•Bamboo(Bambusa spp.): the plant extract of the bamboo stem is particularly rich in organic silicon, one of the essential cofactors for the formation of the enzyme prolylhydrolase, which transforms proline into hydroxyproline, essential for the formation of collagen and glycosaminoglycans, responsible for the well-being of hair and nails.

•Zinc:element that plays an important role in many biological processes. Defined as an essential trace element or micronutrient, it contributes together with selenium to the maintenance of healthy hair and nails. It is indicated to protect cells from oxidative stress and to promote the functions of the immune system. • Selenium Selenium is an essential trace element involved in numerous biochemical processes as it is an important enzymatic cofactor and is a component of proteins, known as selenoproteins. It contributes together with zinc to the maintenance of normal hair and nails and is indicated to protect cells from oxidative stress.

• Biotin(D-biotin): an “essential” water-soluble vitamin of the B group that, since it cannot be produced directly by the human body, must be introduced with the diet. It is indicated to promote the metabolism of macronutrients and contributes to maintaining the well-being of the hair
