Hi everyone. After a few years of trying to go into some kind of beauty buisness and doing some collage courses and then putting on hold to adopt a couple of kids, I am now (hopefully) on track to setting up a small buisness. I have done Nail Care and Into to Beauty at Collage and am now currently on a waxing course there. I really liked the look of the PHD system and bought one second hand through a private ad to try it out but there were no instructions included and i would like to ask what number on the dial it should be set at for continuous use.. Thanks Alison..
