As part of my advice to clients I always give them a list of the most common mistakes people make when they are entering into the beauty business. In fact, I have found many of these mistakes often apply to any category of start up businesses. Over the years I have been observing people that have become successful in the beauty business, there were so many different ways they went about achieving success but when it came to the mistakes along the way, they seem to all share a number of the same ones.
