If you use 10 volume developer with toner, the result will depend on the specific toner shade and the desired outcome. Generally, 10 volume developer is considered a lower strength developer, which means it will deposit less color onto the hair compared to a higher volume developer.
When using a toner, the developer is responsible for activating the color molecules in the toner and allowing them to penetrate the hair shaft. The volume of the developer determines how effectively the color molecules are deposited and how long the color will last.
Using a 10 volume developer with toner can be beneficial if you want a subtle or more natural-looking result. It is also suitable for toning already lightened hair or neutralizing unwanted brassy or yellow tones. Since it is a lower volume developer, it will deposit less color and provide a more gentle effect on the hair.
However, if you are looking for a more dramatic or intense result, using a 10 volume developer may not be sufficient. In this case, you may need to opt for a higher volume developer, such as 20 volume or even 30 volume, depending on the desired outcome.
It is important to note that the specific instructions and recommendations provided by the toner manufacturer should be followed for best results. They will often specify the recommended developer volume to be used with their toner.
To mix the toner and developer, you will typically use equal parts of each. For example, if you have 1 oz. of toner, you would mix it with 1 oz. of 10 volume developer. This ratio ensures proper color development and balance.
Using a 10 volume developer with toner can result in a more subtle or natural-looking color, especially for toning or neutralizing unwanted tones. However, if you are aiming for a more intense or dramatic result, a higher volume developer may be necessary. Always follow the instructions provided by the toner manufacturer for best results.
