What should be done if a client's hair shows excessive damage during processing?

When a client's hair shows excessive damage during processing, the appropriate action is to rinse the product immediately. This is crucial because continuing the processing can exacerbate the damage, leading to further weakening of the hair, breakage, and potentially irreversible harm. Rinsing helps to halt the chemical reaction taking place, protecting the integrity of the hair and minimizing additional damage.

Immediate rinsing also prioritizes the client's hair health and safety, ensuring that they do not suffer unnecessary consequences from the treatment. It's essential to monitor the hair's condition throughout any chemical process, and once signs of excessive damage appear, intervention is necessary to mitigate further harm.

In contrast, continuing to process may worsen the situation and applying more product does not address the existing damage. Consulting another professional could be a wise decision after the immediate action of rinsing, but it should not take precedence over stopping the chemical process right away to protect the client's hair.
