What is the difference between 20 and 30 volume developer? This is a common question among individuals who are new to hair coloring or styling. The volume of a developer is a crucial factor that determines the strength and effectiveness of the chemical reaction between the developer and the hair dye. Understanding the differences between these two volumes can help you choose the right product for your specific hair needs.
The primary difference between 20 and 30 volume developer lies in their ability to lift the natural color of the hair. A 20 volume developer is a mild lifting agent, typically used for coloring hair that is already lightened or for a subtle color change. On the other hand, a 30 volume developer is a stronger lifting agent, ideal for bleaching dark hair or achieving a significant color change.
Here are some key points to consider when comparing the two:
1. Lift Ability: As mentioned earlier, a 30 volume developer is more potent in lifting the natural color of the hair compared to a 20 volume developer. This means that a 30 volume developer can lighten hair more effectively, especially if you’re starting with dark hair.
2. Processing Time: Since a 30 volume developer is stronger, it may require a shorter processing time compared to a 20 volume developer. However, it’s essential to follow the instructions on the product to avoid over-processing, which can lead to damage.
3. Damage Risk: Due to its stronger formula, a 30 volume developer poses a higher risk of hair damage. It’s crucial to use a 30 volume developer with caution and ensure that your hair is healthy and well-moisturized before applying it.
4. Results: The results achieved with a 30 volume developer will generally be more dramatic and long-lasting compared to a 20 volume developer. However, the extent of the color change will depend on your starting hair color and the specific hair dye you’re using.
5. Cost: Generally, a 30 volume developer is more expensive than a 20 volume developer due to its stronger formula and the potential for more noticeable results.
In conclusion, the main difference between 20 and 30 volume developer lies in their lifting ability, processing time, risk of damage, and the final results. It’s essential to choose the right volume based on your hair type, desired outcome, and the condition of your hair. If you’re unsure, it’s always a good idea to consult with a professional hair stylist to ensure the best results and minimize the risk of damage.
