With 40% less protein than thick hair, fine hair is 10x more prone to breakage. Our experts created our Unbreakable Care™ collection to strengthen fine hair by harnessing the power of Arginine amino acids, which have nearly 2x more inner core-strengthening properties. We used these findings to source natural proteins that are high in Arginine amino acids and created a system with Advanced Keratin Protein, Collagen, and Biotin to deliver stronger, fuller, thicker-looking hair.
