When it comes to hair coloring, understanding the nuances of developer volumes is crucial for achieving the desired results. One of the most popular developer volumes is 20 volume, which is often used for lifting and depositing color. But how many shades can 20 vol lift? In this article, we’ll delve into the world of hair coloring and explore the capabilities of 20 volume developer.
Understanding Developer Volumes
Before we dive into the specifics of 20 volume developer, it’s essential to understand the basics of developer volumes. Developer volumes, also known as oxidizing agents, are used to activate hair color and help it penetrate the hair shaft. The volume of the developer refers to the amount of hydrogen peroxide it contains, which is measured in percentages.
Developer volumes range from 10 volume to 40 volume, with each volume having a specific lifting capacity. The higher the volume, the more lift it can achieve. However, higher volumes also increase the risk of damage and over-processing.
The Role of 20 Volume Developer
20 volume developer is a popular choice among hairstylists and colorists because it offers a good balance between lift and deposit. It contains 6% hydrogen peroxide, which is sufficient to lift the hair 2-3 shades, depending on the starting color and condition of the hair.
20 volume developer is often used for:
- Lifting and depositing color on virgin hair
- Toning and glossing previously colored hair
- Creating subtle, natural-looking highlights
How Many Shades Will 20 Vol Lift?
The number of shades that 20 vol can lift depends on several factors, including:
- Starting color: 20 vol can lift darker hair more than lighter hair. For example, it can lift dark brown hair 2-3 shades, while it may only lift light brown hair 1-2 shades.
- Hair condition: Damaged or over-processed hair may not lift as well as healthy hair.
- Processing time: The longer the processing time, the more lift can be achieved. However, over-processing can lead to damage and unwanted results.
Generally, 20 vol can lift:
- 2-3 shades on virgin hair
- 1-2 shades on previously colored hair
- 1 shade on damaged or over-processed hair
| Starting Color | Lift Achieved with 20 Vol |
|---|---|
| Dark Brown | 2-3 shades |
| Light Brown | 1-2 shades |
| Blonde | 1 shade |
Factors Affecting Lifting Capacity
While 20 vol can lift 2-3 shades, there are several factors that can affect its lifting capacity. These include:
- Porosity: Hair with low porosity may not lift as well as hair with high porosity.
- Moisture levels: Hair with high moisture levels may not lift as well as hair with low moisture levels.
- Previous color treatments: Hair that has been previously colored or chemically treated may not lift as well as virgin hair.
- Developer-to-color ratio: The ratio of developer to color can affect the lifting capacity of 20 vol.
Tips for Achieving Optimal Lift with 20 Vol
To achieve optimal lift with 20 vol, follow these tips:
- Use the right developer-to-color ratio: A 1:1 or 1:2 ratio is recommended for most applications.
- Choose the right color: Select a color that is formulated for use with 20 vol developer.
- Process for the right amount of time: Processing time will depend on the starting color and desired results. Generally, 20-30 minutes is recommended.
- Use a pre-color treatment: A pre-color treatment can help open up the hair cuticle and allow for better lift.
Common Mistakes to Avoid
When using 20 vol developer, there are several common mistakes to avoid:
- Over-processing: Over-processing can lead to damage, dryness, and unwanted results.
- Under-processing: Under-processing can result in inadequate lift and poor color deposit.
- Using the wrong developer-to-color ratio: Using the wrong ratio can affect the lifting capacity and overall results.
Conclusion
20 vol developer is a versatile and popular choice among hairstylists and colorists. While it can lift 2-3 shades, the actual lifting capacity will depend on several factors, including starting color, hair condition, and processing time. By understanding the basics of developer volumes and following tips for optimal lift, you can achieve professional-looking results with 20 vol developer. Remember to avoid common mistakes and always follow the recommended guidelines for use.
What is 20 volume developer and how does it work?
20 volume developer is a type of hair bleach or color developer that contains 20 volume hydrogen peroxide. It is used to lift the hair color by breaking down the pigment in the hair shaft. The developer works by releasing oxygen molecules that penetrate the hair and break down the melanin, allowing the hair to lighten.
The volume of the developer refers to the strength of the hydrogen peroxide solution. A higher volume developer will lift the hair color more than a lower volume developer. However, using a higher volume developer also increases the risk of damage to the hair, so it’s essential to use it carefully and follow the instructions.
How many shades will 20 volume developer lift?
20 volume developer can lift the hair color by 2-3 shades, depending on the starting color and the condition of the hair. It is a relatively gentle developer that is suitable for most hair types, but it may not be enough to achieve a drastic color change. If you want to achieve a more significant color lift, you may need to use a higher volume developer or repeat the process.
However, it’s essential to note that the number of shades that 20 volume developer can lift also depends on the type of hair you have. If you have virgin hair, you may be able to achieve a more significant color lift than if you have previously colored or damaged hair. It’s always a good idea to do a strand test before applying the developer to your entire head to ensure the desired results.
