When should the edges of hot wax be lifted in preparation for removal?

The correct choice emphasizes lifting the edges of the hot wax when it is beginning to set and is flexible. This is crucial for achieving an effective removal. At this stage, the wax is still malleable enough to allow for a comfortable grip without risking damage to the skin or causing unnecessary discomfort. If the wax is lifted too early, it may not adhere effectively to the hair, resulting in an ineffective removal process. Conversely, if the wax has completely dried, it can become too rigid, making it difficult and painful to remove, and potentially damaging to the skin.

Lifting the edges while the wax is still flexible ensures that the hairs are effectively encapsulated, leading to a smoother pull during removal and minimizing the risk of breaking the hair or causing irritation to the skin. Thus, timing is critical in ensuring both efficiency and client comfort during waxing.
