Conducting a patch test to check for sensitivities is a critical safety measure when using chemical relaxers. This procedure involves applying a small amount of the relaxer to a discreet area of the client’s skin, usually behind the ear or on the inner arm, to monitor for any allergic reactions or sensitivities prior to applying the product to the entire scalp and hair. This helps ensure the client's safety and prevents adverse reactions that could occur during a full application, such as burns, irritation, or severe allergic reactions.

Safety is paramount in cosmetology, and ensuring that clients do not have adverse reactions to chemicals is a key part of the process. By performing a patch test, a barber or stylist not only protects their clients but also mitigates liability for potential harm caused by chemical applications. This precautionary step is a standard practice in the industry and underscores the importance of client health and safety in any procedure involving harsh chemicals.

The other options do not prioritize client safety or are counterproductive. Using a higher dosage could lead to more severe reactions, applying relaxers on dry hair may result in uneven application or damage, and avoiding client consultations undermines the trust and understanding necessary for effective and safe service.
