Planning For July Special

I found a new interesting ingredient that I want to play with.....Here is what the supplier says

With its soothing properties and rich silica content, Oat Straw Powder makes an excellent addition to both hair and skin products. When used in shampoos, hair conditioners, rinses, and hair masks, Oat Straw imparts a softness and shine that your hair will love. It can also soothe itchy or irritated scalps. In skin care products, Oat Straw acts as a calming agent, making it great for sensitive skin formulations.

Should I do a shampoo or soap???? or both
