Beyond Brazilian waxes, Dr. Oz has an even bigger question. "Do you ever sit back at night and think, 'Why do I have pubic hair?'"
Dr. Oz has two conclusions. "It prevents chafing. It actually lubricates the skin folds that are moving over each other," he says, but removing the hair doesn't usually lead to chapped skin. "The other more important reason is it's actually a bigger place for the pheromones to sit, the chemicals that you normally secrete that your loved one is actually liking."
