One of the first findings obtained by the scientists with the help of the life cycle simulator was how the type and quantity of the lipid composition on and inside the hair varies over time. Lipids are natural fats, which make the hair surface shiny and supple. To do this, the scientists studied the hair after the artificial aging procedure using biochemical methods. They were ultimately able to characterize the wear pattern precisely and show which lipids had been ‘washed out’ in the course of time. This knowledge finally enabled the scientists to carry out a targeted search for a natural active substance that contains exactly the lipids that the hair loses. They found that the oil of amaranth, a South American cereal, has roughly the same fatty acid composition as the natural hair lipids and compensates for the lost lipids. In damaged hair, the missing fatty acids are replaced completely and individually, so that the hair regains strength, shine and flexibility. Moreover, split ends and hair breakage are appreciably reduced.

These results have been used as the basic technology in the development of products marketed under the name of Seah Hairspa with amaranth oil. Instead of amaranth oil, the Gliss Kur Oil Nutritive care line contains argan oil, which has a similar composition of unsaturated fatty acids.
