The amount of time you leave toner on with a 10 developer depends on the desired level of toning and the specific toner formula used. However, a general guideline is to leave it on for 10-20 minutes.
Here are some factors to consider:
- Toner Strength: Stronger toners will require less time to achieve the desired result.
- Hair Condition: Damaged or porous hair will absorb toner faster, requiring less time.
- Desired Level of Toning: A subtle tone may only require a few minutes, while a more dramatic change may need longer.
Important Note: It's crucial to follow the instructions on the toner product label.
Always perform a strand test before applying toner to your entire head of hair to ensure you achieve the desired results and prevent unwanted color changes.
