With first time clients,  I am very careful to clarify what I understand to be the issue they are having and the outcome they are seeking.  I ask about habits and whether they have any allergies.  I let them know that I want them to choose the product that is best for them and will provide the outcome they are seeking.  I walk them through the ordering process and let them know when they can expect to receive their products.  I don't know whether other consultants cover all of that information or not, as we are all independent.
