According to licensed cosmetologist Naomi Torres for About.com, a Brazilian wax will likely be a very uncomfortable experience. The amount of pain a person feels during the process has much to do with the spa technician who is giving the Brazilian wax and the type of wax used.
The reason a Brazilian wax is painful is because thick, coarse hair is being rapidly ripped from the follicles in a very sensitive area of the body. If the spa attendant is new to performing this service and removes the hair in the wrong direction, this could result in serious pain. It is also essential that hard wax is used for a Brazilian wax. It is not sticky and keeps the client from having to get waxed several times to remove hair in the same spot.
