Can You Mix 30 and 20 Developer? A Comprehensive Guide to Hair Color Mixing

Mixing hair color developers is a common question among both professional hair stylists and at-home colorists. Understanding developer volumes and their interactions is crucial for achieving desired results and avoiding potential hair damage. This comprehensive guide will delve into the intricacies of mixing 30 and 20 volume developers, exploring the potential benefits, risks, and best practices.

Understanding Hair Color Developers

Before diving into the specifics of mixing 30 and 20 volume developers, let's establish a foundational understanding of what developers are and how they function. Hair color developers, also known as hydrogen peroxide, are oxidizing agents that lift the hair cuticle, allowing the color molecules to penetrate the hair shaft. The volume number (e.g., 20 volume, 30 volume) represents the concentration of hydrogen peroxide, directly impacting its lifting power.

• Lower Volume Developers (e.g., 10, 20 volume): These developers provide a gentle lift, ideal for subtle color changes, toning, or refreshing existing color. They cause minimal damage and are suitable for sensitive scalps or delicate hair.

• Higher Volume Developers (e.g., 30, 40 volume): These developers offer a more significant lift, capable of lightening hair multiple shades. However, they carry a higher risk of damage and should be used with caution, particularly on previously processed or chemically treated hair.

The Potential Benefits of Mixing 30 and 20 Volume Developers

Mixing 30 and 20 volume developers is sometimes employed to achieve a customized level of lift and processing time. The primary reason for this approach is to tailor the developer strength to the specific needs of the hair and desired outcome.

• Customization: By blending different volumes, you can achieve a lift level somewhere between the strength of a pure 20 volume and a pure 30 volume. This is particularly valuable when aiming for a subtle lift or when working with hair that is already processed. It allows for a more controlled and gradual lightening process, minimizing potential damage.

• Reduced Processing Time: In some cases, mixing can lead to a faster processing time. A lower concentration of peroxide can sometimes be more efficient in lifting certain pigments than a higher concentration alone, leading to faster results while still managing damage risks. This should, however, be monitored closely to avoid over-processing.

• Reduced Risk of Damage (with careful consideration): While higher volume developers inherently carry a greater risk of damage, blending with a lower volume developer can mitigate some of these risks, especially when working with delicate or damaged hair. This approach requires careful calculation and observation.

The Risks of Mixing 30 and 20 Volume Developers

Despite the potential benefits, mixing 30 and 20 volume developers also presents several risks that must be carefully considered.

• Unpredictable Results: The exact lift achieved by a custom mix isn't always predictable. The final result can be influenced by various factors, including the hair's porosity, previous chemical treatments, and the specific hair color product being used. This unpredictability can lead to uneven lightening or unexpected color results.

• Increased Risk of Damage (if not properly managed): While mixing may seem like a way to reduce damage, improper mixing or application can actually increase the risk. Over-processing can still occur, leading to breakage, dryness, and other hair damage. Careful monitoring of processing time is essential.

• Difficulty in Achieving Desired Results: Achieving a specific lift level with a custom mix can be more challenging than using a standard developer volume. Precise measurements and a thorough understanding of developer chemistry are necessary.

Best Practices for Mixing 30 and 20 Volume Developers (If You Choose to Do So)

If you decide to proceed with mixing 30 and 20 volume developers, adhering to these best practices is crucial to minimizing risks and maximizing the chances of success:

• Precise Measurements: Use a precise measuring tool (e.g., a measuring cup or scale) to ensure accurate proportions of each developer. Avoid eyeballing measurements. A common starting point is a 50/50 mix, adjusting based on hair condition and desired lift.

• Thorough Mixing: Mix the developers thoroughly to ensure even distribution. Use a non-metallic bowl and applicator brush to avoid unwanted chemical reactions.

• Strand Test: Always perform a strand test before applying the mixture to the entire head of hair. This allows you to assess the lift, processing time, and overall effect on a small section of hair.

• Close Monitoring: Carefully monitor the processing time. Check the hair regularly to prevent over-processing. The timing will likely be longer than when using a 30 volume developer alone.

• Proper Application: Apply the mixture evenly to avoid patchy results. Follow the instructions on your chosen hair color product carefully.

• Aftercare: Use deep conditioning treatments and moisturizing products to repair and protect the hair after coloring.

Alternatives to Mixing Developers

Before considering mixing developers, explore these alternative approaches which might yield safer and more predictable results:

• Using a Lower Volume Developer: If a gentle lift is desired, opting for a lower volume developer (like 20 volume) directly will eliminate the risk of mixing and ensure a more predictable outcome.

• Multiple Application Sessions: For a more significant lift, instead of mixing higher-volume developers, consider multiple applications of a lower-volume developer. This allows for gradual lightening, minimizing the risk of damage.

• Professional Consultation: The safest approach for significant color changes or complex techniques is to consult a professional hairstylist. They possess the expertise and experience to assess your hair’s condition and provide the best recommendations for achieving your desired color without compromising hair health.

Frequently Asked Questions (FAQs)

Q: Can I mix 30 and 20 volume developers with any hair color?

A: No, the suitability of a mixed developer depends on the specific hair color product and its instructions. Some hair colors are formulated to work optimally with specific developer volumes. Always refer to the product instructions.

Q: What happens if I mix too much 30 volume?

A: Mixing too much 30 volume developer can result in over-processing, leading to hair breakage, dryness, and potentially even hair damage beyond repair.

Q: What is the ideal ratio for mixing 30 and 20 volume developers?

A: There isn't a universally ideal ratio. It depends on your hair’s condition, desired lift, and the specific hair color product being used. A 50/50 mix is a common starting point for experimentation, but a strand test is crucial.

Q: Can I use a mixed developer on previously colored hair?

A: Yes, but exercise extreme caution. Previously colored hair is more fragile and susceptible to damage. A strand test is essential, and a lower volume developer or a professional consultation is highly recommended.

Conclusion

Mixing 30 and 20 volume developers can offer a degree of customization for hair coloring, but it's a technique that carries inherent risks. The unpredictability of results and the potential for damage should be carefully considered. A thorough understanding of developer volumes, precise measurements, and careful monitoring are essential if you choose to proceed with mixing. However, in most cases, using a single volume developer or consulting a professional hairstylist is a safer and more reliable approach for achieving your desired hair color. Always prioritize the health of your hair. Remember, healthy hair is beautiful hair.
