Should hair color be applied if the patch test shows a positive result?

A positive result from a patch test indicates that the individual has experienced an allergic reaction or sensitivity to the hair color product being used. Therefore, it is crucial to avoid applying the hair color if the patch test is positive. The patch test is designed to detect potential allergies or irritations before the actual application of hair color, ensuring the safety of the client.

By applying the hair color only if the patch test is negative, you minimize the risk of adverse reactions such as severe itching, burning, swelling, or even more serious complications. This cautious approach is essential in maintaining client safety and trust in color services.
