Advise clients to avoid soaking in hot baths or hot tubs for 24-48 hours after treatments like waxing, laser hair removal, or body wraps. Prolonged exposure to hot water can irritate the skin and increase the risk of infection in freshly treated areas. Recommend lukewarm showers as a safer alternative to keep the skin clean without compromising its recovery. This guidance ensures that clients protect their skin while still maintaining good hygiene.
