As a hair professional, understanding how to work with different developer volumes is crucial for achieving the desired results in hair coloring, bleaching, and other chemical treatments. The volume of the developer refers to its strength, measured in terms of the amount of hydrogen peroxide it contains, which is crucial for lifting the hair color. In some cases, you might need to adjust the volume of your developer to suit the specific needs of your client’s hair. This article will delve into the process of making 30 volume developer from 40 volume, providing you with a detailed guide on how to do it safely and effectively.
Understanding Developer Volumes
Before we dive into the conversion process, it’s essential to understand what developer volumes mean and how they’re used in hair coloring and bleaching. Developer volumes are categorized based on their percentage of hydrogen peroxide, which ranges from 10 volume (3%) to 40 volume (12%). The choice of developer volume depends on the desired lift and the condition of the client’s hair. For instance, 10 volume developers are used for minimal lift and to deposit color, while 40 volume developers are used for significant lift and are often utilized in bleaching processes.
The Role of 30 Volume Developer
A 30 volume developer, containing 9% hydrogen peroxide, is considered a high-lift developer. It’s used for applications where a significant color change is desired but might be too harsh for damaged or over-processed hair. 30 volume developers are ideal for achieving 3-4 levels of lift, making them versatile for various coloring and highlighting techniques. Understanding the role and application of 30 volume developer is crucial for deciding when to convert a 40 volume developer to a 30 volume.
Converting 40 Volume to 30 Volume Developer
Converting a 40 volume developer to a 30 volume involves diluting the 40 volume developer with a lower volume developer or a conditioning treatment. The most common method is to mix the 40 volume developer with a 10 volume developer. However, it’s crucial to follow a precise ratio to achieve the desired concentration. The general rule of thumb for diluting developer is based on the desired volume and the volumes you are working with.
To convert 40 volume to 30 volume, you can use the following dilution method:
– Start with the amount of 40 volume developer you need for your application.
– Calculate the amount of 10 volume developer needed to dilute the 40 volume developer to achieve a 30 volume concentration.
The formula for dilution can be complex, but a simplified approach is to remember that to go down one volume, you need to add an equal part of the lower volume developer. However, since we are going from 40 volume to 30 volume, which is a decrease of 10 volumes, the calculation involves determining how much of the 40 volume developer to mix with a 10 volume developer to achieve the desired strength.
Calculation Example
Let’s say you need 3 ounces of 30 volume developer for your application. To achieve this from a 40 volume developer, you would mix it with a 10 volume developer. A common ratio might involve using 2 parts of 40 volume developer to 1 part of 10 volume developer, but this can vary based on the exact formulation of the developers you’re using and the desired outcome.
Given the complexity of developer chemistry, it’s always recommended to consult the manufacturer’s guidelines for the specific products you are using, as different brands may have slightly different concentrations of hydrogen peroxide even within the same volume category.
Safety Precautions and Considerations
When working with hair developers, especially when converting between volumes, safety should always be your top priority. Here are some key considerations:
- Always wear protective gear, including gloves and goggles, when handling developers to prevent skin and eye irritation.
- Perform a strand test before applying any chemical treatment to the entire head to ensure the desired results and to check for any adverse reactions.
- Follow the instructions carefully and never leave the treatment on for longer than recommended, as this can cause damage to the hair and scalp.
- Be aware of the condition of the client’s hair and adjust your treatments accordingly. Damaged or over-processed hair may require lower volume developers to prevent further damage.
