The Biolage Strength Recovery Deep Treatment Pack is a rinse off mask for especailly damaged hair that needs extra moisture, nourishment, and repair. With its rich, creamy texture, this mask leaves hair feeling conditioned with 73% less breakage after just one use (when used as a system). 

The Strength Recovery system of Shampoo, Conditioning Cream, Deep Treatment Pack and Strength Repairing Spray transforms hair to be 3x stronger after just one use, adding lightweight texture and health to damaged hair. Credit goes to the key ingredient of vegan squalane. When lipids are diminished, hair becomes rough, dull, brittle and split. Vegan squalan mimics hair’s natural lipids, which are critical to keeping hair healthy, shiny and strong, reducing breakage and increasing manageability. These formulas also contain soothing emollients that rush to the surface of hair, leaving it smoother and more nourished.
