The ratio of developer to hair dye is crucial for achieving desired color results. A 20 volume developer, containing a 6% concentration of hydrogen peroxide, is a standard choice for many coloring processes. Typically, a 1:1 ratio of hair color to developer is recommended, meaning equal parts of color and 20 volume developer are mixed. However, some manufacturers or specific coloring techniques may require different ratios, so always consult the product instructions. For example, high-lift colors or applications seeking significant lightening might call for a 1:2 ratio, using twice as much developer as color.
Correctly proportioning developer and hair color is essential for predictable and satisfactory results. Using the proper ratio ensures the color develops correctly, achieving the target shade while minimizing damage. Historically, achieving consistent color results was challenging. Modern developers, with standardized concentrations like 20 volume, have greatly improved the predictability and safety of hair coloring. Understanding the developer’s role in the coloring process allows for greater control over the final outcome, enabling users to achieve the desired lift and deposit of color effectively.
This fundamental principle of hair coloring underpins various techniques and considerations. Topics such as selecting the correct developer volume for different hair types and desired lift levels, understanding the chemical process involved, and recognizing potential issues arising from incorrect ratios will be further explored.
1. Ratio
The ratio of developer to hair color is fundamental to achieving predictable color results. An incorrect ratio can lead to undesirable outcomes, ranging from uneven color to hair damage. Understanding this core principle is essential for successful hair coloring.
-
Standard Ratio (1:1)
The most common ratio is 1:1, meaning equal parts developer and hair color. This ratio is often recommended for standard coloring processes, such as depositing color or covering gray. For example, if using 30ml of hair color, 30ml of 20 volume developer would be required. This balanced ratio ensures optimal color development and predictable results.
-
Higher Developer Ratio (1:2)
Some applications, such as high-lift colors, require a higher ratio of developer. A 1:2 ratio, with twice as much developer as color, provides greater lifting power. This is necessary when significantly lightening the hair. For instance, if using 30ml of high-lift color, 60ml of 20 volume developer would be necessary. This increased concentration of peroxide facilitates greater lightening.
-
Lower Developer Ratio (2:1)
While less common, certain situations may call for a lower developer ratio. This might involve depositing color on already lightened hair or toning. A 2:1 ratio, meaning twice as much hair color as developer, can provide more pigment deposit with less lift. For example, if using 30ml of toner, 15ml of 20 volume developer would be used.
-
Manufacturer Recommendations
It’s crucial to consult the manufacturer’s instructions for the specific hair color being used. Recommendations may vary depending on the product formulation and desired result.

2. Hair Type
Hair type significantly influences the effectiveness of 20 volume developer and, consequently, the amount required to achieve desired color results. Factors such as hair porosity, texture, and existing color play a crucial role in determining how the hair will react to the developer. Understanding these factors allows for tailored application strategies and predictable outcomes.
Porosity refers to the hair’s ability to absorb moisture. Highly porous hair absorbs and releases moisture quickly, requiring less developer to achieve lift. Conversely, low porosity hair requires more developer due to its resistance to absorption. For example, chemically treated or damaged hair tends to be more porous, while virgin hair typically exhibits lower porosity. Texture also affects developer efficacy. Fine hair processes color more quickly than coarse hair, often requiring less developer to achieve the desired lift. Coarse hair, with its larger diameter, necessitates a greater amount of developer for effective color penetration and development. Existing hair color impacts the necessary developer volume. Darker hair requires more lift to achieve lighter shades, often necessitating a higher developer concentration or a longer processing time compared to lighter hair.
Careful consideration of hair type before color application is paramount. Accurately assessing porosity, texture, and existing color enables appropriate developer adjustments, minimizing the risk of undesirable outcomes such as uneven color, excessive lift, or hair damage. This informed approach leads to consistent, predictable color results tailored to individual hair characteristics.
3. Desired Lift
The desired lift, or the number of levels lighter one aims to achieve, directly correlates with the amount of 20 volume developer necessary. Understanding this relationship is paramount for achieving predictable color results and preventing unintended consequences such as over-processing or insufficient lightening.
-
Minimal Lift (1-2 Levels)
For subtle lightening or depositing tone on already lightened hair, minimal lift is required. In such cases, a standard 1:1 ratio of 20 volume developer to hair color is often sufficient. This allows for gentle lightening or color deposit without drastic changes. For instance, refreshing highlights or adding a toner typically falls within this range. Using more developer than necessary for minimal lift can result in unwanted brassiness or damage.
-
Moderate Lift (2-3 Levels)
Achieving a moderate lift requires a slightly higher concentration of peroxide. While a 1:1 ratio may suffice for some hair types, others might benefit from a slightly higher ratio of developer. This is particularly true for coarser or more resistant hair. An example would be lifting a medium brown shade to a light brown. Careful monitoring of the development process is crucial to avoid over-processing.
-
Significant Lift (3-4 Levels)
Lifting hair three to four levels lighter necessitates more developer. A 1:2 ratio, meaning twice as much developer as color, is often recommended. This increased concentration provides the necessary lift for achieving lighter shades. Transitioning from dark brown to light blonde, for example, falls into this category. However, this level of lift carries a higher risk of damage and requires meticulous application and monitoring.
-
Maximum Lift (4+ Levels)
Achieving maximum lift, such as transitioning from black to blonde, requires significant lightening power and careful consideration. High-lift color products specifically designed for this purpose, combined with 20 volume developer, are typically employed. Multiple applications might be necessary, with appropriate conditioning treatments between sessions to minimize damage. This level of lift demands expertise and caution to avoid compromising hair health.
Accurately assessing the desired lift and tailoring the developer ratio accordingly is essential for achieving predictable, desirable color results while minimizing potential damage.
