What is the recommended way to handle a client with a previous allergic reaction?

When dealing with a client who has a history of allergic reactions, the best practice is to discuss alternative products and perform a patch test. This approach prioritizes the client's safety and well-being by ensuring that any products used during the service will not trigger a reaction.

By discussing alternative products, you can identify formulations that are less likely to cause issues based on the client’s previous reactions. Additionally, a patch test allows for a small application of the product on the client’s skin, which helps to gauge their sensitivity and tolerance before applying it more broadly during the service. This method is thorough and minimizes the risk of adverse reactions.

Choosing not to perform any service, by delaying it for a later date, might seem cautious but it could also leave the client feeling underserved or anxious about their needs. Simply applying a stronger formula without testing is unsafe and irresponsible, as it can exacerbate allergic reactions. Assuming the client can use any product disregards their previous experiences and can lead to serious consequences. Hence, the recommended approach combines safety, communication, and professional responsibility.
