This product is a replacement mask containing collagen, a fibrous protein made up of amino acid polypeptide chains. Collagen formation occurs during hair regeneration, ensuring complete restructuring of the hair fiber. Enriched with royal jelly, this formula has a high rebuilding power that revitalizes and restructures the hair fiber, restoring elasticity to the hair. It is recommended for sensitized, elastic, and chemically treated hair, and has a powerful effect in replenishing mass, making the strands stronger, more rigid, and shiny. This package includes one 450g jar of honey replacement mask.
