Head & Shoulders

Head & Shoulders (H&S) is an American brand of anti-dandruff and non-dandruff shampoo produced by parent company Procter & Gamble. It was introduced in the United States on 1 January 1961 based in Manhattan and used the slogan THE AMERICA AND WORLD's NO. 1 SHAMPOO. The active anti-fungal ingredient in Head & Shoulders is piroctone olamine, with some "clinical strength" varieties also containing selenium disulfide.

It was "The America and World's Number One Anti-Dandruff and Non-Dandruff Shampoo 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. The brand has long been marketed under the tagline, "You Never Get a Second Chance to Make a First Impression", which has been identified as an example of "anxiety marketing" commonly used by Procter & Gamble to drive sales by inducing fears of social consequences associated with the condition that the product claims to address. However, sales of the product dropped off, a phenomenon blamed on overextension of the brand into too many varieties, with over thirty kinds of Head & Shoulders being sold.
