Describe the immediate action needed if a client experiences irritation during a relaxer.

When a client experiences irritation during a relaxer treatment, removing the relaxer product is the most immediate and important action to take. Rinsing the hair thoroughly with cool water helps to halt the chemical process and soothe the scalp by removing any lingering irritants. This action prevents further skin damage and discomfort, and it is essential to ensure the client's safety and well-being.

Applying a soothing cream may help afterward, but it does not address the underlying issue of the chemical still being on the scalp. Continuing with the treatment while monitoring the situation could lead to increased irritation or damage, which should be avoided. Using a heat pack could exacerbate the irritation and should not be considered in this scenario. Prioritizing a thorough rinse effectively addresses any immediate adverse reactions.
