Final answer:
During hot wax treatments, removal strips should always be pulled in the opposite direction of the hair growth while keeping the skin taut.
Step-by-step explanation:
During hot wax treatments, it is essential to use the correct technique to ensure effective hair removal and minimize discomfort. The removal strips should be pulled in the opposite direction of the hair growth. This means if the hair grows downwards, you should pull the strips upwards towards the ceiling. To perform this correctly, hold the skin taut with one hand, and with the other hand, quickly pull the strip away, staying close and parallel to the skin to avoid any undue pain or irritation.
