Final answer:
The results of a waxing service generally last four to six weeks.
Step-by-step explanation:
The results of a waxing service generally last four to six weeks. This is because waxing removes hair from the root, so it takes longer for the hair to grow back compared to shaving, which cuts the hair at the surface of the skin. Additionally, regular waxing can lead to hair becoming finer and sparser over time, meaning the results may last even longer with continued waxing.
