Which of the following is a benefit of waxing?

Waxing provides the advantage of longer-lasting results compared to shaving. When hair is removed from the root during waxing, it takes longer for the hair to grow back than when shaving, which only cuts the hair at the surface level. This process leads to a smoother appearance for a longer period, as the hair follicles are removed entirely from the skin rather than just trimmed.

The fact that waxing results in the hair growing back more slowly can also lead to finer and softer hair regrowth over time, enhancing the overall smoothness after multiple wax treatments. Thus, this characteristic makes waxing a preferred method of hair removal for people looking to maintain their smooth complexion for an extended duration.

Other options do not accurately present the facts about waxing: it's not completely painless, it's not designed to encourage hair regrowth, nor is it restricted only to sensitive skin types.
