While I have not had my hair done here, they have answered many a product questions for me. What I have had done is waxing. They have done both brows and upper lip for me. On each occasion I have had an adverse reaction and have broken out from either the wax used (which was supposed to be for sensitive skin) or the lotion applied after. When I commented on this they seemed unconcerned. After having both treatments done elsewhere I now know it was whatever they were using, despite the fact they said that wasn’t possible.
