Amino Acid Shampoo & Science

A 2007 article in the Journal of Cosmetic Science found, “When amino acids are applied to hair as the state of simple aqueous solution, uptake of the amino acids is mainly controlled by ionic equilibrium. When amino acids were incorporated in hair care formulations, the interaction between the amino acids and other ingredients. Uptake of pyrrolidone carboxylic acid (PCA), a derivative of glutamic acid, is enhanced by combining with arginine, an amino with strong affinity towards the hair. A hair conditioner incorporated with alanine improves hair surface hydrophobicity of bleach-damaged hair. Histidine and phenylalanine improve tensile strength. PCA was proved to be effective to improve colour-retention of dyed hair.”

Basically, this is all really fancy wording for:

  • When amino acids are applied to the hair as just a liquid,  the absorption of the amino acids depends on the absorption of the liquid into the hair
  • When the amino acids were added to a formulated conditioner the amino acids travelled more quickly to the hair
  • Hair has a particular affinity (or love) for the amino acid, Arginine, it acts as the “anchor” amino acid by absorbing quickly and encouraging other amino acids to absorb as well
  • A hair conditioner incorporated with Arginine improves the water-repelling property of bleach-damaged hair
  • Histidine and Phenylalanine amino acids improve the strength of each individual hair strand
  • Amino acids help improve dyed hair’s ability to keep it’s the vibrant colour for longer periods of time

The science doesn’t lie, amino acids are fantastic for not only hair growth but retention! Utilizing a bit in your routine will help you achieve the frizz-free definition and shine you have always dreamed about.
