Hair regrowth time varies, but on average, it may take a few weeks or months for hair to grow back fully after using One Glide MagicSilk Hair Removal. Individual factors such as genetics, hormone levels, and overall health can influence the rate of regrowth. It's important to note that hair regrowth may occur unevenly or at different rates on different body parts. To avoid any negative skin reactions, we recommend doing a patch test before using the product on a larger area.
