Bamboo extract is a sought-after product in natural cosmetics. It is extracted from the stems and leaves of young bamboo plants. They are rich in flavonoids, which are said to have an antioxidant effect. Biotin, which is valuable for maintaining normal hair growth, skin and nails, is also found in abundance in bamboo extract. Another active ingredient is organically bound silicon, which can have a positive effect on hair, skin and connective tissue.
