Before undergoing a waxing treatment, what should clients avoid?

Clients should avoid sun exposure and exfoliating treatments before undergoing a waxing treatment because both can significantly affect the skin's sensitivity and reaction during the waxing process.

Sun exposure can lead to increased skin sensitivity and irritation. When the skin is already compromised by sunburn or damage, waxing can cause more pain and potentially result in skin lifting or damage. Similarly, exfoliating treatments can strip away the outer layer of skin, leaving it more vulnerable and sensitive. This can also lead to further irritation and increase the risk of adverse reactions during waxing.

In contrast, while excessive drinking, wearing heavy makeup, and showering right before a treatment may have some impact, they are less directly related to how the skin responds to waxing and do not pose the same level of risk for skin integrity as sun exposure and exfoliation. Thus, avoiding these two factors helps ensure a safer and more comfortable waxing experience for the client.
