I'm confused... I see a set of 15 shampoos, this is not what I'm used to how does this work?

No apologies for the untypical-ness of stating precisely 'what works' here. The 'palette' of these 15 different shampoos contains all the different properties and principals you need to help get the amazing results that we do. Louise Marie arranges them for you, and prescribes from them. She arranges them in an order that is best for you. First we test you when you get your kit, then Louise Marie lines up their order for you, you don't need to worry about what to do why or when with this set of shampoos.
