What should be done if a chemical hair treatment causes irritation?

If a chemical hair treatment causes irritation, rinsing the hair with water and seeking professional advice is the proper course of action. This approach ensures immediate relief from the irritation by removing the product from the hair and scalp, which helps prevent further damage or adverse reactions. Consulting with a professional allows for an assessment of the situation to determine the best steps moving forward, ensuring the client's safety and well-being.

Continuing with the treatment at a lower strength could exacerbate the irritation, as the underlying issue may not be addressed effectively. Similarly, applying more product to balance the effect could worsen the situation by increasing the chemical exposure, which is unwise in the face of an adverse reaction. Ignoring the irritation and finishing the treatment is highly inadvisable, as it could lead to severe skin reactions or long-term damage. Therefore, rinsing and seeking guidance is the most responsible and protective action to take.
