Toner is typically mixed with developer to activate its color and allow it to deposit onto the hair.
Here's a more detailed explanation:
-
The Purpose of Developer: Developer contains hydrogen peroxide, which opens the hair cuticle, allowing the toner to penetrate and neutralize unwanted undertones (like brassiness) or deposit desired color.
-
Mixing Ratio: The most common mixing ratio for toner and developer is 1:2 (one part toner to two parts developer). However, always refer to the specific instructions provided by the toner manufacturer, as ratios can vary.
-
Application: After mixing, the toner and developer should be applied to the hair using an applicator brush. Focus on areas with unwanted undertones.
-
Processing Time: Processing time varies depending on the specific toner and desired results. Usually, it's left on for up to 45 minutes, but again, always follow the product instructions.
-
After Toning: After the processing time is up, rinse the hair thoroughly, then shampoo and condition with moisturizing products.
Importance of Following Instructions:
Using the correct developer volume and mixing ratio is crucial for achieving the desired results and avoiding damage to the hair. Too high a developer volume can cause damage and unwanted lightening, while too low a volume might not effectively activate the toner.
