Hair colouring brand Koleston used a great outdoor strategy to promote its range of natural hair dyes. The company erected a billboard by the sea-side coast of Beirut, Lebanon that created an interactive user experience by utilising the natural environment. The billboard had a die-cut stencil figure of a woman with long flowing hair. The colour of the hair changes throughout the day depending on the time and weather. The billboard cleverly conveys the brand proposition: Koleston Naturals uses natural ingredients in its products.
