In shampoo, protein-rich ingredients like lentils give condition, shine and strength to the hair.
The lentil plant (Lens esculenta) itself is an annual, small and bushy legume of the pea family (Leguminosae). Its flowers are white or pale blue, containing lens-shaped seeds. They were thought to have originated in the Near East or Mediterranean region.
The lentil is low in fat and full of fibre, folic acid and iron. It is protein-rich, second only to the soya bean. Throughout time, it's been used beyond the culinary. The Egyptians believed them to have aphrodisiac and mind-enhancing properties; Roman women used a beauty paste made of honey and lentils to lighten their skin; Indian and Middle Eastern women have used lentils in beauty preparations and hair care for centuries.
