Developer contains hydrogen peroxide, which breaks down the colour molecules, enabling them to bind to the hair.
The Importance of Developer in Hair Colour
Developer plays a vital role in the hair colouring process, and its importance cannot be overstated. Here are a few reasons why developer is essential:
- Activates the colour formula: Developer activates the colour formula, allowing it to penetrate the hair shaft and produce the desired results.
- Opens up the hair cuticle: Developer helps to open up the hair cuticle, allowing the colour molecules to penetrate the hair shaft.
- Enhances colour deposit: Developer enhances colour deposit, ensuring that the colour is evenly distributed throughout the hair.
Types of Developers
There are several types of developers available, each with its own unique characteristics and uses. Here are a few of the most common types of developers:
Volume Developers
Volume developers are the most commonly used type of developer. They are available in various volumes, ranging from 10 to 40. The volume of the developer refers to the amount of hydrogen peroxide it contains.
- 10 volume developer: 10 volume developer is the lowest volume developer available. It contains 3% hydrogen peroxide and is used for depositing colour only.
- 20 volume developer: 20 volume developer is the most commonly used developer. It contains 6% hydrogen peroxide and is used for most colour applications.
- 30 volume developer: 30 volume developer contains 9% hydrogen peroxide and is used for lifting the hair up to 3 levels.
- 40 volume developer: 40 volume developer contains 12% hydrogen peroxide and is used for lifting the hair up to 4 levels.
Oil-Based Developers
Oil-based developers are used for specific colour applications, such as bleaching or high-lift colouring. They contain a higher amount of hydrogen peroxide than volume developers and are used for more intense colour applications.
Mixing Colour with Developer: The Ideal Ratios
The ideal colour-to-developer ratio varies depending on the hair type, desired outcome, and type of colour being used. Here are a few general guidelines for mixing colour with developer:
Virgin Hair
For virgin hair, the ideal colour-to-developer ratio is 1:1 or 1:2. This means that for every 1 part of colour, you should use 1 or 2 parts of developer.
Coloured Hair
For coloured hair, the ideal colour-to-developer ratio is 1:1 or 1:1.5. This means that for every 1 part of colour, you should use 1 or 1.5 parts of developer.
Bleaching or High-Lift Colouring
For bleaching or high-lift colouring, the ideal colour-to-developer ratio is 1:2 or 1:3. This means that for every 1 part of colour, you should use 2 or 3 parts of developer.
Factors Affecting the Colour-to-Developer Ratio
Several factors can affect the colour-to-developer ratio, including:
Hair Porosity
Hair porosity refers to the hair’s ability to absorb and retain moisture. Hair with low porosity may require a higher volume developer to achieve the desired results.

What is the importance of mixing colour with developer in hair colouring?
Mixing colour with developer is a crucial step in the hair colouring process. The developer helps to activate the colour, allowing it to penetrate the hair shaft and achieve the desired shade. Without the developer, the colour would not be able to bind to the hair, resulting in a dull, uneven colour. By mixing the colour with the developer, you can achieve a more vibrant, long-lasting colour that looks healthy and natural.
Furthermore, the developer helps to break down the colour pigment, allowing it to penetrate the hair shaft more easily. This results in a more even colour distribution, reducing the risk of banding or uneven colour. By mixing the colour with the developer, you can achieve a more professional-looking colour that lasts longer and requires less maintenance.
What are the different types of developers available, and how do they differ?
There are several types of developers available, each with its own unique characteristics and uses. The most common types of developers are 10 volume, 20 volume, and 30 volume. The volume of the developer refers to the amount of hydrogen peroxide it contains, with higher volumes containing more hydrogen peroxide. 10 volume developers are typically used for depositing colour, while 20 volume developers are used for lifting the colour by one to two shades. 30 volume developers are used for lifting the colour by three to four shades.
In addition to the volume, developers can also be classified as either oil-based or cream-based. Oil-based developers are typically used for dry or damaged hair, as they help to moisturize and nourish the hair. Cream-based developers are used for normal to oily hair, as they help to control the amount of moisture in the hair.
