What should be done prior to performing a chemical service?

Conducting a consultation and a patch test prior to performing a chemical service is essential for several reasons. The consultation allows the cosmetologist to assess the client's hair type, condition, and any specific needs or concerns they may have regarding the service. This step is crucial because it helps the stylist determine the appropriate products and techniques to use, ensuring the best possible outcome for the client's hair.

Performing a patch test is equally important as it helps to identify any potential allergic reactions the client might have to the chemical products being used. This test typically involves applying a small amount of the chemical product to a discreet area of the skin and monitoring for any adverse reactions over a specific time period. If the client shows no reaction, it indicates that it is generally safe to proceed with the chemical service.

In contrast, applying the chemical directly to the hair without proper assessment and testing can lead to damaging effects or adverse reactions. Washing the hair thoroughly might be required in some situations, but it does not replace the necessity of understanding the client's hair and ensuring safety through consultation and patch testing. Similarly, trimming the hair ends is a consideration for overall hair health, but it is not specifically related to the safety and effectiveness of performing a chemical service.
