[edit] History
Matt Elliott got Procter & Gamble researchers to start making a new anti-dandruff shampoo in 1950. Nearly a decade of research went into making a new formula, which introduced pyrithione zinc into the shampoo.[citation needed]
Head & Shoulders was first introduced to the U.S. market in November 1961 as a blue-green shampoo formula.
