How to develop branded hair product line

Today we can see more and more movie or music stars that are promoting their new cosmetic or fashion products with their own branding. They take advantage of their celebrity status and promote their own line of products. Most people think that celebrities can do that only because they have too much money that they can invest and that this is not something that they can do. In the past it was really expensive to make your own product line and to have your own branding. However, today that is possible for almost everyone with a good idea and some money on the side.
