Truss Body Volume is a thermo-activated product designed to provide texture and volume to thin, oil-prone hair fibers. With an unsurpassed anti-aging action, hair feels lighter, softer and shinier thanks to the nano-repair formula that acts as an adhesive bonding agent. Amino acids penetrate the cortex of the hair cuticle to strengthen the internal structure, thereby increasing hair flexibility. A unique cereal protein forms a moisturizing, protective film over each strand, while the repair fiber contributes intense restoration from chemical and mechanical processes to ensure your hair is as healthy on the inside as it looks on the outside.
