What should the therapist do if the wax dries too quickly?

When wax dries too quickly, moistening it with warm water can help rehydrate the area and allow the wax to become pliable again. This technique is useful because it enables the therapist to remove the wax more easily and comfortably for the client, preventing any discomfort associated with pulling on hardened wax. It reflects an understanding of the need to control the application and removal process for optimal results in waxing practices.

The other choices do not address the issue effectively. Applying more wax over it can lead to uneven results and additional complications because the underlying wax may still be too stiff. Removing it immediately could cause discomfort for the client if the wax has already set, and waiting until it cools doesn't resolve the problem; once the wax has cooled and hardened, it becomes more difficult to manage. Therefore, moistening the area is the most effective and appropriate response to handle wax that has dried too quickly.
