Shower device with multi-product dispensing capability

A two-stage coaxial shower head that allows conventional water flow through the shower head or a mixture of product and water through a product low flow nozzle. The product may be such liquids as soap, moisturizer, shampoo, or hair conditioner. Products are contained within product pressure reservoirs each with a product section and a piston. During a shower, a user rotates a selector dial at the multi-ported spool valve to select a product or conventional water flow for rinsing. When a product is selected water flow through a water supply tube from the multi-ported spool valve to the shower head will cease and pressure to force water down to the lower part of a product reservoir to raise the piston in the product pressure reservoir to reject product that is transported to a shower head section. A version using electronics instead of hydraulics is also presented.
