Clients may be unsure about the timing and scheduling of multiple treatments, such as whether they can receive a facial and waxing on the same day or how to space out different services. It’s important to guide clients on how to sequence treatments to avoid irritation or reduced effectiveness. For example, advising clients to schedule waxing before facials or chemical peels, or suggesting they wait a certain number of days between different treatments, can help prevent adverse reactions and ensure the best possible results from each service.
