Hello Wax Pot. I am not going to use my real name, but I am an esthetician for many years. I have herpes. I get and do brazilains all the time. I can not remember the last time I did get an outbreak. Even after getting a brazilian on me. I have never have taken any meds for it and I am totally fine. I do know stress can bring them out. I would warn her that it may possibly cause a reaction or it may not and she can take care of it from there.
