Head & Shoulders (H&S) is an American brand of anti-dandruff and non dandruff shampoo produced by parent company Procter & Gamble that was introduced in 1961. By 1982, it was the "number one brand" of shampoo, and it was noted that "(n)o one hair care brand gets so many ad dollars as Head & Shoulders, a twenty year old brand, and no other brand matches its sales", despite it being a "medicated" shampoo.
