Which of the following precautions is essential during a waxing procedure?

Checking the temperature of the wax is essential during a waxing procedure because it ensures the safety and comfort of the client. Wax that is too hot can cause burns and skin irritation, while wax that is too cold may not adhere properly to the hairs, making the waxing process less effective. Proper temperature control allows for optimal performance of the wax and minimizes the risk of adverse reactions, ensuring a smooth and safe experience for the client. This precaution is part of good practice in the beauty industry, where client safety and satisfaction are paramount.
