Revita delivers amino acids directly to hair shafts and follicles because these building blocks of protein add tensile strength to hair. Nature assembles amino acids to form keratin, the hard fibrous protein of hair, but the acids have to be replaced constantly as damage accumulates over time.

      Keratin protein, a polypeptide chain of amino acids joined by peptide bonds in a specific order, makes up 88 percent of hair. The alpha helix structure of keratin is a coil with 3.6 amino acids per turn and a peptide bond between the carbon atom of one and the nitrogen atom of the next.

      L-arginine, a semi-essential amino acid synthesized by the body from L-ornithine, supports the creation of protein through the transport and storage of nitrogen.

      Taurine (below) corrects rigidification of the connective sheaths surrounding pilosebaceous units, especially those affected by male pattern hair loss. Specific amino acids and their effects on hair growth have been published in both the patent registries and in the medical literature.

 L-cysteine (above right) speeds hair growth and increases shaft diameter, resulting in fuller hair. It has been reported to facilitate hair growth of longer duration. L-cysteine also gives antioxidant protection to the follicle. Users of topical n-acetyl-cysteine have reported hair regrowth.

      The combination of all these amino acids into a single shampoo, Revita, means the fastest possible nourishment of strands and follicles for the thickest possible hair. Concurrent systemic use of these amino acids, especially Taurine is highly recommended. The anti-fibrosis effects of oral taurine are well established, and is a primary constituent of several patented oral hair loss treaments in Europe.
