Understanding Hair Developers
Before we dive into the process of making a 40 volume developer, it’s essential to understand what hair developers are and how they work. Hair developers, also known as oxidizing agents, are used in conjunction with hair color or bleach to activate the coloring process. They contain hydrogen peroxide, which opens up the hair cuticle, allowing the color to penetrate and develop. The volume of a developer refers to its strength, measured by the percentage of hydrogen peroxide it contains. The most common developer volumes are 10, 20, 30, and 40.
Volumes and Their Uses
- 10 Volume Developer: Used for depositing color or making minor adjustments to existing color. It has a low lifting power and is often used for touch-ups or coloring previously colored hair.
- 20 Volume Developer: Offers a moderate lifting power and is commonly used for covering gray hair or making significant color changes.
- 30 Volume Developer: Provides a stronger lifting power than 20 volume and is used for lightening hair up to three shades.
- 40 Volume Developer: The strongest developer commonly used, offering a high lifting power. It is used for significant lightening, up to four shades, but requires caution due to its potency.
Making a 40 Volume Developer
Making a 40 volume developer involves mixing hydrogen peroxide with a stabilizer and possibly other ingredients to ensure stability and safety. The process requires precision and caution, as handling high concentrations of hydrogen peroxide can be hazardous.

Mixing the Developer
To make a 40 volume developer, you will need pure hydrogen peroxide and a stabilizer. The stabilizer helps in preventing the decomposition of hydrogen peroxide over time, ensuring the developer remains effective.
The formula for making a 40 volume developer involves calculating the right concentration of hydrogen peroxide. Since commercial developers are readily available and formulated for safety and efficacy, making your own is not typically recommended unless you are experienced and understand the risks and chemical interactions involved.
However, for educational purposes, a 40 volume developer contains 12% hydrogen peroxide. This concentration is strong and should be handled with care.
Calculations for Making a 40 Volume Developer
If you are looking to mix your own developer from a more concentrated hydrogen peroxide solution, you would need to calculate the right dilution. For example, if you have a 35% hydrogen peroxide solution (commonly found in beauty supply stores for making nail whiteners or as a strong disinfectant), you would dilute it with distilled water to achieve a 12% solution.
The calculation involves determining how much of the concentrated solution and water are needed to achieve the desired volume and concentration of the 40 volume developer. This requires understanding of chemistry and careful measurement to avoid mistakes.
Applications and Considerations
A 40 volume developer is used for significant lightening of the hair and is often employed in bleaching or high-lift coloring processes. However, due to its strong nature, it can be damaging to the hair if not used correctly. It’s crucial to follow the manufacturer’s instructions for application time, and to perform a strand test before applying the developer to the entire head.
Importance of Strand Testing
A strand test is a preliminary procedure where a small section of hair is treated with the color and developer mixture to check the results and ensure the desired outcome. This step is crucial for avoiding over-processing and potential damage to the hair.
Conclusion
Making a 40 volume developer requires attention to detail, understanding of chemical interactions, and adherence to safety protocols. While it’s possible to calculate and mix your own developer from concentrated hydrogen peroxide solutions, the risks involved make it generally advisable to use commercially available products that are formulated for safety and efficacy.
