Shaving stuff includes products such as FOAM, FOAMS, and GEL. FOAM is a four-letter word used to describe a light, airy substance made up of tiny bubbles of gas in a liquid or solid. FOAMS are five-letter words that refer to a mass of small bubbles formed in or on the surface of a liquid. GEL is a three-letter word used to describe a thick, jelly-like substance that does not flow freely. All of these products are used in shaving to help reduce friction and provide a smoother shave.
