Whats all this about applying oil to the skin before waxing? I was always told to remove any oily residues prior to waxing as the wax won't stick properly and you end up waxing over the area twice to get all the hairs out. I know its to stop the wax fron sticking to the hairs rather then the skin but does it really work? I have been waxing bods for 11 years and have only heard about this recently L x
