What is the primary reason to advise clients against sun exposure before hair removal treatments?

Advising clients against sun exposure before hair removal treatments primarily revolves around the risk of skin irritation and complications. When skin is exposed to the sun, it may undergo a series of changes, including increased sensitivity and potential for sunburn. Intense sun exposure can cause the skin to become inflamed or damaged, which can complicate hair removal procedures. The integrity of the skin is crucial for effective hair removal, as damaged skin can lead to adverse reactions such as redness, swelling, or even scarring post-treatment.

Furthermore, sunburned or tanned skin is more susceptible to pain during hair removal and can lead to uneven results, or worse, chronic skin issues. Thus, avoiding sun exposure ensures that the skin remains in the best possible condition for the treatment, ultimately minimizing risks and promoting optimal results.
