Use 20 volume developer for a 1-2 level lift, ideal for covering grey hair. Choose 30 volume for a 2-3 level lift. Use 40 volume for a lift of 3 or more levels, especially on difficult hair. Always follow safety guidelines and conduct a strand test before bleaching.
A 30 volume developer provides a stronger lift, typically lifting hair by three to four shades. This developer is suitable for those seeking a more noticeable change in their hair color. However, it can also increase the risk of damage if not used properly.
A 40 volume developer offers the highest lift, allowing for more than four shades of lightening. It is often used for dramatic transformations, but it can lead to significant hair damage if not carefully monitored. This level of developer is best handled by professionals.
Choosing the right volume depends on your hair type, desired results, and your experience level with bleaching. If you’re new to hair bleaching, starting with a lower volume may be wise. Understanding the appropriate developer will lead to healthier hair and better results. Next, we will explore the best practices for using these developers effectively.
What Is Hair Bleach and How Does It Work?
Hair bleach is a chemical product used to lighten hair by removing its pigmentation. It contains an oxidizing agent, typically hydrogen peroxide, which interacts with the hair’s melanin.
The American Academy of Dermatology describes hair bleach as a “chemical process that uses substances to remove color from hair.” This process alters the hair’s natural pigment, resulting in a lighter shade.
Hair bleach works by penetrating the hair shaft and breaking down the melanin, the natural pigment responsible for hair color. Different strengths, or volumes, of developer are used based on the desired degree of lightening. Higher volumes increase the intensity of the bleaching effect.
According to the American Society of Dermatology, bleaching can cause hair damage, resulting in dryness and brittleness. It is recommended that users perform a patch test prior to full application to check for allergic reactions.
Multiple factors contribute to the effectiveness and safety of hair bleach, including the hair’s natural color, texture, and health. Darker hair may require more time or a higher volume of developer for desired results.
Statistics show that 34% of women in the U.S. bleach their hair, according to a report by Statista in 2020. This growing trend reflects the desire for lighter hair shades and changing beauty standards.
The broader impacts of hair bleach include potential environmental concerns due to chemical runoff and hair waste during the bleaching process. These chemicals can harm aquatic ecosystems if not properly managed.
Health implications include scalp irritation and allergic reactions to bleaching agents. Emotional impacts can arise from dissatisfaction with hair color or damage caused by bleach.
To mitigate the risks of using hair bleach, experts recommend using lower volumes, following application guidelines carefully, and performing patch tests.
Practices such as regular moisturizing treatments and minimizing bleach use can help maintain hair health. Consulting professional stylists for safe applications is also advised.

2. Desired lift
3. Processing time
4. Hair color and previous treatments
5. Developer strength
Understanding these factors helps ensure optimal results and minimizes hair damage.
-
Hair Type and Condition:
When choosing developer volume, it’s crucial to assess your hair type and condition. Hair that is fine or damaged may require gentler treatment. Conversely, coarse or healthy hair may tolerate stronger developers. The general rule of thumb is to use lower volumes (10 or 20) on weaker hair and higher volumes (30 or 40) on stronger hair. -
Desired Lift:
The desired lift also influences the choice of developer volume. A 10-volume developer provides minimal lift and is best suited for depositing color. A 20-volume developer lifts hair one to two levels, making it ideal for darkening or subtle highlights. A 30-volume developer allows for three levels of lift and is often used for lighter shades. A 40-volume developer, while providing the maximum lift, is typically reserved for achieving drastic changes and should be used cautiously. -
Processing Time:
Processing time is another key factor in selecting developer volume. A stronger developer may shorten processing time due to its potency, but this can increase the risk of damage. It’s essential to follow the manufacturer’s guidelines and perform strand tests to determine the appropriate processing time for your hair type and developer volume. -
Hair Color and Previous Treatments:
The existing hair color and any past treatments can affect how the hair interacts with the developer. Previously bleached or colored hair may respond differently compared to virgin hair. Understanding your hair’s history is vital to avoid unwanted results, such as excessive damage or undesirable tones. -
Developer Strength:
Developer strength plays a significant role in determining how much lift is achieved. Volume levels range from 10 to 40, with each level corresponding to the amount of hydrogen peroxide present. Higher volumes contain more hydrogen peroxide, leading to more significant chemical reactions. Therefore, choosing an appropriate strength is critical for achieving the desired outcome while preserving hair health.
Selecting the right developer volume depends on individual needs and hair characteristics. By carefully considering these factors, one can achieve vibrant colors while minimizing potential damage.
How Does Hair Type Influence Developer Volume Selection?
Hair type significantly influences the choice of developer volume when lightening or coloring hair. Hair texture, porosity, and thickness are the main components to consider. Each type of hair reacts differently to chemical processes.
First, identify the hair texture. Fine hair typically requires a lower volume developer, such as 20 volume. This choice minimizes damage while still achieving color lift. In contrast, coarse hair can endure a higher volume, like 30 or even 40 volume developer, since it absorbs color more readily and requires more power to lift effectively.
Next, evaluate hair porosity. High-porosity hair, which absorbs moisture easily, may respond well to a lower developer volume. This approach prevents over-processing and damage. Conversely, low-porosity hair often needs a higher volume developer to penetrate the tightly sealed cuticles for effective lift.
Then, consider the hair’s thickness. Thick hair usually handles higher developer volumes better. Using a 30 or 40 volume on thick hair can provide the necessary lift for even coloring.
In summary, base your developer volume selection on hair texture, porosity, and thickness. Fine hair usually benefits from 20 volume, while coarse hair can often handle 30 or 40 volume. Always test a small section first to determine how the individual hair type responds. This method minimizes damage and maximizes desired results.
