Terre a mer Intensive Treatment Argan Oil Repair Hair Mask Cream a rich pure hydration treatment will provide a potent surge of moisture when your hair needs it most. Argan oil, amino acids and light silicones work together to infuse moisture deep into the capillary fibre. It will eliminate frizz by removing static and will leave hair exceptionally shiny. Amino acids are the basis of proteins that make up hair. These include serine, threonine, valine, arginine, aspartic acid, alanine, proline, isoleucine, phenylalanine and histidine. These amino acids have a natural affinity with hair and can penetrate the cuticle providing moisture deeper inside the hair shaft. Vitamin of B5 coats the hair and seals its surface, lubricating the hair shaft and making strands appear shiny.
