Dala, I get waxed every 5 to 6 weeks. I go to a place that uses a hard wax. The hard wax hardens on your skin and then is pulled off, taking the hair with it. The soft wax needs the muslin strips applied on top to stick to the wax.
Don’t go by The 40 Year Old Virgin. There is a bit of a sting when you get waxed, like pulling a band-aid off a hairy arm. It lasts a few seconds and fades. I found the soft wax to be more troublesome, particularly in areas of more flexible skin like the stomach or upper thighs, because the skin pulls with the wax. The hard wax will just pull away from the skin (not pull the skin), even on the stomach or thighs.
