Performing patch tests is critical in ensuring that clients do not have allergic reactions to hair color products. The guideline for conducting patch tests is to perform them 48 hours before the application of hair color. This timeframe allows for adequate observation of any potential allergic reactions to occur within the window, ensuring the safety and comfort of the client during the actual hair coloring process.

By conducting the test 48 hours prior, the hairdresser provides enough time to monitor any irritations or adverse reactions, which could be detrimental if the hair color is applied without prior knowledge of the client's sensitivity to the product. If a reaction occurs during this testing period, the stylist can recommend alternative products or methods to ensure the client’s safety, allowing for a more personalized and responsible approach to hair treatment.
