If you use heavy products that contain oils, silicones, and film formers, it may be necessary to apply a clarifying, purifying, or detoxifying shampoo prior to application, instead of a regular shampoo, to remove buildup from these products for best results. This is due to the accumulation of products that make them act as a barrier.
