A lot of people who go in for this treatment have ingrown hairs that need to be extracted, and quite possibly some skin irritation from hair removal. Obviously, though, it's always good to be proactive and prevent problems before they start. People with coarse body hair are more prone to ingrowns, so going in for a vajacial a day or two after you shave or wax could potentially keep away any irritation. You can also get the treatment just to pamper yourself, whether you suffer from ingrowns or not!
