You should immediately wash the hair after applying the toner. Shampoo and conditioner should be used after you rinse the toner.
While some sources recommend waiting 24 hours before shampooing after applying toner, it is important to follow the manufacturer's instructions for the specific toner product you are using.
Important considerations:
- Toner type: If the toner is a permanent hair color, then it is best to shampoo after rinsing it out.
- Manufacturer's instructions: The manufacturer's directions for the specific toner product you are using will provide the most accurate information on whether or not to shampoo after application.
Remember: It is crucial to follow the instructions on the toner product to ensure optimal results and prevent any damage to your hair.
