What is the purpose of using a spatula during waxing?

Using a spatula during waxing serves the specific purpose of spreading the wax evenly across the area being treated. The spatula allows for a controlled and effective application of the wax, ensuring that it adheres properly to the hair and skin. An even layer of wax is crucial for achieving optimal hair removal, as it ensures that the wax grips the hair effectively when it cools and hardens, making the removal process smoother and more efficient.

While the other options mention actions related to the waxing process, they do not define the primary function of the spatula itself. Removing the wax or hair does not involve the spatula's role, as these actions are performed with different tools or methods after the wax has been applied. Therefore, understanding the spatula's role enhances the overall effectiveness of waxing as a hair removal technique.
