BONDING AGENT Multigrain Complex OS is 100% gluten‐free, as it is derived from quinoa, rice and amaranth. Hydrolyzed proteins help to form film around the hair strain while minimising transepidermal water loss, which makes them excellent for dry hair. Both Amaranth and Quinoa are classified as super foods, which are highly nutritious and easy to cultivate. Unlike most plant sources, the proteins isolated from Amaranth and Quinoa are complete or whole proteins, which means that they contain a proper balance of all the essential amino acids.
