Prell is a viscous, pearl-green shampoo and conditioner product manufactured by Scott's Liquid Gold-Inc through their Neoteric Cosmetics subsidiary.
History
Prell was introduced by Procter & Gamble in 1947. The original formula was a clear green concentrate packaged in a tube. In 1955 Prell was marketed for women "who want their hair to have that radiantly alive look". A woman held the Prell bottle with her hands on both sides, directly in front of her face.[1]
Prell and Head & Shoulders, also made by Procter & Gamble, were the two best-selling shampoos in the United States in June 1977. Procter & Gamble had the highest advertising budget in the shampoo industry.[2] The firm of Wells, Rich, Greene carried out advertising for Prell.[3] Prior to December 1, 1973, Prell billings were coordinated by Benton & Bowles
