Head & Shoulders is a brand of anti-
dandruff shampoo produced by
Procter & Gamble.Procter & Gamble researchers first decided on making a new anti-dandruff shampoo in
1950, when massive public opinion made it clear that the current products on the market were not helping their scalp problems. Nearly a decade of research went into making a new formula, which introduced the product
pyrithione zinc into a shampoo for the first time.

In
technical analysis, a chart formation in which a
stock price reaches a peak and declines, rises above its former peak and again declines and rises again but not to the second peak and then again declines. The first and third peaks are shoulders, while the second peak is the formation's head.
Technical analysts generally consider a head and shoulders formation to be a very
bearish indication.
