Performing a sensitivity test beforehand is the most effective way to avoid client sensitivity reactions during waxing. This test allows a cosmetologist to apply a small amount of wax on a less sensitive area of the client's skin to see how the skin reacts before proceeding with the full treatment. It helps to identify any potential allergic reactions or sensitivity issues the client may have towards the wax or any of its components. This method prioritizes client safety and comfort, ensuring the chosen products are well-tolerated.

In contrast, while using a pre-wax oil can help to minimize irritation by providing a barrier, it does not guarantee that the client will not have a reaction to the wax itself. Ensuring the wax is very hot is not advisable, as overly heated wax can actually increase the risk of burns or discomfort rather than reduce sensitivity. Applying a soothing lotion afterward can certainly help to calm the skin following the procedure, but it does not prevent the initial sensitivity reaction from occurring during the waxing itself. Hence, testing sensitivity beforehand stands out as the most proactive measure in this scenario.
