Water covers 70% of the Earth’s surface but only 0.3% of water resources can be practically used.1 By 2025, two-thirds of the world’s population may be at risk of water scarcity.2 Each person directly consumes around 140 litres/day of water, 40% of it in the bathroom. The Energy Saving Trust reports that the greatest opportunities for saving water can be found in the bathroom, with showering being the largest water user in the home.3

The product is simply left in the hair and rinsed off later. These formulations can also absorb any excess oils.
