Amino Acid Hair Treatment: A restorative hair care treatment that infuses hair with amino acids, the building blocks of proteins. For instance, a keratin treatment is a popular amino acid hair treatment that strengthens hair and reduces frizz.
Amino acid hair treatments have gained prominence due to their hair strengthening and restorative properties. They replenish lost amino acids, making hair more resilient and less prone to breakage. A pivotal development was the discovery of the role of specific amino acids, like cysteine, in strengthening hair and preventing damage.
