It features a trivalent ion that builds new bonds through the creation of a 3-dimensional network inside the hair fibre. The Fibre Clinix regimen increases elasticity, resilience and leads to hair that is up to 10x stronger.<br />C21 TECHNOLOGY Virgin hair is protected by an outer layer of 21 hydrocarbons called proteolipids, a combination of proteins and fatty acids. Damaged hair loses this protective layer. The C21 Technology restores the C21-Lipid chains, which is more than the previous C18-Lipid chains. This brings the cuticle closer to natural perfection for improved shine, manageability and natural movement. ">
