Brylcreem first started in 1928 by County Chemicals (a British Company) made primarily for slicked back well groomed mens hair of the time. It was taken up by RAF pilots which lead them to be dubbed The Brylcreem Boys.
In the 50's it was worn not only by Greasers and Teds to keep up the quiff/pompadour, but also by conservative squares. Maintaining their well cut, neatly groomed hairstyle. By the 60's men started growing their hair long a little dab just wasn't enough and Brylcreem lost its popularity,
