Every drop matters to Swiss start-up Gjosa and French cosmetics giant L'Oréal, who have collaborated in developing an eco-friendly water-saving solution for hair salons.

The system comprises a multi-channel shower head that conveys water and haircare products while reducing approximately 75% of water volume and rinsing the shampoo with only 1.5 litres of water, instead of the usual 8 litres.

Based in Bienne, the environmental technology company developed the low-speed shower head, which breaks up the flow of water while accelerating the speed of the droplets, for eco-shampooing and rinsing. Inspired by Icelandic geysers, the patented design of the shower head reduces the flow of water to 2 litres per minute, compared to an average of 11 litres with ordinary equipment.

L'Oréal scientists, meanwhile, formulated easier-to-rinse shampoos applied directly through the shower head. Some water jet parameters have been adjusted in real conditions to obtain the right rinse, without splashing, and reduce water and energy consumption by almost 70%. This will help solve the problem of water consumption, which is increasing worldwide and has raised concern among the United Nations (UN).

The UN states that water is at the core of sustainable development, and is critical for socio-economic development, energy and food production, healthy ecosystems and for human survival itself.

The UN has also declared 2018-2028 as the International Decade For Action on "Water For Sustainable Development".

The use of shampoo and shower gel requires a considerable amount of water, often with unsustainable degrees of wastage. Besides reducing water consumption, the innovative system by Gjosa and L'Oréal also saves energy, as there is less water to be heated. It also provides consumers with a new experience with its dynamic rinsing.

Tested in L'Oréal laboratories, prototypes of Gjosa's eco-shower head are at present on trial in several salons before the technology become available to the professional hair salon market.
