One of the first things you need to think about when starting a new business is the costs involved. When it comes to opening a beauty business, a salon of some kind, whether it’s a beautician's, hairstylist's or something else, the cost will depend on location as well as business or rent rates, costs for hiring staff, buying equipment and products and marketing. The cost of opening a high street salon can be anything from £3,000 to £50,000.
