lies in the concentration of hydrogen peroxide. This difference directly impacts the lifting power and potential for damage.
Lifting Power
20 volume is generally used for depositing color or lifting one level, whereas 30 volume is designed for lifting two to three levels.
Damage Potential
30 volume carries a higher risk of hair damage compared to 20 volume. Careful monitoring and proper hair care are crucial when using a 30 volume developer.
Processing Time
30 volume processes faster than 20 volume. You need to carefully monitor the color development to avoid over-processing.
Factors to Consider When Choosing
Selecting the appropriate developer volume depends on several factors, including your current hair color, desired outcome, hair health, and hair type.
Current Hair Color
Darker hair requires a higher volume developer to achieve noticeable lightening. Lighter hair can often achieve the desired result with a lower volume.
Desired Outcome
If you’re aiming for a subtle color change or simply covering grays, 20 volume is likely sufficient. For more dramatic lightening, 30 volume might be necessary.
Hair Health
Damaged or over-processed hair requires a gentler approach. Using a 20 volume developer minimizes further damage. Healthy hair can typically tolerate a 30 volume developer, but careful monitoring is still essential.
Hair Type
Fine hair tends to process faster and is more susceptible to damage, so a lower volume developer is generally recommended. Coarse hair may require a higher volume developer to achieve the desired lift.
Tips for Safe Hair Dyeing
Regardless of the developer volume you choose, following these tips can help minimize damage and achieve the best possible results.
- Perform a strand test: Before applying dye to your entire head, test it on a small, inconspicuous section of hair to assess the color and processing time.

Choosing between a 20 and 30 volume developer hinges on understanding your hair, your goals, and the potential risks. By carefully considering the factors outlined in this article, you can make an informed decision and achieve beautiful, healthy, and vibrant hair color. Always remember to prioritize the health of your hair and seek professional guidance when needed.
What is the difference between 20 volume and 30 volume developer?
The main difference between 20 and 30 volume developer lies in the amount of hydrogen peroxide they contain. 20 volume developer contains 6% hydrogen peroxide, while 30 volume developer contains 9%. This difference in peroxide concentration determines the level of lift (lightening) the developer can achieve, as well as the speed at which it works. 30 volume lifts faster and lighter than 20 volume.
Essentially, 20 volume is gentler and deposits more color, making it ideal for covering grays, toning, or going slightly darker. 30 volume, on the other hand, provides more significant lift, allowing you to go several shades lighter. It’s crucial to understand your hair’s condition and desired result to choose the right volume, minimizing damage and achieving the intended outcome.
When should I use 20 volume developer?
20 volume developer is best suited for situations where minimal lift is required. This includes depositing color (going darker), covering gray hair, maintaining your current hair color (refreshing the tone), or lifting only one to two levels lighter. It’s a good choice for those with delicate or damaged hair, as it’s less harsh and reduces the risk of further damage. Think of it as a gentle option for subtle color changes.
Specifically, if you’re using a demi-permanent hair color, a 20 volume developer is the standard choice. It opens the hair cuticle just enough to deposit the color effectively without causing significant lightening. Also, it’s preferred when you want to avoid brassiness, especially when working with darker shades. The lower volume allows for a controlled and gradual color change.
When is 30 volume developer the better choice?
30 volume developer is the preferred option when you need to lift your hair color by two to three levels. This is often necessary when aiming for a significantly lighter shade, such as going from dark brown to light brown or from medium brown to blonde. If your hair is naturally resistant to color changes, or if you have previously colored hair that needs to be lifted before applying a new shade, 30 volume can provide the necessary power.
However, it is crucial to remember that 30 volume developer is stronger and can cause more damage than 20 volume. Therefore, it’s not recommended for already damaged or fragile hair. A strand test is highly advised before applying 30 volume developer to your entire head, ensuring your hair can handle the strength of the developer and achieve the desired result without excessive breakage or damage.
Can I mix 20 and 30 volume developer to get a 25 volume?
While mathematically mixing 20 and 30 volume developers might seem like a way to achieve a 25 volume equivalent, this is generally not recommended. The chemical reaction of the developers is not always predictable, and the resulting mixture may not perform as expected. The overall strength and performance can be inconsistent, potentially leading to uneven color results or unexpected damage.
Instead of mixing, it’s better to stick to commercially available developers with a known and tested volume. If a 25 volume developer is not readily available, consider using a 20 volume for a gentler lift or a 30 volume with careful monitoring and shorter processing times to minimize potential damage. Focus on choosing the correct process over trying to alter the solution itself.
Will using 30 volume developer always result in lighter hair than 20 volume?
Yes, generally speaking, 30 volume developer will result in a lighter hair color compared to 20 volume, assuming the same hair dye is used. The higher concentration of hydrogen peroxide in 30 volume allows it to lift the natural pigment of the hair more effectively, resulting in a greater degree of lightening. However, the final outcome depends on various factors, including your natural hair color, hair porosity, and the specific dye used.
It’s essential to consider the potential for damage and unwanted brassiness when using 30 volume. While it can achieve a lighter result, it also increases the risk of over-processing and dryness. If you only need a subtle lift, 20 volume might be a safer option. Always perform a strand test to gauge how your hair reacts to the developer and ensure you achieve the desired lightness without compromising its health.
How do I choose between 20 and 30 volume if I have gray hair to cover?
When covering gray hair, 20 volume developer is generally preferred if you’re staying close to your natural hair color or going darker. It provides sufficient lift to open the hair cuticle and allow the color to penetrate and effectively cover the gray strands. The lower volume is gentler on the hair, which can be beneficial as gray hair tends to be coarser and potentially more resistant to color absorption. It also minimizes damage on already aging hair.
If you’re aiming for a significantly lighter shade while covering gray, 30 volume developer might be necessary to achieve the desired level of lift. However, this comes with an increased risk of damage and potential brassiness, particularly if your hair is naturally dark. It is vital to assess the condition of your hair and perform a strand test. You might also consider using a lower volume developer with a longer processing time to achieve the necessary coverage while minimizing the risk of damage.
What safety precautions should I take when using any hair dye developer?
Regardless of whether you’re using 20 or 30 volume developer, it’s crucial to prioritize safety. Always wear gloves to protect your skin from irritation and chemical burns. Perform a patch test on a small area of skin 48 hours before applying the developer to your entire head to check for any allergic reactions. Avoid getting the developer in your eyes, and if contact occurs, rinse immediately with plenty of water.
Work in a well-ventilated area to minimize exposure to fumes. Follow the manufacturer’s instructions carefully regarding mixing ratios and processing times. Never leave the developer on your hair for longer than recommended, as this can lead to over-processing and significant damage. After processing, rinse your hair thoroughly and use a deep conditioner to replenish moisture and help restore its health.
