Think like Koleston Naturals. Their innovative use of billboards re-inforces the beauty of nature by making use of the views right under our noses. Koleston Naturals is a hair colourant made from natural ingredients for women aged 20-40. The strategically placed billboards use a die-cut silhouette of a woman’s head to reveal the scene behind them. And so as the day progresses from morning to night, nature’s light changes to tell the simple story that Koleston Naturals enhances your looks naturally. Brilliant.
