Head & Shoulders is a brand of anti-dandruff shampoo produced by Procter & Gamble. Head & Shoulders Classic Clean Shampoo is the top selling shampoo in the United States by Dollar Sales.
Head & Shoulders was first introduced to the U.S. market in November 1961, as a blue-green shampoo formula. Unlike other shampoos, Head & Shoulders had relatively few variations until the late 1990s and early 2000s, and there are now in excess of ten different kinds of shampoo for different hair types under the Head & Shoulders banner. It has since then grown into a billion dollar brand.
A study conducted by University Medical Center Sart Tilman (Belgium) comparing the efficacy of the active ingredient in Head & Shoulders (zinc pyrithione) versus the active ingredient in Nizoral (ketoconazole) found that "Ketoconazole [Nizoral] 2% shampoo was significantly superior to zinc pyrithione [Head & Shoulders] 1% shampoo in the treatment of subjects with severe dandruff or seborrheic dermatitis of the scalp". (Skin Pharmacol Appl Skin Physiol. 2002 Nov-Dec;15(6):434-41.)
The brand's "Extra Strength" product had a cameo role in the 2001 film Evolution, where its startling copper orange color was shown. Head and Shoulders' original ocean blue formulation is more widely recognized.
