The Matrix Biolage Fiberstrong Shampoo and Conditioner Duo (13.5 oz each) is designed to strengthen fragile, damaged hair. This powerful duo is infused with bamboo extract and Intra-Cylane™, which work together to fortify and nourish hair, helping to reduce breakage while promoting healthier, more resilient strands. 

Fiberstrong Shampoo gently cleanses while reinforcing the hair structure, leaving it smooth, shiny, and less prone to breakage. 

Fiberstrong Conditioner deeply conditions and strengthens, leaving hair soft, manageable, and hydrated without weighing it down. This paraben-free duo is ideal for weak or brittle hair and is safe for color-treated hair, helping to restore strength and elasticity over time.
