The perfumer will then go through the process of blending multiple mixtures and will attempt to capture the desired feelings specified in the brief. After presenting the perfume mixtures to the customers, the perfumer may "win" the brief with their approval. They proceed to work with the customer, often with the direction provided by a panel or artistic director, which guides and edits the modifications on the composition of the perfume. This process typically spans several months to several years, going through many iterations, and may involve cultural and public surveys to tailor a perfume to a particular market. The composition will then be either used to enhance another product as a "functional fragrance" (shampoos, make-up, detergents, car interiors, etc.) or marketed directly to the public as a "fine fragrance".
