A woman with visibly messy hair transforming into perfectly smooth, shiny hair.

The ad opens with a woman with messy hair sitting at a reflective table. Her hair is then shown to become perfectly smooth and shiny. A bottle of Garnier Fructis Diamond Sleek spray is shown, followed by instructions on how to use it: spray on damp hair, then blow dry. The final shots show the woman with incredibly shiny, smooth hair, with text highlighting the product's benefits.
