Introduction: In the quest for achieving the perfect hair color, one essential aspect often overlooked is the choice of the right developer. Developers, also known as activators, play a crucial role in hair dyeing processes. They help the color penetrate the hair shaft, making the color change permanent. In this comprehensive guide, we'll explore the differences between 20 and 30 volume developers and help you make an informed decision on which one to use. Let's dive right in.
Understanding Hair Developer Levels Hair developer levels are determined by their oxidizing potential and signify the amount of hydrogen peroxide they contain. The most commonly used hair color and bleach formulas come with developers at 10, 20, 30, or 40 volumes. Each volume has a specific purpose and impact on your hair.
20 Volume Developer: Gentle Yet Effective 20 volume developer is a versatile choice, often used in both permanent and semi-permanent hair colors. It can lighten your natural, undyed hair by one or two shades when used with a permanent color. If you decide to mix 20 volume developer with bleach powder, it can lighten "virgin hair" by approximately five levels. This volume developer is an excellent option for individuals looking for a moderate lift without causing excessive damage to their hair.
30 Volume Developer: The Lifter 30 volume developer is primarily designed for color lifting. It is used for bleaching and can lighten your hair by around seven levels, depending on the type of bleach powder you use. Typically chosen by those with darker hair who aim for a significant lightening effect, 30 volume developer is an excellent choice when handled with care. It can open the door to striking transformations, but it should be used judiciously to avoid excessive damage.
Balancing Act: Mixing 20 and 30 Volume Developers Yes, you can mix 20 and 30 volume developers to achieve a balanced lifting effect. The 20 volume developer will lift your hair by one to two shades, while the 30 volume developer can provide a lift of three to four shades. This mixture allows for precision in your hair coloring journey. However, it's essential to avoid using anything stronger than 30 volume developer when doing this at home, as higher volumes can result in unnecessary damage.
The Importance of Developer in Hair Dye Developers are vital components in achieving the desired hair color. They open the hair cuticle, allowing the color to penetrate and create the desired effect. When it comes to mixing developer with hair dye, getting the proportions right is essential. Too much developer can weaken the color, making it fade faster. Conversely, too little developer can hinder the dye's ability to open the hair cuticle, resulting in an uneven color outcome.
The Impact on Damaged Hair Using developer on damaged hair is generally safe, but precautions should be taken. For instance, when applying 30 volume developer without mixing it with other products, it's essential to test the outcome beforehand. Any lightening process, including the use of developers, may cause damage to your hair. To minimize this, ensure you're performing strand tests and taking measures to maintain hair health.
Shelf Life and Proper Storage Developers have a limited shelf life. It's crucial to check the expiry date, typically indicated on the bottle as 12M or 24M, representing 12 or 24 months. To maximize the effectiveness of your developer, keep the bottle tightly closed and store it in a cool, dark place, away from direct sunlight. Avoid storing it in a warm environment. Additionally, once mixed with bleach or color, developers cannot be saved for later use and should be disposed of properly.
Conclusion In the world of hair coloring, the choice between 20 and 30 volume developers can significantly impact the outcome. Understanding their differences, purposes, and the effects they have on your hair is essential for making an informed decision. Whether you're seeking a subtle change or a dramatic transformation, the right developer can make all the difference. Remember to prioritize hair health, perform strand tests, and follow recommended guidelines for safe and successful hair dyeing. Now, you're well-equipped to embark on your hair coloring journey with confidence.
