Depending on the level of hair growth, hard wax hair removal lasts:

Hard wax hair removal is known for its effectiveness in removing hair from the root, which can lead to longer-lasting results compared to other methods. Typically, when using hard wax, the duration of smooth skin can range from four to six weeks. This period allows enough time for hair to regrow to a length suitable for removal during the next session, usually around 1/4 inch in length. The exact time can vary depending on individual hair growth cycles, skin types, and hormonal factors, but four to six weeks is considered the average timeframe for hair regrowth after a hard wax treatment. This method is particularly effective for coarser hair types, often leading to softer and finer regrowth over time, further contributing to its appeal for those seeking a longer-term solution to hair removal.
