Biolage Hydra Source Shampoo is a professional salon-grade cleanser engineered to quench dry, thirsty hair. Inspired by the moisture-retaining properties of aloe, this advanced formula is infused with micro-filtered aloe vera and fermented hyaluronic acid to optimize your hair's moisture balance. It gently cleanses away impurities without stripping natural oils, providing up to 6x more hydration after just a single use. By locking in weightless moisture, it shields your hair cuticles against future damage, leaving strands noticeably soft, shiny, free of frizz, and easy to manage. Apply to wet hair and lather gently using a massaging motion. Rinse thoroughly with warm water. For optimal results, follow with Biolage Hydra Source Conditioning Balm or Detangling Solution to lock in maximum softness. Perfect for straight, wavy, curly, and coily hair textures. This color-safe formula helps repair stressed textures to tame stubborn frizz and minimize flyaways. Certified cruelty-free and 100% vegan with zero parabens, silicones, or mineral oils. 13.5 Fl. Oz. / 400 ml
